326182c3e3 Made DirectMessageTarget's destructor private to avoid potential future
errors. This object should never be deleted directly as it's ref counted, 
only when its last ref is Release()'d.

2365e7b574 BSlider had code for doing double buffered drawing, but was
disabled by default. Appears to work correctly though, so
enabling it since it produces far less flicker here.

f6d52cb737 - Added operator = implementation to rgb_color for convenience.
- Major cleanup of Appearance prefs - colors are now dynamically
  read from the app_server, and updating them also works, but
  triggers a bug: the state of the current window somehow gets
  confused, i.e. if I update the panel background color, for some
  reason the color of the BButtons in the appearance pref change color
  and also the textviews begin misbehaving. Have not yet tracked down
  the cause of this, but newly created windows after making the change
  do show up with the updated color and behave properly. Also vastly
  simplified the pref and cleaned up some obsolete definitions.

87df690150 * Replaced the UTF8ToCharCode function with one that handles invalid chars
correctly (or at all...)
* Use the common 0xfffd character as a substitute for invalid characters
* Corrected comment

This function is used by the app_server to convert the UTF8 strings to char
codes to feed FreeType. Using a non space substitute character at least for
now, as it makes it more obvious where invalid characters are present.
I tested this change with some UTF8 test files and it seems to work well.

d273d00822 * Fixed previous version of UTF8CountBytes() and put it in again: it was
breaking out of the loop too early, and would therefore miss the last
  character.
* Replaced UTF8CountChars() with a short and safe version as well.

ccf6ad1d8b Reverted to the previous version. Axel, your change completely broke all kinds
of stuff. I think the trouble is that you keep decrementing charCount while
still inside the same UTF8 glyph. I cannot really tell, I am hoping you don't
mind me reverting to the old version, since the new one is only three lines,
so it should be easy to correct and re-commit.

b5a5aebc90 * Added a set_to_defaults() function to the address module: it can be used
to retrieve the default settings for the netmask/broadcast depending on the
  specified address/netmask.
* interface_protocol_control() now uses this to reset the broadcast/netmask
  to their default values on SIOCSIFADDR resp. the former only on
  SIOCSIFNETMASK.
* This fixes bug #1861.

a77ed12b25 * Removed obsolete "ident" parameter from devfs_publish_device().
* driver_entry::api_version now stores the actual version instead of a
  pointer to it.
* Renamed node_path_entry to path_entry and reused it for driver 
  reloading: handle_driver_events() will now also check for drivers to
  add in the sDriversToAdd list.
* Added new devfs_driver_added(), and devfs_driver_removed() functions
  that trigger certain driver actions.
* Implemented notifying devfs on B_ENTRY_CREATED, B_ENTRY_REMOVED, and
  B_ENTRY_MOVED events in probe.cpp. The watched directory inode numbers
  are now stored in a hash for B_ENTRY_MOVED.
* unpublish_driver() did not actually delete the node, it only marked
  it removable since we never get/put the node. We now do, and so the
  node is actually removed as intended.
* Added "devfs_driver" KDL command.
* Minor cleanup.

* Changed HaikuBuildCompatibility.h so that it does not define the things
  that are already in the build headers.

43948ef628 - Fix an error in SwapItems where the item tops would not be swapped
if the items were the same height.
- Modified _RecalcItemTops to allow us to specify a range instead of 
just a starting point. This is useful for cases like Swap, where 
only the items in between those being swapped need to be 
recalculated.

46ea5b1e49 Further improvements to auto scrolling and text rect + container view resizing:
* Renaming things in Tracker list mode no longer magically grows the text view.
* ScrollToOffset() is not supposed to depend on the existence of any scroll
  bars, in R5 text views simply scroll to where they need to. This fixes
  renaming things in Tracker when hitting the window bounds (text widget stops
  growing and starts to autoscroll) and also the Text tool in WonderBrush.
* _ScrollToOffset() is therefor no longer needed.
* The insets of the text rect are not so interesting as the original width.
  In auto resizing mode, the original width is important when there is no
  container view. In this setup, the text rect auto resizing is mainly needed
  for auto scrolling, but it should never shrink below the original size.
* Further improved auto scrolling for right aligned and center aligned text
  views, it works like R5 now. Also take the line height into account when
  checking for the bounds bottom. Removed extra spacing for vertical
  scrolling.

351b7a2d24 * Added B_WATCH_INTERIM_STAT, and B_STAT_INTERIM_UPDATE definitions to
NodeMonitor.h.
* The latter will be set in "statFields" for interim updates when you have
  asked to get them via the former.
* BFS now uses the B_STAT_INTERIM_UPDATE flag for sending updates to actively
  written files.
* This makes us more compatible with BeOS again; if you only asked for
  B_WATCH_STAT, you will now only receive a notification if the file in
  question has been closed.
* Tracker now uses B_WATCH_INTERIM_STAT to always get all updates (ie.
  downloading a file will update its size and modification time in Tracker
  periodically during the download).
* Wether "needsTrimming" was true or not has no influence on wether or not
  the size index needs to be updated in BFS - only the actual file size is
  stored there, not the on-disk size.
* Added a TODO comment in Inode::WriteAt() that it would actually need to
  update the size index when changing the file size, not when the file has
  been closed (but that's probably too slow).

b8872c02c1 BTextControl:
* Placed _BTextInput_ into BPrivate namespace.
* Made _BTextInput_::AlignTextRect() smarter, it centers the line vertically,
  for the case that the BTextControl has a larger label font. Improved insets
  for asthetics.
* Used _BTextInput_::AlignTextRect() consistently in BTextControl, no more
  custom calls to SetTextRect(). Account for minimum vertical inset of 2
  pixels in GetPreferredSize().
* Consistendly select all text when gaining focus in _BTextInput_.
* Override MouseDown() in case the control did not have focus before, or else
  BTextView::MouseDown() will deselct the text again and place the cursor.
  (in line with BeOS behavior)
* Removed unused fBool member from _BTextInput_ and other cleanup.

BTextView:
* Reimplemented BTextView::_AutoResize() so that it works well with
  BTextControl and autoscrolling when the alignment is not B_ALIGN_LEFT.
  I needed two new members for this, fLeftInset and fRightInset which are
  the original insets from the fTextRects. It might currently be broken
  for renaming things in Tracker, I will have to check. _AutoResize() no
  longer messes up the fTextRect insets.
* Fixed stray carrets sometimes being left over, mostly when auto scrolling,
  but I observed them in other cases as well.
* Prevent negative scrolling offsets when autoscrolling. Fixes weird scrolling
  offsets when navigating to the left.
* Reset scrolling to B_ORIGIN when SetText() is called. Fixes for example
  starting to type in the middle of the control in Vision when entering new
  text and autoscrolling was triggered before.

workspaces view can now be any view in the hierarchy.
* Added private view flag kWorkspacesViewFlag that identifies such a
  view - note though, that you must not remove a view before closing or
  hiding its window for now (and that you still need to set the 
  kWorkspacesWindowFlag, too).
* Fixed Workspaces check for valid screen coordinates; after a crash, it
  managed to open its window offscreen for me.
* Added a ViewLayer method FindView() that finds a view with the 
  specified flags set.

562e2f204a * Removed unused team::pending_signals.
* Added team::flags. Currently only used for setting a flag when a team
  has exec()ed.
* Some improvements of _user_setpgid():
  - It failed incorrectly when the target process was a process group
    leader. According to the standard it shall fail when the process is
    a session leader. Moving a process group leader to another process
    group is fine, even if that leaves the group leaderless.
  - Fixed race conditions. We need to recheck the error conditions when
    we hold the team spinlock. Otherwise the situation could change
    while we allocated the new process group. This was one of the
    reasons for bug #1799 -- after the shell fork()'s both parent and
    child invoke setpgid() for the child.
  - Fixed behavior for pid == pgid. It doesn't necessarily mean that a
    new group has to be created.
  - Fixed update of target process group orphaned state.
  - Squashed TODO: setpgid() on a child is supposed to fail after the
    child has exec()ed.

cf46897b4c Use a dedicated heap to allocate everything that is needed during heap growth.
This eliminates the edge case where the grow thread would not be able to create
a new area because no memory could be allocated for the allocation of the area.
As this case cannot happen anymore, it is also not possible to deadlock in
memalign. Therefore the timeout (which would only have prevented the deadlock
but wouldn't have solved the edge case anyway) has been removed too.
Add options to dump the dedicated grow heap and to only print the current heap
count to the "heap" debugger command.

c72d22a5e8 Converting relative timeouts into absolute ones is fine in principle,
but there's a special handling for 0 us relative timeouts. Syscalls
usually return B_WOULD_BLOCK instead of B_TIMED_OUT in this case, and
callers might explicitely check for it. Hence we don't convert 0 us
timeouts anymore. gdb works again.

058494285a axeld + bonefish:
* Added syscall restart support for connect(), accept(), send(), recv(),
  which are implemented via ioctl()s. The actual restart support is done
  in the net stack driver's ioctl() hook. Lower layers need to correctly
  deal with socket timeouts, though, for which the stack module provides
  support functions.
* TCPEndpoint::_WaitForEstablished() does abort now when an error
  occurred earlier, so that trying to connect to an unused port fails
  immediately, as it should.
* Fixed and refactored TCP connection reset handling. The new
  TCPEndpoint::_HandleReset() does the job. Got rid of
  TCPEndpoint::fError.
* Fixed sequence numbers for SYNC/FINI packets.
* The former two fix the problem that connections wouldn't be closed
  correctly and could even be reused when trying to connect again (as
  was reproducible with svnserve + svn).
* Some style cleanup in CPEndpoint.h.

4048494ce4 axeld + bonefish:
* Implemented automatic syscall restarts:
  - A syscall can indicate that it has been interrupted and can be
    restarted by setting a respective bit in thread::flags. It can
    store parameters it wants to be preserved for the restart in
    thread::syscall_restart::parameters. Another thread::flags bit
    indicates whether it has been restarted.
  - handle_signals() clears the restart flag, if the handled signal
    has a handler function installed and SA_RESTART is not set. Another
    thread flag (THREAD_FLAGS_DONT_RESTART_SYSCALL) can prevent syscalls
    from being restarted, even if they could be (not used yet, but we
    might want to use it in resume_thread(), so that we stay
    behaviorally compatible with BeOS).
  - The architecture specific syscall handler restarts the syscall, if
    the restart flag is set. Implemented for x86 only.
  - Added some support functions in the private <syscall_restart.h> to
    simplify the syscall restart code in the syscalls.
  - Adjusted all syscalls that can potentially be restarted accordingly.
  - _user_ioctl() sets new thread flag THREAD_FLAGS_IOCTL_SYSCALL while
    calling the underlying FS's/driver's hook, so that syscall restarts
    can also be supported there.
* thread_at_kernel_exit() invokes handle_signals() in a loop now, as
  long as the latter indicates that the thread shall be suspended, so
  that after waking up signals received in the meantime will be handled
  before the thread returns to userland. Adjusted handle_signals()
  accordingly -- when encountering a suspending signal we don't check
  for further signals.
* Fixed sigsuspend(): Suspending the thread and rescheduling doesn't
  result in the correct behavior. Instead we employ a temporary
  condition variable and interruptably wait on it. The POSIX test
  suite test passes, now.
* Made the switch_sem[_etc]() behavior on interruption consistent.
  Depending on when the signal arrived (before the call or when already
  waiting) the first semaphore would or wouldn't be released. Now we
  consistently release it.
* Refactored _user_{read,write}[v]() syscalls. Use a common function for
  either pair. The iovec version doesn't fail anymore, if anything could
  be read/written at all. It also checks whether a complete vector
  could be read/written, so that we won't skip data, if the underlying
  FS/driver couldn't read/write more ATM.
* Some refactoring in the x86 syscall handler: The int 99 and sysenter
  handlers use a common subroutine to avoid code duplication.

4af6cd5f38 Adding two debug features to the new heap implementation:
* Tracing of allocations, reallocations and frees
* Leak checking infrastructure to dump allocations

The leak checking code records the team and thread id when an allocation is
made as well as stores the originally requested size. It also adds the
"allocations" debugger command that can dump all current allocations (usually
a huge list) or filter by either a team or thread id. This way it's easily
possible to find leftover allocations of no more active teams/threads.
Combined with the tracing support one might be able to track down the time and
reason of an allocation and possibly find the corresponding leak if it is one.
Note that kernel heap leak checking has to be enabled manually by setting the
KERNEL_HEAP_LEAK_CHECK define to 1.
