8560d1885b * The runtime_loader's test_executable() no longer analyzes the
executable permissions of the file by hand. We use _kern_access()
  instead, which also handles the root case correctly.
* The user and group arguments of test_executable() aren't needed any
  longer.

55ef60a5ae * Removed the Copyright image/rendering.
* Fixed the icons image, it was upside down.
* Support the new 24 bit boot screen images in the boot_loader and the kernel.
* Prepare the code for future indexed versions of the boot screen images.
  But the generate_boot_screen tool currently does not generate those.

  icon.

aa727f6643 patch by Artur Wyszynski (aljen):
* Added the feature of an animated boot screen (icons lighting up at
  different boot stages).
* Added first version of new boot splash images, generated by the new
  hsbg tool. (Also finally contains the "new" Haiku logo.)

changes by myself:
* Added Artur to the contributors list in About System.
* Fixed some left overs in the patch, kept tracing turned off.

TODO:
* Remove the need for hard coding the icon positions. (Maybe generate
  those from hsbg and put them into images.h? Have user provide icon
  spacing/offsets at the command line for hsbg?)
* Rename the stages to something meaningful.
* Use hsbg as a build system tool and generate images.h during build
  from PNGs provided in the artwork folder.

4a7f236b07 Process groups are now reference-counted. Processes in a group as well
as the death entries of a deceased processes that were in this group
and have not yet been reaped hold references to the group, so that it
won't be deleted until the group is empty and all gone group members
have been reaped. This fixes #1799 at last.

a433b9febf Rewrite and activate message passing by area. Passing by area works now with
the new sematic of transfer_area so a message area is transfered into the right
teams' address space and it does not need to be cloned there anymore. Passing
by area is only used for messages bigger than a certain size (currently
hardcoded to 40KB) which should be somehow bound to the max port message size.
This makes passing large messages (i.e. > the port limit) possible, so for
example copy&paste of long text, image data, etc. should now work.
Got rid of the fClonedArea member as it is not necessary with the new design,
renamed shared_area to message_area in the private message_header, avoid
an unnecessary allocation of the header for the copy constructors, check
allocations in a few more places and some minor cleanup.

d1189f0b05 Naive implementation of transfer_area(). It follows the suggested sematics
of the resolved ToDo, but could probably be made more efficient. Instead of
transfering the area, the area is cloned into the target teams' address space
and the original is deleted. This generates a new area_id for the transfered
area (as suggested by the ToDo). Updated syscall prototypes according to the
status_t to area_id return type change.

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.

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.

  to their default values on SIOCSIFADDR resp. the former only on

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.

f9bbab8848 * First steps towards a more flexible workspaces view handling: the
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.

5c4d1c5e21 Complete rework of the heap implementation. Freelists are now part of the pages
and pages are now kept in lists as well. This allows to return free pages once
a bin does not need them anymore. Partially filled pages are kept in a sorted
linked list so that allocation will always happen on the fullest page - this
favours having full pages and makes it more likely lightly used pages will get
completely empty so they can be returned. Generally this now goes more in the
direction of a slab allocator.
The allocation logic has been extracted, so a heap is now simply attachable to
a region of memory. This allows for multiple heaps and for dynamic growing. In
case the allocator runs out of free pages, an asynchronous growing thread is
notified to create a new area and attach a new heap to it.
By default the kernel heap is now set to 16MB and grows by 8MB each time all
heaps run full.
This should solve quite a few issues, like certain bins just claiming all pages
so that even if there is free space nothing can be allocated. Also it obviously
does aways with filling the heap page by page until it overgrows.
I think this is now a well performing and scalable allocator we can live with
for quite some time. It is well tested under emulation and real hardware and
performs as expected. If problems come up there is an extensive sanity checker
that can be enabled by PARANOID_VALIDATION that covers most aspects of the
allocator. For normal operation this is not necessary though and is therefore
disabled by default.

62cb58a8ef Make print_server track Transport addons too. This is because some of the NewTransportAddOns(tm) can also autodetect devices, e.g. USB printers. For this, the print_server needs to keep those transport addons loaded at all times. This code now also enables dynamic Transport discovery for the Printer prefs, e.g. 'hey print_server GET Transport 0' or 'hey print_server GET Transport 'USB Port'' will now work too ;)
