- Fixed deadlock in xsi_sem_undo - RecordUndo
- Fixed issue in xsi_sem_undo: if the semaphore set does not exist
anymore, ignore the request but do remove the process from the sUndoList,
which wasn't previously done.
- free() in ClearUndos was called with interrupts disabled
- when a semaphore set ends to exist, remove all it's sem_undo request as it's ID
will be reused in the future.

- iospace should now be initialized correctly, at least the kernel goes much further.

* sCopied wasn't needed anymore due to the sManagedEnviron variable.
* Minor cleanup, added a description to copy_environ_to_heap_if_needed().

the environment would crash on Haiku. Added a small test application that
just checks every one of those.
* Fixed env locking (in userland, you better check against B_INTERRUPTED).
* Made our code safe against an environ of NULL.
* There is now an additional sManagedEnviron that points to the environment
our code actually managed; whenever an application overrides environ, we'll
get aware of it with the next *env() function invocation, and will handle
it adequately.
* Added non-POSIX clearenv() function.

* Improve code in FileUtils to copy attributes in chunks and improve
error checking. Should also copy 0 size attributes now, since those are valid.
* Craft SoundConsumer towards more style guide compliance.
* Use new (std::nothrow) and check result.

running - this fixes several cases where someone could see outdated data
when a transaction had to be reverted (the time between unlocking the inode
and actually reverting the blocks). For that, Inodes can now be put into a
singly linked list.
* Added a TODO in Inode::WriteAt() which explains why it cannot use the above
method: seems that our VFS/VM locking model isn't really that good.
* Fixed a possible deadlock in Attribute::_Truncate() where the inode write
lock was held before starting the transaction.
* Added an InodeReadLocker convenience class, that should be used instead
of ReadLocker - Inode::Lock() only still exists because of the needs of
bfs_io().
* Moved the bfs_io() callback hooks out of the exported module API region,
and removed their bfs_ prefix.
* Added a Volume::IsInitializing() method that should be used rather than
checking if Volume::ID() is >= 0.
* Removed the MultiInodeLocker again, as it's pretty much superfluous now.
* Moved openModeToAccess() to the Utility.h header.
* Minor cleanup.

inode - unlike get_vnode() the busy flag won't prevent you from getting that
reference.
* Changed put_vnode() to return an error in case the vnode couldn't be found.

in steal_pages() which uses the number of pages in the inactive queue as
return criterion. It would thus return, if only marker pages were in the
queue and no page could be stolen. This led to a busy loop in
vm_page_allocate_page(). The whole system would become unusable when the
thread in question was the heap grower, since it would starve everyone
else due to its high priority.

user_{memcpy,memset}(), since that can cause a page fault, which needs
pages and might try to steal some from our cache.

new parent directories. This would only be necessary in case it's a directory,
but we do it always now.
* This fixes bug #2556.

partially (e.g. due to hitting the end of file). The respective
classes have grown new methods and attributes to deal with that. The
"finished" callbacks have got additional parameters to indicate
whether the transfer was only partial and how much has been
transferred. Other callbacks and functions have a size_t* in/out
parameter instead of a simple size_t, now.
* vfs_{read,write}_pages() do now use the I/O request framework instead
of the underlying FS's {read,write}_pages() hooks (those should be
unused now). Furthermore they've got an additional "flags" parameter,
which is passed to IORequest::Init(), i.e. it allows to specify that
the given vecs refer to physical addresses.
* The file cache's read_into_cache() reads directly into physical
pages, now.
* Fixed bug in DoIO::IO(): The offset was not adjusted, so that all
pages were incorrectly transferred from/to the same location.
* Fixed broken subrequest scheduling loop head in
do_iterative_fd_io_iterate().
* Adjusted the test driver and implemented its io() hook. Using this
driver I/O requests are passed all the way from the VFS/VM to the
driver and through the I/O scheduler. It even seems to work. :-)
* Added missing const to the iovec* parameter of the IORequest::Init()
methods.
* Disabled some debug output by default. Added new optional debug
output.

* get rid of three of them, i don't know why they where implemented in the first place
* fix broken scrollbar adjustment
* cleanup DocInfoWindow.h and DocInfoWindow.cpp
* make the window resizable and get rid of the tabview

* Moved locking the data stream out of the BPlusTree methods; this fixes at
least two locations where another thread could have seen outdated/incorrect
data.
* Removed some superfluous code in bfs_rename(): we don't have to revert to the
previous situation, the transaction does this for us automatically.
* Added a simple MultiWriteLocker, even though it's not really necessary anymore
(since we always hold the transaction lock first when we lock more than one
inode at a time).
* Inode::Create() called InodeAllocator::Keep() a bit too early, the file cache
and map wasn't created and assigned yet.
* InodeAllocator now keeps the inode write locked.

is defined to 1; this allows asserting the read lock case, too.
* Added ASSERT_{READ|WRITE}_LOCKED_RW_LOCK() macros. The read assertion is only
working when KDEBUG_RW_LOCK_DEBUG is defined to 1, the write assertion works
always.

* Added "syslog" command that dumps the contents of the syslog ring buffer into
KDL. Use the '-n' option to only show what hasn't been sent to the syslog
daemon yet.
* When entering the kernel debugger, the current thread ID and name are also
printed (not only the current CPU).

small clipping holes to the TestView user clipping.
* Added a bunch of new tests. Here are some numbers from the test environment,
which is similar to running Haiku in VESA mode:
Horizontal lines per second:
Haiku: 192964.663 (117,7%)
ZETA: 163977.006
Vertical lines per second:
Haiku: 90109.985 (276.9%)
ZETA: 32538.458
Random lines per second:
Haiku: 7998.451 (23.1%)
ZETA: 34602.539
Random colored lines per second:
Haiku: 7976.437 (22.9%)
ZETA: 34788.247
Random clipped lines per second:
Haiku: 262.180 (2.5%)
ZETA: 10394.794
Clipped glyphs per second:
Haiku: 5911.526 (1.0%)
ZETA: 590508.726
Obviously the clipping performance is a punch in the stomache.

of the Haiku app_server. The immediate comparison are of course BeOS and ZETA.
Currently, it measures the performance of drawing untransformed text. For
now, I have only tested on ZETA and the app_server testing environment. Will
let you know my findings with Haiku running on real hardware.

by myself:
* renamed xsi_do_undo() to xsi_sem_undo() (there is more to XSI than sems).
* Fixed coding style issues in sys/sem.h and xsi_sem.cpp.
* Added _kern_*() syscall prototypes to syscalls.h.
* Added a TODO in xsi_sem.cpp and xsi_semaphore.h about moving union semun to
a shared header.
* Made the team::xsi_sem_undo_requests int32 - due to padding, it would have
needed 4 bytes anyway; please always use specific types over int/short/long.
* xsi_sem_undo() now checks if it needs to do anything - the calls in team.cpp
no longer needs to do this.
