the ipc hash table lock along with the semaphore set hash table lock were
hold, thinking (wrongly) that the semaphore set lock itself was not needed.
What could happen was that another process on semop could have gained the lock
of the set itself, and then release the semaphore set hash table lock.
This would make it think that the set was still valid, while it could have
actually been deleted right after it release the semaphore set hash table lock.
Same would have happened for any other processes waiting on the semaphore set
mutex queue. By calling the lock on the mutex when deleting the set, it
*should be* safe to assume that there is no one else waiting on its queue,
since the list of waiters is handled in a FIFO way.
As far as I can see from the mutex_destroy code, it looks safe to hold the lock
when calling this function. Please confirm.

* Changed the copyright line to say "The Haiku project", similar to the GNU
and BSD copyrights. Then a clarifying sentence as discussed on the developer
mailing list.
* Removed the outdated Team list in favor of a "Most influential developers"
list with the top contributors of the past and the present in order of
SVN commit numbers. It could be argued that Travis should be part of this
list but he is already mentioned later with a special note. I used this
wording to indicate that it could also mention no longer active, but still
"most influential" developers. "Lead developers" or "Core developers" would
not have this aspect.
* Created a new "Website, Marketing & Documentation" section which gives
hopefully all or at least most people a more prominent mention which are
contributing most in this area. Waldemar Kornewald could be moved to this
list as well. Koki was not mentioned anywhere before, which definitely needed
to be corrected! :-)
* Maurice Kalinowski and Fredrik Modeen are now commiters.
* Added Andrej Spielmann (Subpixel Anti-aliasing) to the developers list, since
he has commit access too now.
* Added David Powell to list of contributors, for his recent patch to the
boot splash generator and boot loader.
* Added Copyright for CQuantizer (part of the mentioned patch from David)
If you have suggestions for improvements, please shoot, especially if I forgot
someone!

#591. The helper class could be reused for similar situations (ex: Tracker context menu and
drag detection). See the brief doc in the code. Comments welcomed!

* Removed unnecessary header Vector.h
* Removed HasSemaphoreSet method: since there will be an IPC table for each
subsystem, if a key exist, it already has a semaphore set associated
with it

inherit it.
* IOScheduler::ScheduleRequest() uses the request's thread and team now
instead of the current one. Otherwise for requests processed
iteratively this would always be the I/O scheduler's notifier thread.
* Also get the thread's I/O priority now. It's still ignored later,
though.

vector at the end of the file will be aligned to the given value.
* BFS uses an alignment of 512 bytes (should be block size of the
underlying device or BFS block size, whatever is less), which should
be fine, since file data are only stored in BFS blocks. This totally
avoids any partial operations at the I/O scheduler level, thus saving
disk operations. Not that I could measure any performance difference.
Theoretically it should help a lot though, particularly when dealing
with lots of small files, since we avoid using bounce buffers, which
are (a) limited in number and (b) require copying of the data.

job alright.

* swap_file_add() open()s the swap file now with O_NOCACHE and
swap_file_delete() closes it. This squashes a TODO (the file cache
wasn't kept disabled for the swap file before).
* swap_file_add() only adds swap files that can actually be used (i.e.
non 0-sized ones).

swapped out, we would increase the committment unnecessarily
(potentially even beyond the size of the cache).

InitCheck() method. :)

* Implement color palette generation for the boot splash images in the
generate_boot_screen build tool. Only 4-bit screen support is missing now.
* Adopted images.h with the new results from generate_boot_screen.
This should fix black boot screens for graphics cards that don't support
true color modes for the native resolution. I've tried to find the ticket,
#2177 almost looks like the one, but it looks more like the mode is out
of range if I understand the ticket right.
Thanks a lot, David, and sorry it took so very long to apply your patch!

Powel. The functionality was written by Jeff Prosise and Davide Pizzolato and
has been cleaned up and adopted to the Haiku coding style by David Powell and
myself. The class can perform a color quantization for generating the optimal
color index palette (with given maximum size) from a given RGBA image.
