e3954f5a94 acquire_sem_etc() really didn't like the combination of B_RELATIVE_TIMEOUT
and B_INFINITE_TIMEOUT -- it now does and won't start a timer anymore in
this situation. Reported by Ingo.

07bdb9c6ea Got rid of gSemRegion as it is never really used.
Renamed all static global variables to have the 's' prefix.
acquire_sem_etc() now fails if B_RELATIVE_TIMEOUT and B_ABSOLUTE_TIMEOUT
are both set.

2786541fbe Fixed a crashing bug in fill_sem_info() - if it was called for a semaphore
with an empty queue, it crashed. sem_info::latest_holder is obviously not
set correctly, and should be fixed.
Some cosmetics.

b767f41204 BeGeistert checkin: if B_RELEASE_ALL is used, the "count" argument should be
ignored completely (so that zero and below become valid).

48e64cd7c8 Added two experimental release_sem_etc() flags (both should stay, but they
may be renamed):
- B_RELEASE_ALL: the semaphore count is set to 0, all waiting threads are released
  (the "count" argument of release_etc_sem() is ignored then)
- B_RELEASE_IF_WAITING_ONLY: the semaphore count is only decreased if there
  are any waiting threads; ie. the semaphore is signaled
Together, they will make the pthread_cond_*() functions easy to implement, and
they come in handy at other places, too.
Removed release_threads variable in release_sem_etc(), as it was useless.

634a41725a The main reason I commit this: the last change also made set_sem_owner() to check
for a valid team id.
Added a comment about a race condition in set_sem_owner().

3fa1fa66f1 Cleaned up the source, made it compatible with our style guide (i.e. global
variables now have the 'g' prefix).
Fixed a very unlikely race condition in create_sem_etc() (can only happen if
that call isn't used properly).
Fixed some wrong return values (i.e. B_BAD_TEAM_ID wasn't returned anywhere).
Optimized _get_next_sem_info(): it now only grabs the semaphore lock
if it has good reason to do so.
Added some comments.

75c97114f7 Change int into status_t, and other changes for better BeOS type compatiblitly.
This change also introduces a lot of new warnings concerning printf format
anomalies. Please do NOT fix them. Currently, int32 (and also status_t)
is of type int, but it will be of type long (BeOS compatible) soon, and
these warnings will disasappear.

91363a4278 Converted thread states to BeOS equivalents (excluding THREAD_STATE_FREE_ON_RESCHED, which will probably go away once the slab allocator is in). Converted priorities to BeOS equivalents; we now have 60 priority queues to map the 120 BeOS priority levels (which have a granularity of 2, thanks Axel) plus the idle queue. Fixed PS.
