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.

with an empty queue, it crashed. sem_info::latest_holder is obviously not
set correctly, and should be fixed.
Some cosmetics.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9771 a95241bf-73f2-0310-859d-f6bbb57e9c96
ignored completely (so that zero and below become valid).

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.

Also removed syscall for that function (shouldn't have been there in the
first place, anyway).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9325 a95241bf-73f2-0310-859d-f6bbb57e9c96
syscalls or to the syscall mechanism (which exposed naming and parameter
inconsistencies).

to deny further port/sem allocation (and also simplifies port/sem stats).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7570 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added system_info.c to the build.
Added stats support functions to sems & ports.

Implemented the B_CURRENT_TEAM mechanism for _get_next_sem_info().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6691 a95241bf-73f2-0310-859d-f6bbb57e9c96
with B_OS_NAME_LENGTH, make use of the IS_USER_ADDRESS() macro, etc.

Replaced some old error codes.
Explained a bit more how to solve a race condition.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6681 a95241bf-73f2-0310-859d-f6bbb57e9c96
Implemented realloc().
Adapted all other sources, some minor cleanups in some files as well.

for a valid team id.
Added a comment about a race condition in set_sem_owner().
Some minor style changes.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1309 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.

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.

- catch up with the changes to the interrupt functions
- change the way we handle the list of handlers to use a standard
function rather than a home spun one :)
- don't add every function on a pci device as a seperate device
- add more info to the pci_info structure
- when FULL_MONTY turned on show more information
