Salvatore Benedetto f273b13ddb * Renamed xsi_ipc_init() to xsi_sem_init() as there will be a xsi_msg_init()
for message queue
* 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

Salvatore Benedetto 9309ec8635 Start implementing POSIX message queue IPC
* Implemented _kern_msgget()

Work in progress, some stuff may be removed.

Salvatore Benedetto 6ae7f6879f * Reworked the way sem_undo requests are processed by following
Ingo suggestions: instead of having one global sem_undo list,
  we now have two local list, one per semaphore set and one per team
  which is held in its xsi_sem_context structure, along with a mutex.
  A mutex has also been added to the semaphore set class in order to
  protect the local list, but also in order to (hopefully) improve
  concurrency.

Salvatore Benedetto 51daeb7147 - Fixed warnings
- 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.

Axel Dörfler 47ca7595ca First patch by Salvatore to implement XSI semaphores with a few changes
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.

Ingo Weinhold 6b202f4e3d * Introduced new header directory headers/private/system which is supposed
to contain headers shared by kernel and userland (mainly libroot).
* Moved quite a few private kernel headers to the new location. Split
  several kernel headers into a shared part and one that is still kernel
  private. Adjusted all affected Jamfiles and source in the standard x86
  build accordingly. The build for other architectures and for test code
  may be broken.
* Quite a bit of userland code still includes private kernel headers.
  Mostly those are <util/*> headers. The ones that aren't strictly
  kernel-only should be moved to some other place (maybe
  headers/private/shared/util).

Ingo Weinhold 01b1098795 * Fixed some misunderstanding regarding the _POSIX_* macros. They are
not supposed to be passed to pathconf() or sysconf().
* Added POSIX semaphore related macros.
