24df65921b Merged signals-merge branch into trunk with the following changes:
* Reorganized the kernel locking related to threads and teams.
* We now discriminate correctly between process and thread signals. Signal
  handlers have been moved to teams. Fixes #5679.
* Implemented real-time signal support, including signal queuing, SA_SIGINFO
  support, sigqueue(), sigwaitinfo(), sigtimedwait(), waitid(), and the addition
  of the real-time signal range. Closes #1935 and #2695.
* Gave SIGBUS a separate signal number. Fixes #6704.
* Implemented <time.h> clock and timer support, and fixed/completed alarm() and
  [set]itimer(). Closes #5682.
* Implemented support for thread cancellation. Closes #5686.
* Moved send_signal() from <signal.h> to <OS.h>. Fixes #7554.
* Lots over smaller more or less related changes.

4535495d80 Merged the signals branch into trunk, with these changes:
* The team and thread kernel structures have been renamed to Team and Thread
  respectively and moved into the new BKernel namespace.
* Several (kernel add-on) sources have been converted from C to C++ since
  private kernel headers are included that are no longer C compatible.

Changes after merging:
* Fixed gcc 2 build (warnings mainly in the scary firewire bus manager).

10f0fc8f20 * Implemented sigwait().
* Not sure if it works as intended, as the specs are a bit vague.

bc2001bb39 We have to update the pending signals thread flag when restoring the
signal block mask when returning from a signal handler.

0dd3108ca0 * Added SIGNAL_FLAG_DONT_RESTART_SYSCALL for send_signal_etc() which
utilizes the THREAD_FLAG_DONT_RESTART_SYSCALL (but only in SIGCONT
  for now).
* resume_thread() is now using that flag to be compatible with BeOS.
* This fixes the Terminal hanging on close.

df716df51d * Added is_signal_blocked() convenience function.
* Defined flag SIGNAL_FLAG_TEAMS_LOCKED for send_signal_etc(), so it can
  be called with the team lock being held.

33f0dbe40a * Resolved TODO: waitpid() clears pending SIGCHLD, if the signal is
blocked and no other child status is available.
* Respect SA_NOCLDWAIT and ignored SIGCHLD in waitpid(): Unless a child
  status is available immediately, the thread shall block until all
  children are gone.

0b70ea5992 * Implemented sigaltstack() and set_signal_stack(), thus closing bug #1401.
* On exec() the new function thread_reset_for_exec() is called which clears the signals
  and cancels an eventually set alarm. Both things weren't done before...
* Some minor cleanups.

50374cbdca Changed the signal handling code so that handle_signals() can be called without
having the thread lock held and interrupts disabled.
Cleaned up the signal handling code, and fixed some minor bugs with blockable
vs. non-blockable signals.
thread_debug_info was using uint64 for signals sets instead of sigset_t.

d4112f6bc5 Applied some changes suggested by mmu_man, more to come, though:
- has_signals_pending() is not declared in Be headers, and it isn't declared in
  our KernelExport.h anymore, too
- removed snooze_etc() from KernelExport.h, as it's already defined in OS.h
  (and really exported by libroot.so).

20b656f066 * Check the thread debug signal ignore masks before notifying the debugger
of a signal.
* Added sigaction_etc(). It's just a sigaction() for which the thread
  in question can be specified.

db75a08b98 Solved the big mystery in Ingo's life: in C, func(); and func(void); is not the same.
This fixes the "missing prototype" warnings.

782c98afd9 * Added KILL_SIGNALS, a signal mask for SIGKILL + SIGKILLTHR.
* Removed SIGKILLTHR from BLOCKABLE_SIGS.
* Made header C++ safe.
* Added function is_kill_signal_pending(), returning true, if a
  SIGKILL[THR] is pending for the current thread.

1ec1e1185b handle_signals() now takes a pointer to a cpu_state, so that after restoring and re-disabling interrupts the state can be propagated back to the caller.

383cdedbd2 Several follow-up changes required by the changes either to the VFS
syscalls or to the syscall mechanism (which exposed naming and parameter
inconsistencies).

a9731b41c1 Housekeeping changes and small bug-fixes:
Added new syscall for set_thread_priority().
Replaced the userland syscall snooze_until() with snooze_etc() (the latter
has to be exported to userland and realize snooze() and snooze_until()).
Cleaned the sources - scheduler functions now have the scheduler_ prefix.
Moved signal related stuff into ksignal.h (out of thread.h).
Replaced public kernel API with direct exports (i.e. resume_thread() instead
of thread_resume_thread()).
Removed the thread_create_XXX_thread*() calls, and replaced them with a
BeOS compatible set.
Made some fields of struct thread a bit prettier.
