Solved the big mystery in Ingo's life: in C, func(); and func(void); is not the same. This fixes the "missing prototype" warnings. git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11627 a95241bf-73f2-0310-859d-f6bbb57e9c96

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. git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2569 a95241bf-73f2-0310-859d-f6bbb57e9c96

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. git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11309 a95241bf-73f2-0310-859d-f6bbb57e9c96

Changed the signal handling code so that handle_signals() can be called without having the thread lock held and interrupts disabled.

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). git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12506 a95241bf-73f2-0310-859d-f6bbb57e9c96
