2011-03-30	avoid all malloc/free in timer creation/destruction	Rich Felker	-6/+7
	instead of allocating a userspace structure for signal-based timers, simply use the kernel timer id. we use the fact that thread pointers will always be zero in the low bit (actually more) to encode integer timerid values as pointers. also, this change ensures that the timer_destroy syscall has completed before the library timer_destroy function returns, in case it matters.
2011-03-29	reorder timer initialization so that timer_create does not depend on free	Rich Felker	-1/+1
	this allows small programs which only create times, but never delete them, to use simple_malloc instead of the full malloc.
2011-03-29	implement POSIX timers	Rich Felker	-0/+12
	this implementation is superior to the glibc/nptl implementation, in that it gives true realtime behavior. there is no risk of timer expiration events being lost due to failed thread creation or failed malloc, because the thread is created as time creation time, and reused until the timer is deleted.
