(sos_alloc): If HAVE_CMPXCHG is defined, use cmpxchg_ptr() to atomically allocate
	memory in a lock-free manner.  Otherwise, fall back on disabling signal
	delivery and holding the sos_lock during memory allocation.
(sos_free): Remove.
(mempool_init): Initialize pool lock.  Replace LOCK/UNLOCK with appropriate
	signal-masking & mutex_lock/unlock calls.

62491cc719 Many fixes to get (remote) dynamic unwind info working for real. 
Add get_proc_name() callback to accessors so things like the ptrace-support
routines can also print static procedure names.
Try running "tests/test-ptrace -v -t tests/ia64-test-dyn1" for fun.

4577631094 Don't be verbose by default. 
(main): Send SIGUSR1 before dynamic testing starts, SIGUSR2 afterwards (makes it

1fc6f4e6b3 (unwi_dyn_remote_find_proc_info): If anything goes wrong, return -UNW_ENOINFO. 
Skip over "prev_addr".  Read start/end-IP directly into the "di" structure,
	not into temporary variables.  Skip padding by directly adjusting the
	address (don't bother fetching padding values; that only slows things down).
	Return 0 only if we really did find dynamic unwind info.
