In the async code for MacOS/X define _XOPEN_SOURCE (if not already defined) as early as possible. We must do this before including any header files, because on MacOS/X <stlib.h> includes <signal.h> which includes <ucontext.h>. If we delay defining _XOPEN_SOURCE and include <ucontext.h> after various system headers are included, we are very likely to end up with the wrong (truncated) definition of ucontext_t. Also, better error handling and some code cleanup in POSIX fibre construction and destruction. We make sure that async_fibre_makecontext() always initializes the fibre to a state that can be freed. For all implementations, check for error returns from async_fibre_makecontext(). Reviewed-by: Matt Caswell <matt@openssl.org>
