Various fixes for OS X

This patch addresses compilation errors on OS X. It's been a while, so
there's quite a few things.

 * Fixed __attribute__ decls in route.h to be portable.
 * Fixed htonll and ntohll to work when they are defined as macros.
 * Replaced sem_t usage with our ast_sem wrapper.
 * Added ast_sem_timedwait to our ast_sem wrapper.
 * Fixed some GCC 4.9 warnings using sig*set() functions.
 * Fixed some format strings for portability.
 * Fixed compilation issues with res_timing_kqueue (although tests still fail
   on OS X).
 * Fixed menuconfig /sbin/launchd detection, which disables res_timing_kqueue
   on OS X).
