Split posix_spawn.c into 3 different files
posix_spawnattr.c
posix_spawn_file_actions.c
posix_spawn.c
Also, move the declarations of the posix_spawn types
into spawn.h.
These two changes combined allow alternative
implementations of posix_spawn to be provided without
duplicating the posix_spawnattr* and
posix_spawn_file_actions* functions.
