Typo.

posix_spawn_file_actions_adddup2(3): Document difference with dup2().

posix_spawn_file_actions_adddup2() is in fact proposed in Austin Group issue
#411.

posix_spawn_file_actions_addopen(3): Correct error for bad file descriptor.

As per POSIX.1-2008, posix_spawn_file_actions_add* return [EBADF] if a file
descriptor is negative, not [EINVAL]. The bug was only in the manual page;
the code is correct.

Fix the email address formats in some posix_spawn(3) manpages.

It seems I made a small bug when writing some of the posix_spawn(3)
manpages. Remove the redundant "Ed Schouten", which broke the AUTHORS
section.
