Port to Solaris 8.

Without this change, 'configure' fails because the recently-added
wait3 prototype in config.h messes up later 'configure' tests.
Fix this problem by droping wait3 and WRETCODE, as they're
no longer needed on hosts that are current porting targets.
* configure.ac (wait3, WRETCODE): Remove, fixing a FIXME.
All uses changed to waitpid and WEXITSTATUS.
* src/syswait.h (WRETCODE): Remove, consistently with ../configure.ac.

Avoid needless autoheader after autogen.sh.
* src/stamp-h.in: Remove from bzr repository; no longer needed there.
* .bzrignore: Add it.
