b8ea3ab76a
Somewhat notable changes:
- Remove pointless test commands from Mamfiles.
- Consistent use of NoN macro instead of manual void _STUB_foo(){}
(this is to silence "foo.o has no symbols" warnings from ld).
- Remove src/lib/libast/comp/transition.c; obsolete, does nothing.
- xec.c: Fix off-by-one error in sigreset() used by sh_ntfork():
it tried to (re)set signal 0, which is harmless, but wrong.
(note that sh.st.trapmax is the current max trapped sig + one!)
