Modernize: use sigaction() whenever possible. Remove uses of common.

Browse source 
bsd_signal() may not be defined, and there is really no reason to even
try to use it if sigaction() is avaiable; using sigaction() guarantees
the semantics we really want.

Replace uses of common variables with explicit instantiation and
extern declarations in a header file.
