By moving got_serve_parse_command() from lib/serve.c into lib/dial.c as got_dial_parse_command(), we can significantly reduce the amount of symbols gitwrapper depends on indirectly. As a downside, gotsh now needs to link to dial.c. But it only uses the same parsing routine, and any other routines in dial.c would likely cause pledge violations in gotsh if used. No functional change.

gotd still requires the config file, of course, but gitwrapper must treat is as optional and remain silent if the file cannot be found.

Since we're going to unconditionally execute gotsh or git-*-pack, don't bother fork()ing and having the main process to wait(2), just execle()! ok stsp@
