As per stsp's idea: use a more descriptive name, and use the TOG_TEST_SCRIPT envvar both in tog.c and the test scripts. ok stsp@

Move some functions from object_parse.c into hash.c. These functions either require hash.c code anyway or contain object ID implementation internals. Add a new file object_qid.c, for got_object_id_queue and got_object_qid. This new file must be linked to virtually every program.

Move gotd_auth_parseuid() from auth.c to parse.y as gotd_parseuid(), and remove auth.c from the list of source files required by gitwrapper.

Move gotd_find_uid_connection_limit() from listen.c into parse.y and remove listen.c from the list of source files required by gitwrapper.

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.

This enables running of the tog regress tests. Note that this is enabled before regress-cmdline, as regress-cmdline takes a while.

On some systems libmd isn't explicitly implied, so detect this via pkg-config at configure time. Problem reported by @stsp

Otherwise we leave unversioned files behind in the work tree which may interfere with new attempts to rebase or merge the changes again. Problem found by + ok naddy@

Since standard error is unbuffered, it could happen that the error string is printed immediately while the output from the subcommand is stuck in a buffer and written later. So flush() standard output before printing the error message. Problem reported by naddy@, ok stsp@
