remove unused function got_read_file_to_mem()

remove dependency of gitwrapper, gotctl, and gotsh on object_parse.c 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.

remove dependency of gitwrapper on gotd/auth.c 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.

remove dependency of gitwrapper on gotd/listen.c 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.

significantly reduce the amount of code linked into 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.

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

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

when aborting rebase/histedit/merge, unlink files added by merged changes 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@

got: flush stdout before printing the error in main() 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@

make 'got revert' and 'got rm' work on non-existent directories problem found by robert@ ok jamsek, op

fix rebase/histedit -a leaving some files on the temporary branch The commands 'got rebase -a' and 'got histedit -a' were checking out files from the wrong commit. Make them check files out from the commit we are switching the work tree to, as intended. Avoids spurious merge conflicts when the work tree is later used for another rebase operation. It also makes 'got update' right after 'rebase -a' a no-op, as it should be. Problem found by naddy@ while rebasing jca's llvm15 branch ok op, jamsek earlier version

update the base commit ID of unmodified files if the blob ID matches This avoids having to run 'got update' after operations which run checkout_files() and where a file happens to have the same blob ID but its base commit differs from the commit we are updating to. Found while investigating a bug report by naddy@ ok op, jamsek (earlier version)

tog: implement automated test harness Add framework for scripting tog tests by capturing screen dumps to compare with expected output. Includes some preliminary log view tests but lots more tests are needed to cover diff, blame, tree, ref, and help views. ok stsp@

make gotd/gitwrapper start up even if a repository is missing on disk This should result in more useful behaviour when gitwrapper runs and repositories listed in gotd.conf do not yet exist or do no longer exist.

fix spurious empty packfile error from gotd when rewinding a branch ok op@

consistently close the struct repository on every cmd_*() Spotted while looking for leaks using Otto' malloc() new leaks detection. Harmless in practice since we just forgot to call got_repo_close() when terminating in some cmd_*() functions, but still a leak. ok stsp@

free fileindex entry upon add_entry() failure Very unlikely (an occurrence of it would mean that got produced an invalid fileindex) and harmless anyway since we would just terminate, but a leak is still a leak. ok stsp@
