move code for reading Git's config file into new file read_gitconfig_privsep.c The end goal here is to remove the dependency of repository.c on privsep.c during compilation.

add gotadmin init -b <branch> to specify repo head ref Similar to `git init -b`. Includes a change to `got import` behaviour such that "main" is no longer hardcoded by default; instead, we import to the branch resolved via the repository's HEAD reference unless `got import -b` is used, and only if HEAD cannot be resolved to a branch do we fallback to "main". includes fix plus ok from stsp@

free the return of got_repo_get_path_objects{,_pack}

plug mem leak in got_repo_pack_fds_open pack_fds_tmp is not always free'd. However, while here, simplify it to not use a temporary array. ok stsp@

plug a leak in match_loose_object in the loop of match_loose_object we allocate a string per directory entry that in some case it was free(3)'d before `continue' or `goto', but not always. Instead, use a more common idiom. ok stsp@

refresh our pack-index path list if the mtime of objects/pack has changed ok op@

don't leak memory allocated internally by bloom filters; ok jamsek

remove trailing whitespace; patch by Josiah Frentsos

read_gitconfig: fix GOT_IGNORE_GITCONFIG case set gitconfig_remotes to NULL to avoid a double-free, and reset the global author name/email fields too. ok stsp@

add a way to ignore author and remote repository info found in Git config files ok op@

comment tweak

got_repo_pack_fds_close: don't close(0) got_repo_pack_fds_close will try to close all of the GOT_PACK_NUM_TEMPFILES fds, even the ones that didn't manage to get a value from got_opentempfd(), which would result in a close(0) if we do not initialize to -1 here.

Make sure got_repo_pack_fds_close() frees a malloc'ed pointer. Found by llvm's scan-build (bad free). OK stsp

Don't chug along if repo format version is unsupported. Found by llvm's scan-build (dead store). OK stsp

implement support for commit coloring in got-read-pack for speed ok op, tracey
