introduce gotd(8), a Git repository server reachable via ssh(1)
This is an initial barebones implementation which provides the absolute
minimum of functionality required to serve got(1) and git(1) clients.
Basic fetch/send functionality has been tested and seems to work here,
but this server is not yet expected to be stable.
More testing is welcome. See the man pages for setup instructions.
The current design uses one reader and one writer process per repository,
which will have to be extended to N readers and N writers in the future.
At startup, each process will chroot(2) into its assigned repository.
This works because gotd(8) can only be started as root, and will then
fork+exec, chroot, and privdrop.
At present the parent process runs with the following pledge(2) promises:
"stdio rpath wpath cpath proc getpw sendfd recvfd fattr flock unix unveil"
The parent is the only process able to modify the repository in a way
that becomes visible to Git clients. The parent uses unveil(2) to
restrict its view of the filesystem to /tmp and the repositories
listed in the configuration file gotd.conf(5).
Per-repository chroot(2) processes use "stdio rpath sendfd recvfd".
The writer defers to the parent for modifying references in the
repository to point at newly uploaded commits. The reader is fine
without such help, because Git repositories can be read without
having to create any lock-files.
gotd(8) requires a dedicated user ID, which should own repositories
on the filesystem, and a separate secondary group, which should not
have filesystem-level repository access, and must be allowed access
to the gotd(8) socket.
To obtain Git repository access, users must be members of this
secondary group, and must have their login shell set to gotsh(1).
gotsh(1) connects to the gotd(8) socket and speaks Git-protocol
towards the client on the other end of the SSH connection.
gotsh(1) is not an interactive command shell.
At present, authenticated clients are granted read/write access to
all repositories and all references (except for the "refs/got/" and
the "refs/remotes/" namespaces, which are already being protected
from modification).
While complicated access control mechanism are not a design goal,
making it possible to safely offer anonymous Git repository access
over ssh(1) is on the road map.

move got_opentempfd() call out of got_pack_create()
Future gotd(8) needs to run got_pack_create() in a chroot environment,
so we can no longer open new temporary files inside got_pack_create().

make got_pack_create() write to a file descriptor instead of a stdio FILE
The old code required a seekable output file. This conflicts with requirements
of future gotd(8), which will write pack file data to network sockets.

portable: add back sys/queue.h
Now that the handling of including sys/queue.h is better, there's no
need to remove those lines from the source. Copy the location of those
original sys/queue.h lines from upstream at the same line number, so as
to avoid any conflicts in the future.

revert object enumeration in got-read-pack for now; needs more work
This implementation marked commits and trees as enumerated before all trees
which they depend on were enumerated. This behaviour leads to incomplete
pack files when a tree is only partially packed and got-read-pack hits
a missing tree entry as a result. The algorithm must be reworked such
that packed leave nodes are marked enumerated first, then bubble-up.

fix a bug in findwixt() which caused pack files with missing parent commits
The 'nskip' variable is supposed to reflect commits which are waiting on
the queue and have the 'skip' color. Only increment 'nskip' when adding
such commits to the queue.
Problem observed with got send -T and a tag pointing to a deleted branch.
Test to reproduce the bug written by op@.
