portable: configure: split out dependencies
Rather than assume all dependencies are required for all programs, split
them out.
This will make packaging easier, as well as splitting the code to use
subprojects.
Note that due to the use of config.h semantics, in most cases the
got_compat.h header file is now at the top of the .c file it is included
in, so that it can handle the system header inclusion properly.

fix gotd sometimes reading reused deltas from wrong pack file
The reuse-pack is pinned but may change its cache slot while objects
are being deltified. Refresh the pointer to the pinned reuse-pack before
writing out the pack file, ensuring that reused deltas will in fact be
read from the reuse-pack and not some other pack. Otherwise gotd may send
a broken pack file, or hit an ERR_RANGE condition if the pack file which
now occupies the pinned-pack's old cache slot is shorter. Which can trigger
attempts to read beyond end-of-file which show up in the logs like this:
gotd[37311]: repo_read /var/git/got.git: sending packfile: value out of range
gotd[43877]: uid 1002: value out of range
gotd[43877]: uid 1002: disconnecting

add some helper functions to compute hashes
This adds a set of functions to abstract over SHA1Init, SHA1Update,
SHA1Final, their respective SHA256 variants and how to compare digests.
Replace all the SHA1*() usage with the new APIs. It's a preparatory
step for sha256 handling.

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()

make got_pack_create() write to a file descriptor instead of a stdio FILE

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.
