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.

- Date:
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.

provide functions to parse/serialize different hashes
it abstracts over the hash type and ensures that object ids are zero'ed
before their sha1 digest is written. Needed by the incoming sha256
support.

rename lib/sha1.c to lib/hash.c
It will soon grow functions to deal with sha256 too. stsp@ agrees.

include sha2.h too where sha1.h is included
In preparation for wide sha256 support; stsp@ agrees. Change done
mechanically with

introduce got_object_id_hex to replace some got_sha1_digest_to_str()
It's an analogous to got_object_id_str but writes to the given buffer.

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.
