expose out-of-memory errors from zlib inflate() and deflate() calls
Previously these were hidden behind a general "compression failed" error.

remove now unused sha1 handling from inflate and deflate

- 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.

include sha2.h too where sha1.h is included

zero-initialize all of struct got_deflate_buf in got_deflate_init()
Fixes a potential bogus free on error.
got_deflate_end() relies on zb.flags to be initialized. It will try to free
a bogus zb.outbuf pointer if zb.flags happens to set by uninitialized stack
memory while we are calling got_deflate_end() in an error path.

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.

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.

fix infinite loop in got-index-pack for pack files >= 4GB in size
Because of a missing range check our zlib wrapper would end up
calling zlib over and over with zero bytes of input.
Problem reported by semarie and naddy.
Fixed with help from millert@.

- Date:
add checksum support to got_deflate_to_file()
This will eventually be used by 'gotadmin pack'.
Checksum init and finalization will need to be done by the caller
since many objects will be written out in compressed form while
we are computing checksums across the entire pack file.

also add got_error_prefix_errno2 and got_error_prefix_errno3 which
should hopefully all be merged into a single function with variadic
args (but can't alloc mem)
