hooks: parse incoming git refs correctly
Hooks receive a line of the following format on standard input:
<old-value> SP <new-value> SP <ref-name> LF
where <old-value> is the old object name stored in the ref,
<new-value> is the new object name to be stored in the ref
and <ref-name> is the full name of the ref.
This means, we have to strip at least the LF in order to have a
correct version of the ref name after the split. Also, when
parsing the ref name itself, use all components but first instead
of just second, as a ref name may have slashes in it.
Previously, failure to parse ref name correctly would lead to the
following behaviour. A newly created repository with no commits pushed
has HEAD set to refs/heads/master by default, even though there's no
such ref in the repository yet. Upon first push, Kallithea rewrites
this symbolic reference with a reference to a real branch.
However, due to a bug in ref name parsing, if a ref name had a slash,
Kallithea would update HEAD to an invalid reference:
git push origin feature/branch
would rewrite HEAD to refs/heads/feature. All future attempts to work
with this repository would fail because dulwich would complain it can't
read HEAD as it is a directory.
