By specifying the "url" query parameter multiple times it is possible to
end up with ctx.qry.vpath set while ctx.repo is null, which triggers an
invalid code path from cgit_print_pageheader() while printing path
crumbs, resulting in a null dereference.
The previous patch fixed this segfault, but it makes no sense for us to
clear ctx.repo while leaving ctx.qry.path set to the previous value, so
let's just clear it here so that the last "url" parameter given takes
full effect rather than partially overriding the effect of the previous
value.

cgit_print_path_crumbs() can call repolink() which assumes that ctx.repo
is non-null. Currently we don't have any commands that set want_vpath
without also setting want_repo so it shouldn't be possible to fail this
test, but the check in cgit.c is in the wrong order so it is possible to
specify a query string like "?p=log&path=foo/bar" to end up here without
a valid repository.

If the delimiter here is '&' then it needs to be escaped for inclusion
in an attribute. Use html_attrf() to ensure that this happens (we know
that hex won't need escaping, but this makes it clearer what's
happening.

Numerous changes were made to git functions to use an object_id
structure rather than sending sha1 hashes as raw unsigned character
arrays. The functions that affect cgit are: parse_object,
lookup_commit_reference, lookup_tag, lookup_tree, parse_tree_indirect,
diff_root_tree_sha1, diff_tree_sha1, and format_display_notes.
Commit b2141fc (config: don't include config.h by default) made it
necessary to that config.h be explicitly included when needed.
Commit 07a3d41 (grep: remove regflags from the public grep_opt API)
removed one way of specifying the ignore-case grep option.

Update to git version v2.13.4: With commit 8aee769f (pathspec: copy and free
owned memory) the definition of struct pathspec_item has changed with the
expectation that pathspecs will be managed dynamically. We work around this
a bit by setting up a static structure, but let's allocate the match string
to avoid needing to cast away const.
Updated a patch from John Keeping <john@keeping.me.uk> for git v2.12.1.

When empty repos exist, comparing them against an existing repo with a
good mtime might, with particular qsort implementations, not sort
correctly, because of this brokenness:
if (get_repo_modtime(r1, &t) && get_repo_modtime(r2, &t))
However, sorting by the age column works as expected, so anyway, to tidy
things up, we simply reuse that function.

This was originally applied added in commit eac1b67 (ui-patch: Apply
path limit to generated patch, 2010-06-10) but the ability to limit
patches to particular paths was lost in commit 455b598 (ui-patch.c: Use
log_tree_commit() to generate diffs, 2013-08-20).
The new output is slightly different from the original because Git's
diff infrastructure doesn't give us a way to insert an annotation
immediately after the "---" separator, so the commit has moved below the
diff stat.

Instead of reimplementing URL parameter parsing from scratch, use
url_decode_parameter_name() and url_decode_parameter_value() which are
already provided by Git.
Also, change the return type of http_parse_querystring() to void since
its only caller already ignores the return value.

As libgit.a moves away from using fixed size buffers, there is no
guarantee that PATH_MAX is sufficient for all of the paths in a Git
tree, so we should use a dynamically sized buffer here.

Currently we can end up passing EOF to isspace(), which is in fact
libgit's sane_isspace which does:
((sane_ctype[(unsigned char)(x)] & (GIT_SPACE)) != 0)
It is very unlikely that EOF cast to "unsigned char" will end up in a
character that has the GIT_SPACE bit set, but the standard only requires
that EOF be a negative integer, so it could access any value in the
sane_ctype array.
If it does end up returning true for isspace() then this loop will never
terminate, so handle EOF as a special value in the same way as the other
loops in this function.

Upstream continues to replace unsigned char *sha1 with struct
object_id old_oid. This makes the required changes.
The git lib has its own main function now. Rename our main function
