For some time now sha1 is considered broken and upstream is working to
replace it with sha256. Replace all references to 'sha1' with 'oid',
just as upstream does.

A previous commit changed ->tree to ->maybe_tree throughout, which may
have worked at the time, but wasn't safe, because maybe_tree is loaded
lazily. This manifested itself in crashes when using the "follow" log
feature. The proper fix is to use the correct contextual accessors
everytime we want access to maybe_tree. Thankfully, the commit.cocci
script takes care of creating mostly-correct patches that we could then
fix up, resulting in this commit here.

* treewide: rename tree to maybe_tree
(891435d55da80ca3654b19834481205be6bdfe33)
The changed data types required some of our own functions to be converted
to struct object_id:
ls_item
print_dir
print_dir_entry
print_object
single_tree_cb
walk_tree
write_tree_link
And finally we use new upstream functions that were added for
struct object_id:
hashcpy -> oidcpy
sha1_to_hex -> oid_to_hex

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.

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
to cmd_main, it is called from main then.

Update to git version v2.7.0.
* Upstream commit ed1c9977cb1b63e4270ad8bdf967a2d02580aa08 (Remove
get_object_hash.) changed API:
Convert all instances of get_object_hash to use an appropriate
reference to the hash member of the oid member of struct object.
This provides no functional change, as it is essentially a macro
substitution.

Teach the "log" UI to behave in the same way as "git log --follow", when
given a suitable instruction by the user. The default behaviour remains
to show the log without following renames, but the follow behaviour can
be activated by following a link in the page header.
Follow is not the default because outputting merges in follow mode is
tricky ("git log --follow" will not show merges). We also disable the
graph in follow mode because the commit graph is not simplified so we
end up with frequent gaps in the graph and many lines that do not
connect with any commits we're actually showing.
We also teach the "diff" and "commit" UIs to respect the follow flag on
URLs, causing the single-file version of these UIs to detect renames.
This feature is needed only for commits that rename the path we're
interested in.
For commits before the file has been renamed (i.e. that appear later in
the log list) we change the file path in the links from the log to point
to the old name; this means that links to commits always limit by the
path known to that commit. If we didn't do this we would need to walk
down the log diff'ing every commit whenever we want to show a commit.
The drawback is that the "Log" link in the top bar of such a page links
to the log limited by the old name, so it will only show pre-rename
commits. I consider this a reasonable trade-off since the "Back" button
still works and the log matches the path displayed in the top bar.
Since following renames requires running diff on every commit we
consider, I've added a knob to the configuration file to globally
enable/disable this feature. Note that we may consider a large number
of commits the revision walking machinery no longer performs any path
limitation so we have to examine every commit until we find a page full
of commits that affect the target path or something related to it.

This will allow us to introduce a new "stat only" diff mode without
needing an explosion of mutually incompatible flags.
The old "ss" query parameter is still accepted in order to avoid
breaking saved links, but we no longer generate any URIs using it;
instead the new "dt" (diff type) parameter is used.

There were many places where the arguments to a printf-like function did
not match the format string. Mostly, these were a missing 'l' flag, but
there were three exceptions:
- In ui-stats.c, a size_t argument must be printed. C99 has the "%zu"
flag for this purpose, but not all compilers support this. Therefore,
we mimic what git does - use a NO_C99_FORMAT Makefile variable.
- In ui-stats.c, cgit_print_error() was called with a pointer instead of
a character.
- In ui-log.c, the "columns" argument was never used.
