We abuse the "void *util" field as a counter and recently started to
cast it to a uintptr_t to avoid risking nasal demons by performing
arithmetic on a void pointer.
However, compilers are also known to do "interesting" things if they
know that a pointer is or isn't NULL. Make this safer by checking if
the counter (after casting) is non-zero rather than checking if the
pointer is non-null.

This affects the tooltip showing the full time and the case when a date
is sufficiently old to be shown in full rather than as an offset.

This returns the correct mode value for use with Git's show_date() based
on the current CGit configuration and will be used in the following
patches.

This will allow us to mimic Git's behaviour of showing times in the
originator's timezone when displaying commits and tags.

We call open_slot() from cache_ls() without a key since we simply want
to read the path out of the header. Should the file happen to contain
an empty key then we end up calling memcmp() with NULL and a non-zero
length. Fix this by assigning slot->match only if a key is set, which
is always will be in the code paths where we use slot->match.

If parse_commit() fails, none of the fields in the commit structure will
have been populated so we will dereference NULL when accessing
item->tree.
There isn't much we can do about the error at this point, but if we
return true then we'll try parsing the commit again from print_commit()
and we can report an error to the user at that point.

Return HTTP status code 404 Not found when querying a non-existent
repository, which signals to search engines that a repository no
longer exists. Further, some webservers such as nginx permit
logging requests to different files depending on the HTTP code.

The ctx.qry.page variable might be unset at this point, e.g. when an
invalid command is passed and cgit_print_pageheader() is called to show
an error message.

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.

readfile() can fail if the agefile is not readable. Make sure free()
does not free an ininitialized string.

ctx.env.content_length is an unsigned int, coming from the
CONTENT_LENGTH environment variable, which is parsed by strtoul. The
HTTP/1.1 spec says that "any Content-Length greater than or equal to
zero is a valid value." By storing this into an int, we potentially
overflow it, resulting in the following bounding check failing, leading
to a buffer overflow.
