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.

findstring is defined as $(findstring FIND,IN) so if multiple flags are
set these tests do the wrong thing unless $(MAKEFLAGS) is the second
argument.

We have already called strlen() on "path" by the time we get here, so we
know it can't be null.

parse_configfile() takes a "const char *" and doesn't hold any
references to it after it returns; there is no reason to pass it a
duplicate.

Everywhere else in this function we do not check whether the value is
null and parse_configfile() never passes a null value to this callback.

The about page used to display just fine, but images were broken: The
binary image data was embedded in html code.
Use cgit_print_plain() to send images in plain mode and make them
available on about page.

The previous commit removed the "pre" field from "struct cgit_cmd" but
forgot to update this macro.

Most errors we generate are (potentially) transient, such as
non-existent object IDs so we don't want them to be cached forever.

This also allows us to return proper HTTP error codes when the requested
tree is not found and display an error message in one case (invalid path
inside valid commit) where we previously just displayed an empty page.
