Valgrind says:
==18344== Conditional jump or move depends on uninitialised value(s)

==18344== Uninitialised value was created by a stack allocation
==18344== at 0x40738B: cache_ls (cache.c:375)
This is caused by the keylen field being used to calculate whether or
not a slot is matched. We never then check the value of this and the
length of data read depends on the key length read from the file so this
isn't dangerous, but it's nice to avoid branching based on uninitialized
data.

When outputting the Content-Type HTTP header we print the MIME type and
then append "; charset=<charset>" if the charset variable is non-null.
We don't want a charset when we have selected "application/octet-stream"
or when the user has specified a custom MIME type, since they may have
specified their own charset. To avoid this, make sure we set the page's
charset to NULL in ui-plain before we generate the HTTP headers.

When building the "test" target we depend on both cgit and building the
Git tools. By doing this with two targets we end up running make in the
git/ directory twice, concurrently if using parallel make, which causes
us to build more than we need and potentially builds incorrectly if
multi-step build-then-move operations overlap.
Fix this by instead calling back into the makefile so that we alter the
"cgit" target to also build the Git tools.

When creating the GIT-VERSION-FILE that we use to test that the version
of Git in git/ is the same as in the CGit Makefile, Git applies the
transform "s/-/./g" to the version string. This doesn't affect released
versions but does change RC version numbers such as 1.8.3-rc0.
While CGit should only refer to a released Git version in general, it is
useful to developers who want to test upcoming Git releases if the tests
do work with RCs, so change t0001 to apply the same transform to our
Makefile version before comparing it to the contents of
GIT-VERSION-FILE.

Commit fb3655d (use struct strbuf instead of static buffers -
2013-04-06) introduced a regression in the "section-from-path" handling
when the configured value is negative. By changing the "rel" variable
so that it includes a trailing slash, counting slashes from the end of
the string no longer gives the same answer as it did before.
Fix this by ensuring that "rel" does not have a trailing slash.

When testing modifications in Git that affect CGit, it is annoying to
have t0001 failing simply because the Git version has a ".dirty" suffix
when the version of Git there does indeed match that specified in the
CGit makefile. Stop this by stripping the ".dirty" suffix from the
GIT_VERSION variable.
Note that this brings the "Git version" behaviour in line with the
"submodule version" case which does not check if the working tree in
git/ is modified.

By default, Git's test suite puts the trash directories and test-results
directory into its own directory, not that containing the tests being
run. This is less convenient for inspecting test failures, so set the
output directory to CGit's tests/ directory instead.
Note that there is currently a bug in Git whereby it will create the
trash directories in our tests/ directory regardless of the value of
TEST_OUTPUT_DIRECTORY, and then fail to remove them once the tests are
done. This change does currently affect the location of the
test-results/ directory though.

This allows tests to run in parallel as well as letting us use "prove"
or another TAP harness to run the tests.
Git's test framework requires Git to be fully built before letting any

that.

Use "struct strbuf" from Git to remove the limit on file path length.
Notes on scan-tree:
This is slightly involved since I decided to pass the strbuf into
add_repo() and modify if whenever a new file name is required, which
should avoid any extra allocations within that function. The pattern
there is to append the filename, use it and then reset the buffer to its
original length (retaining a trailing '/').
Notes on ui-snapshot:
Since write_archive modifies the argv array passed to it we
copy the argv_array values into a new array of char* and then free the
original argv_array structure and the new array without worrying about
what the values now look like.

The CGit configuration variable virtual_root is normalized so that it
does not have a trailing '/' character, but it is allowed to be empty
(the empty string and NULL have different meanings here) and there is
code that is insufficiently cautious when checking if it ends in a '/':
if (virtual_root[strlen(virtual_root) - 1] != '/')
Clearly this check is redundant, but rather than simply removing it we
get a slight efficiency improvement by switching the normalization so
that the virtual_root variable always ends in '/'. Do this with a new
"ensure_end" helper.

Git calculates the dependency files to be included using a simply

If CGIT_VERSION is in CGIT_CFLAGS then a change in version (for example

Git does quite a lot of platform-specific detection in its Makefile,
which can result in it defining preprocessor variables that are used in
its header files. If CGit does not define the same variables it can
result in different sizes of some structures in different places in the
same application.
For example, on Solaris Git uses it's "compat" regex library which has a
different sized regex_t structure than that available in the platform
regex.h. This has a knock-on effect on the size of "struct rev_info"
and leads to hard to diagnose runtime issues.
In order to avoid all of this, introduce a "cgit.mk" file that includes
Git's Makefile and make all of the existing logic apply to CGit's
objects as well. This is slightly complicated because Git's Makefile
must run in Git's directory, so all references to CGit files need to be
prefixed with "../".
In addition, OBJECTS is a simply expanded variable in Git's Makefile so
we cannot just add our objects to it. Instead we must copy the two
applicable rules into "cgit.mk". This has the advantage that we can
split CGit-specific CFLAGS from Git's CFLAGS and hence avoid rebuilding
all of Git whenever a CGit-specific value changes.

When a repository is empty, the ATOM feed link is written in the header,
but this involves formatting ctx->qry.head which is NULL in this case.
With glibc, vsnprintf formats "%s" with a NULL input as "(null)" but on
Solaris this results in a segmentation fault. Since we don't have a
meaningful head for the atom feed in an empty repository, it's simplest
not to write out the link element at all.
