fe36f84d84 ui-summary: Disallow directory traversal
Using the url= query string, it was possible request arbitrary files
from the filesystem if the readme for a given page was set to a
filesystem file. The following request would return my /etc/passwd file:

http://git.zx2c4.com/?url=/somerepo/about/../../../../etc/passwd
http://data.zx2c4.com/cgit-directory-traversal.png

This fix uses realpath(3) to canonicalize all paths, and then compares
the base components.

This fix introduces a subtle timing attack, whereby a client can check
whether or not strstr is called using timing measurements in order
to determine if a given file exists on the filesystem.

This fix also does not account for filesystem race conditions (TOCTOU)
in resolving symlinks.

cd4c77d989 readme: Accept multiple candidates and test them.
The readme variable may now contain multiple space deliminated entries,
which per usual are either a filepath or a git ref filepath. If multiple
are specified, cgit will now select the first one in the list that
exists. This is to make it easier to specify multiple default readme
types in the main cgitrc file and have them automatically get applied to
each repo based on what exists.

c2b79dd8e0 Makefile: fix parallel "make test"
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.

8d07ad3388 t0001: validate Git -rcN version numbers correctly
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.

9a725f4f09 scan-tree: fix regression in section-from-path=-1
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.

d483e8f569 t0001: ignore ".dirty" suffix on Git version
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.

31f56fc1ec tests: set TEST_OUTPUT_DIRECTORY to the CGit test directory
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.

fb3655df3b use struct strbuf instead of static buffers
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.

b1f17f168b Fix out-of-bounds memory accesses with virtual_root=""
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.
