Commit d53c2c6 (mingw: fix t9700's assumption about
directory separators, 2016-01-27) uses perl's "/r" regex
modifier to do a non-destructive replacement on a string,
leaving the original unmodified and returning the result.
This feature was introduced in perl 5.14, but systems with
older perl are still common (e.g., CentOS 6.5 still has perl
5.10). Let's work around it by providing a helper function
that does the same thing using older syntax.
While we're at it, let's switch to using an alternate regex
separator, which is slightly more readable.

In contrast to apache 2.2, apache 2.4 does not load mod_unixd in its
default configuration (because there are choices). Thus, with the
current config, apache 2.4.10 will not be started and the httpd tests
will not run on distros with default apache config (RedHat type).
Enable mod_unixd to make the httpd tests run. This does not affect
distros negatively which have that config already in their default
(Debian type). httpd tests will run on these before and after this patch.

A v2 pack index file can specify an offset within a packfile
of up to 2^64-1 bytes. On a system with a signed 64-bit
off_t, we can represent only up to 2^63-1. This means that a
corrupted .idx file can end up with a negative offset in the
pack code. Our bounds-checking use_pack function looks for
too-large offsets, but not for ones that have wrapped around
to negative. Let's do so, which fixes an out-of-bounds
access demonstrated in t5313.

If a pack .idx file has a corrupted offset for an object, we
may try to access an offset in the .idx or .pack file that
is larger than the file's size. For the .pack case, we have
use_pack() to protect us, which realizes the access is out
of bounds. But if the corrupted value asks us to look in the
.idx file's secondary 64-bit offset table, we blindly add it
to the mmap'd index data and access arbitrary memory.
We can fix this with a simple bounds-check compared to the
size we found when we opened the .idx file.
Note that there's similar code in index-pack that is
triggered only during "index-pack --verify". To support
both, we pull the bounds-check into a separate function,
which dies when it sees a corrupted file.
It would be nice if we could return an error, so that the
pack code could try to find a good copy of the object
elsewhere. Currently nth_packed_object_offset doesn't have
any way to return an error, but it could probably use "0" as
a sentinel value (since no object can start there). This is
the minimal fix, and we can improve the resilience later on
top.

Our on-disk .pack and .idx files may reference other data by
offset. We should make sure that we are not fooled by
corrupt data into accessing memory outside of our mmap'd
boundaries.
This patch adds a series of tests for offsets found in .pack
and .idx files. For the most part we get this right, but
there are two tests of .idx files marked as failures: we do
not bounds-check offsets in the v2 index's extended offset
table, nor do we handle .idx offsets that overflow a signed
off_t.
With these tests, we should have good coverage of all
offsets found in these files. Note that this doesn't cover
.bitmap files, which may have similar bugs.
