xdiff: include new xdiff from git
Update to the xdiff used in git v2.35.0, with updates to our build
configuration to ignore the sort of warnings that we normally care
about (signed/unsigned mismatch, unused, etc.)
Any git-specific abstraction bits are now redefined for our use in
`git-xdiff.h`. It is a (wildly optimistic) hope that we can use that
indirection layer to standardize on a shared xdiff implementation.

xdiff: upgrade to git's included xdiff
Upgrade xdiff to git's most recent version, which includes changes to
CR/LF handling. Now CR/LF included in the input files will be detected
and conflict markers will be emitted with CR/LF when appropriate.

xdiff/xprepare: fix a memory leak
The xdl_prepare_env() function may initialise an xdlclassifier_t
data structure via xdl_init_classifier(), which allocates memory
to several fields, for example 'rchash', 'rcrecs' and 'ncha'.
If this function later exits due to the failure of xdl_optimize_ctxs(),
then this xdlclassifier_t structure, and the memory allocated to it,
is not cleaned up.
In order to fix the memory leak, insert a call to xdl_free_classifier()
before returning.
This patch was originally written by Ramsay Jones (see commit
87f16258367a3b9a62663b11f898a4a6f3c19d31 in git.git).

xdiff/xprepare: use the XDF_DIFF_ALG() macro to access flag bits
Commit 307ab20b3 ("xdiff: PATIENCE/HISTOGRAM are not independent option
bits", 19-02-2012) introduced the XDF_DIFF_ALG() macro to access the
flag bits used to represent the diff algorithm requested. In addition,
code which had used explicit manipulation of the flag bits was changed
to use the macros.
However, one example of direct manipulation remains. Update this code to
use the XDF_DIFF_ALG() macro.
This patch was originally written by Ramsay Jones (see commit
5cd6978a9cfef58de061a9525f3678ade479564d in git.git).

xdiff: upgrade to core git 2.4.5
Upgrade xdiff to version used in core git 2.4.5 (0df0541).
Corrects an issue where an LF is added at EOF while applying
an unrelated change (ba31180), cleans up some unused code (be89977 and
e5b0662), and provides an improved callback to avoid leaking internal
(to xdiff) structures (467d348).
This also adds some additional functionality that we do not yet take
advantage of, namely the ability to ignore changes whose lines are
all blank (36617af).
