There's a flaw in libxml2 in versions before 2.9.11. An attacker who is able to submit a crafted file to be processed by an application linked with libxml2 could trigger a use-after-free. The greatest impact from this flaw is to confidentiality, integrity, and availability.

Reformatted runtest.patch to allow it to be applied using git am.
This makes it easier to apply the series of patches to the original git repo.
There are no changes to the code of the patch other than the reformat.
Previously, the patch claimed to be a backport, but I have not found an
upstream commit so I've changed the Upstream-Status to pending.

Fix nullptr deref with XPath logic ops
If the XPath stack is corrupted, for example by a misbehaving extension
function, the "and" and "or" XPath operators could dereference NULL
pointers. Check that the XPath stack isn't empty and optimize the
logic operators slightly.

The patch tool will apply patches by default with "fuzz", which is where if the
hunk context isn't present but what is there is close enough, it will force the
patch in.
Whilst this is useful when there's just whitespace changes, when applied to
source it is possible for a patch applied with fuzz to produce broken code which
still compiles (see #10450). This is obviously bad.
We'd like to eventually have do_patch() rejecting any fuzz on these grounds. For
that to be realistic the existing patches with fuzz need to be rebased and
reviewed.

We enable the python module in nativesdk-libxml2, but the python binary
used is in the native sysroot and thus you get the module installed in
the wrong path. Even with that fixed the python files are still
unpackaged, so create an ${PN}-python package and add them to it. (This
does not affect the libxml target build at all since python is disabled
for that.)

It was discovered that libxml2, a library providing support to read,
modify and write XML files, incorrectly performs entity substituton in
the doctype prolog, even if the application using libxml2 disabled any
entity substitution. A remote attacker could provide a
specially-crafted XML file that, when processed, would lead to the
exhaustion of CPU and memory resources or file descriptors.
