Release of libxml2-2.9.12
Brown paper bag release, some recently added sources were missing from
the 2.9.11 tarball:
- configure.ac: bump version
- fuzz/Makefile.am: add fuzz.h and seed/regexp to EXTRA_DIST

Release of libxml2-2.9.11
Prompted by CVE-2021-3541, but this includes an awful lot of serious bug
fixes by Nick and others.
- configure.ac: bumped to new release
- doc/* updated and regenerated

Patch for security issue CVE-2021-3541
This is relapted to parameter entities expansion and following
the line of the billion laugh attack. Somehow in that path the
counting of parameters was missed and the normal algorithm based
on entities "density" was useless.

-Subject: [PATCH] Parenthesize Py<type>_Check() in ifs
-
-In C, if expressions should be parenthesized.
-PyLong_Check, PyUnicode_Check etc. happened to expand to a parenthesized
-expression before, but that's not API to rely on.
-
-Since Python 3.9.0a4 it needs to be parenthesized explicitly.
-
-Fixes https://gitlab.gnome.org/GNOME/libxml2/issues/149
