libxml2: security bump to version 2.9.3

- Fixes:
  - CVE-2015-5312 - Another entity expansion issue
  - CVE-2015-7497 - Avoid an heap buffer overflow in xmlDictComputeFastQKey
  - CVE-2015-7500 - Fix memory access error due to incorrect entities boundaries
  - CVE-2015-8242 - Buffer overead with HTML parser in push mode

- Incorporates upstreamed patches as well, which also fixed:
  - CVE-2015-1819 - The xmlreader in libxml allows remote attackers to cause
    a denial of service (memory consumption) via crafted XML data, related
    to an XML Entity Expansion (XEE) attack.
  - CVE-2015-7941 - out-of-bounds memory access.
  - CVE-2015-7942 - heap-buffer-overflow in xmlParseConditionalSections.
  - CVE-2015-8035 - DoS via crafted xz file.

-Subject: threads: use forward declarations only for glibc
-
-Fixes bug #704908
-
-The declarations of pthread functions, used to generate weak references
-to them, fail to suppress macros. Thus, if any pthread function has
-been provided as a macro, compiling threads.c will fail.
-This breaks on musl libc, which defines pthread_equal as a macro (in
-addition to providing the function, as required).
-
-Prevent the declarations for e.g. musl libc by refining the condition.
-
-The idea for this solution was borrowed from the alpine linux guys, see
-http://git.alpinelinux.org/cgit/aports/tree/main/libxml2/libxml2-pthread.patch
