libxml2: Update to version 2.14.0

libxml2: Update to version 2.14.0

- Update from version 2.13.5 to 2.14.0
- Update of rootfile
- sobump so ran find-dependencies. apache2, clamav, collectd, libvirt, libxslt, nfs,
   rng-tools, rrdtool and tshark are all linked against the lib bump. So additional
   patches are in this set to bump the PAK_VER and ship the addons and to ship the
   linkied core packages. Hope it is done correctly. Let me know if not.
- 2 CVE fixes added into version 2.13.6
- Changelog
    2.14.0
      Major changes
	The HTML tokenizer now conforms fully to HTML5. Several non-standard
	 syntax warnings were removed. Note that HTML5 tree construction isn't
	 implemented yet.
	Binary compatibility is restricted to versions 2.14 or newer. On ELF
	 systems, the soname was bumped from libxml2.so.2 to libxml2.so.16.
	The serialization API will now take user-provided or default encodings
	 into account when serializing attribute values, matching the
	 serialization of text and avoiding unnecessary escaping.
	The XML parser won't try to merge consecutive CDATA sections as before
	 to align with web standards. Each CDATA section will create exactly one
	 node or SAX callback.
	Support for RELAX NG can now be disabled with a new configuration
	 option independently of XML Schemas support. It is still enabled by
	 default.
	The "legacy" configuration option won't enable support for HTTP and
	 LZMA anymore. These features will be removed in the next release.
	Parts of the xmllint executable were refactored, allowing the
	 combination of more options. OOM errors should be reported reliably now.
	Several improvements were made to the build systems. Meson is fully
	 supported now.
	Parts of the buffering code were reworked and simplified.
	Overflow checks before reallocations were hardenend.
	Some unprefixed symbols were renamed to avoid namespace pollution.
      New features
	Input callbacks can now be set on a parser context and an improved API
	 to create parser input is available. The following new functions,
	 taking a parser input object, were added:
		- xmlCtxtParseDocument
		- xmlCtxtParseContent as replacement for xmlParseBalancedChunkMemory
		  and xmlParseInNodeContext
		- xmlCtxtParseDtd
	The xmlSave API now has additional options to replace global settings.
	Parser options XML_PARSE_UNZIP, XML_PARSE_NO_SYS_CATALOG and
	 XML_PARSE_CATALOG_PI were added.
	An API function to install a custom character encoding converter is
	 now available. This makes it possible to use ICU for encoding conversion
	 even if libxml2 was compiled without ICU support, see example/icu.c.
      Deprecations
	Access to many public struct members is now deprecated. Several accessor
	 functions were added to use instead.
	More internal functions were deprecated.
      Removals
	Metadata about the HTML4 content model was removed from the htmlElemDesc
	 struct and related functions were deprecated.
	The FTP module and related functions were removed.
	Support for the range and point extensions of the xpointer() scheme
	 was removed. The rest of the XPointer implementation isn't affected.
	 The xpointer() scheme now behaves like the xpath1() scheme.
	Several legacy symbols and the functions in xmlunicode.h were removed.
	ELF version information was removed.
	The shell was moved from libxml2 to xmllint. Several related functions
	 are no longer available.
	The libxml.m4 file containing autoconf macros was removed.
	The --with-tree configuration option was removed.
	The hack to detect single-threaded programs under glibc was removed.
      Planned removals
	Support for HTTP and LZMA compression is planned to be removed in the
	 2.15 release.
	The following features are considered for removal:
		- Modules API (xmlmodule.h)
		- Schematron support
		- Support for zlib compressed file I/O
		- Legacy Windows build system in win32
	RELAX NG support is still in a bad state and a long-term removal
	 candidate.
