Add missing increments of recursion depth counter to XML parser.
For https://bugzilla.gnome.org/show_bug.cgi?id=765207
CVE-2016-3705
The functions xmlParserEntityCheck() and xmlParseAttValueComplex() used to call
xmlStringDecodeEntities() in a recursive context without incrementing the
'depth' counter in the parser context. Because of that omission, the parser
failed to detect attribute recursions in certain documents before running out
of stack space.
Integer overflow parsing port number in URI
For https://bugzilla.gnome.org/show_bug.cgi?id=765566
in xmlParse3986Port(), uri->port can overflow when parsing a the port number.
The type of uri->port is int, so the consequent behavior is undefined and
may differ between compilers and architectures
Fix apibuild for a recently added construct
commit c71f9305a99b6aa03cb08fab31106c9c56f1be4f added __XML_EXTERNC
cpp construct which not understood by apibuild, leading to make dist
failures, ask to ignore that construct.

Fix an error with regexp on nullable counted char transition

Fix namespace axis traversal
When the namespace axis is traversed in "toBool" mode, the traversal
can exit early, before visiting all nodes. In this case, the XPath
context still contains a non-NULL tmpNsList.
This means that
- the check when to start a new traversal was wrong and
- the tmpNsList could be leaked.
