b35c55282d Use critical sections as mutex on Windows 
They're more lightweight than ordinary Windows mutexes. Also stop
counting recursive locks. This only hides potential locking bugs.

4adb767763 Simplify recursive pthread mutex

40483d0ce2 Deprecate module init and cleanup functions 
These functions shouldn't be part of the public API. Most init
functions are only thread-safe when called from xmlInitParser. Global
variables should only be cleaned up by calling xmlCleanupParser.

7d02c7291f Fix parser progress checks 
Testing the current input pointer for modification is unreliable since
the input buffer could have been freed and realloced. Check whether the
input id and the up-to-date number of bytes consumed match.

84823b8634 Continue to parse entity refs in recovery mode 
There doesn't seem to be a good reason to abort in xmlParseReference
if a well-formedness error was detected. Removing this check allows to
parse entity references after an error in recovery mode.

Fixes #270.

d99ddd9bd5 Improve buffer allocation scheme 
In most places, we really need the double-it scheme to avoid quadratic
behavior. The hybrid scheme still can cause many reallocations and the
bounded scheme doesn't seem to provide meaningful protection in
xmlreader.c.

4a8c71eb7c Remove DOCBparser 
This code has been broken and deprecated since version 2.6.0, released
in 2003. Because of a bug in commit 961b535c, DOCBparser.c was never
compiled since 2012. I couldn't find a Debian package using any of its
symbols, so it seems safe to remove this module.

1a112c7ba2 Remove regressions.py from Makefile.am 
This patch removes regressions.py and regressions.xml from Makefile.am.
These files were removed in 5ec1ef1c and since they are still in
Makefile.am, it causes "make dist-all" to fail.

ec8ff95ce3 Add support for some non-standard escapes in regular expressions. 
This adds support for some non-standard escape sequences observed
in Microsoft's MSXML DLLs and used by Windows apps, and thus
needed by Wine. Some are also used in other XML implementations,
eg. Java's.

This isn't intended to be final. We probably wish to toggle these
non-standard escape sequences on and off somehow, as needed by
the caller.

2fe372a0aa Properly fold whitespace around the QName value when validating an XSD schema.

966b0f21c1 Add whitespace folding for some atomic data types that it's missing on. 
XSD validation fails when some atomic types contain surrounding whitespace
even though XML Schema Part 2: Datatypes Second Edition, section 4.3.6
says they should be collapsed. Fix this.

(I am not sure whether the test is correct.)

89d9ef3ee8 Reset last error in xmlCleanupGlobals 
Before, we tried to reset the last error in xmlCleanupParser. But if
xmlCleanupParser wasn't called from the main thread, this would reset
the thread-local error object. xmlCleanupGlobals has access to the
error object of the main thread and can reset it reliably.
