CVE-2015-8035 Fix XZ compression support loop

For https://bugzilla.gnome.org/show_bug.cgi?id=757466
DoS when parsing specially crafted XML document if XZ support
is compiled in (which wasn't the case for 2.9.2 and master since
Nov 2013, fixed in next commit !)

Fix a bug loading some compressed files

There is a bug in xzlib.c which causes certain compressed XML files to fail to
load correctly.  The code in xz_decomp which attempts to verify the checksum
and length of the expanded data fails if the checksum or length at the end of
the file crosses a 1024 byte boundary.  It calls gz_next4 to get those two
values.  This function uses the stream state in state->zstrm, but calls
xz_avail which uses the state->strm stream info.  This causes gz_next4 to
signal a premature EOF if the data it is fetching crosses a 1024 byte boundary.

Fix a regression in xmlGetDocCompressMode()

The switch to xzlib had for consequence that the compression
level of the input was not gathered anymore in ctxt->input->buf,
then the parser compression flags was left to -1 and propagated
to the resulting document.
Fix the I/O layer to get compression detection in xzlib,
then carry it in the input buffer and the resulting document

  This should fix

Fix various bugs in new code raised by the API checking

2012-05-15T02:45:05+00:00

* testapi.c: regenerated and covering new APIs
* tree.c: xmlBufferDetach can't work on immutable buffers
* xzlib.c: fix a deallocation error

Fix a memory leak in the xzlib code

The freeing function wasn't called due to a bogus #ifdef surrounding
value. Also switch the code to use the normal libxml2 allocation and
freeing routines.

fixed a 64bit big endian issue

2012-05-07T10:41:42+00:00

For https://bugzilla.gnome.org/show_bug.cgi?id=671176
patch fixes a 64bit endian issue, making libxml2 work (again) on ppc64
unsigned int and size_t are differently sized on 64bit.

Do not use unsigned but unsigned int

2012-04-02T09:52:20+00:00

as this breaks the API generator

Cleanups of lzma support

2012-01-27T14:19:53+00:00

- fix inclusion of the separated file
- use namespaced name for the 4 non-static routines
- add padding after external structures included in-situ
- add new requirement to spec file
- general cleanup of code

move xz/lzma helpers to separate included files
