Subject: [PATCH] CVE-2015-1819 Enforce the reader to run in constant memory
One of the operation on the reader could resolve entities
leading to the classic expansion issue. Make sure the
buffer used for xmlreader operation is bounded.
Introduce a new allocation type for the buffers for this effect.

Subject: [PATCH] Stop parsing on entities boundaries errors
For https://bugzilla.gnome.org/show_bug.cgi?id=744980
There are times, like on unterminated entities that it's preferable to
stop parsing, even if that means less error reporting. Entities are
feeding the parser on further processing, and if they are ill defined
then it's possible to get the parser to bug. Also do the same on
Conditional Sections if the input is broken, as the structure of
the document can't be guessed.

Subject: [PATCH] Cleanup conditional section error handling
For https://bugzilla.gnome.org/show_bug.cgi?id=744980
The error handling of Conditional Section also need to be
straightened as the structure of the document can't be
guessed on a failure there and it's better to stop parsing
as further errors are likely to be irrelevant.

Subject: [PATCH] Fix parsing short unclosed comment uninitialized access
For https://bugzilla.gnome.org/show_bug.cgi?id=746048
The HTML parser was too optimistic when processing comments and
didn't check for the end of the stream on the first 2 characters

Subject: [PATCH] Fail parsing early on if encoding conversion failed
For https://bugzilla.gnome.org/show_bug.cgi?id=751631
If we fail conversing the current input stream while
processing the encoding declaration of the XMLDecl
then it's safer to just abort there and not try to
report further errors.

For https://bugzilla.gnome.org/show_bug.cgi?id=754946
When hitting the end of the current input buffer while parsing
a name we could end up loosing the beginning of the name, which
led to various issues.
