xpath: Fix parsing of non-ASCII names
Fix a long-standing issue where QNames starting with a non-ASCII
character would be rejected. This became more visible after "streaming"
XPath evaluation was disabled since the latter handled non-ASCII names
correctly.

xpointer: Remove support for XPointer locations
The latest spec for what it essentially an XPath extension seems to be
this working draft from 2002:
https://www.w3.org/TR/xptr-xpointer/
The xpointer() scheme is listed as "being reviewed" in the XPointer
registry since at least 2006. libxml2 seems to be the only modern
software that tries to implement this spec, but the code has many bugs
and quality issues.
If you configure --with-legacy, old symbols are retained for ABI
compatibility.

parser: Always decode entities in namespace URIs
Also decode entities in namespace URIs if entity substitution wasn't
requested. This should fix some corner cases when comparing namespace
URIs. The Namespaces in XML 1.0 spec says:
> In a namespace declaration, the URI reference is the normalized value
> of the attribute, so replacement of XML character and entity
> references has already been done before any comparison.
Make the serialization code escape special characters in namespace URIs
like in attribute values. This fixes serialization if entities were
substituted when parsing.

expanding entities.
Normalize attribute values in a single pass while expanding entities.

If no entity substitution was requested, validate entities without
expanding. Fixes #596.

Partial revert of cb927e85 fixing CRLFs not incrementing the line

This requires to rework xmlParseQNameHashed. The original implementation
prompted the change to xmlCurrentChar which really shouldn't modify the
'cur' pointer as side effect. But the NEXTL macro relies on this
behavior.
Ultimately, we should reintroduce the change to xmlCurrentChar and fix
the NEXTL macro. This will lead to single CRs incrementing the line
number as well which seems more consistent.

Check for invalid redeclarations of predefined entities
Implement section "4.6 Predefined Entities" of the XML 1.0 spec and
check whether redeclarations of predefined entities match the original
definitions.
Note that some test cases declared
<!ENTITY lt "<">
But the XML spec clearly states that this is illegal:
> If the entities lt or amp are declared, they MUST be declared as
> internal entities whose replacement text is a character reference to
> the respective character (less-than sign or ampersand) being escaped;
> the double escaping is REQUIRED for these entities so that references
> to them produce a well-formed result.
Also fixes #217 but the connection is only tangential. The integer
overflow discovered by fuzzing was more related to the fact that various
parts of the parser disagreed on whether to prefer predefined entities
over their redeclarations. The whole situation is a mess and even
depends on legacy parser options. But now that redeclarations are
validated, it shouldn't make a difference.
As noted in the added comment, this is also one of the cases where
overly defensive checks can hide interesting logic bugs from fuzzers.

add test coverage for incorrectly-closed comments
this establishes the baseline behavior so that subsequent commits
which modify this behavior are clear about what's being changed.

Fix regression introduced with commit 74dcc10b
The code wasn't dead after all, but I can see no reason in delaying
the XPointer evaluation. This could lead to nodes included earlier
appearing in XPointer results.

Fix exponential runtime and memory in xi:fallback processing
When creating XML_XINCLUDE_START nodes, the children of the original
xi:include node must be freed, otherwise fallback content is copied
twice, doubling runtime and memory consumption for each nested
xi:fallback/xi:include pair.
Found with libFuzzer.

Add regexp regression tests
- Bug 757711: heap-buffer-overflow in xmlFAParsePosCharGroup
<https://bugzilla.gnome.org/show_bug.cgi?id=757711>
- Bug 783015 - Integer-overflow in xmlFAParseQuantExact
<https://bugzilla.gnome.org/show_bug.cgi?id=783015>
(Regexptests): Add support for checking stderr output when
running regexp tests. This makes it possible to check in test
cases that fail and not see false-positive error output when
running the tests. Unlike other libxml2 test suites, if there
is no stderr output, no *.err file needs to be created.

Fix quadratic runtime in HTML parser
Commit eeb99329 removed an important optimization avoiding quadratic
runtime when repeatedly scanning the input buffer for terminating
characters in the HTML push parser. The related bug is
https://bugzilla.gnome.org/show_bug.cgi?id=444994
Make sure that ctxt->checkIndex is always written and store additional
parser state in ctxt->inSubset which is unused in the HTML parser.

Fix unability to validate ambiguously constructed interleave for RelaxNG
Previously, test/relaxng/ambig_name-class.xml would fail to validate
for a simple reason -- interleave within "open-name-class" context
is supposed to be fine with whatever else is pending the consumption,
since effectively, it's unrelated from a higher parsing perspective.

Improve XPath predicate and filter evaluation
Consolidate code paths evaluating XPath predicates and filters.
Don't push context node on stack when evaluating predicates. I have no
idea why this was done. It seems completely useless and trying to pop
the context node from a corrupted stack has already caused security
issues.
Filter nodesets in-place and don't create node sets with NULL gaps which
allows to simplify merging a great deal. Simply move matched nodes
backward and create a compact node set.
Merge xmlXPathCompOpEvalPositionalPredicate into
xmlXPathCompOpEvalPredicate.
