This adds some internal limitationson XPath expression complexity,
and limits at runtime like depth of the stack and maximum size
for nodeset.
* xpath.c: implement the above as well as the maximum Name lenght
The count was incremented before the allocation
and not fixed in case of failure
* xpath.c: corrects a few instances where the available count of some
structure is updated before we know the allocation actually
succeeds
This was introduced in the prevous fix, while preceding-sibling and
following sibling axis are empty for attributes and namespaces,
preceding and following axis should still work based on the parent
element. However the parent element is not available for a namespace
node, so we keep the axis empty in that case.

relaxng.c runtest.c tree.c valid.c xinclude.c xmlregexp.c xmlsave.c
xmlschemas.c xpath.c xpointer.c: mostly removing unneded affectations,
but this led to a few real bugs and some part not yet understood
(relaxng/interleave)
* HTMLparser.c c14n.c debugXML.c entities.c nanohttp.c parser.c
testC14N.c uri.c xmlcatalog.c xmllint.c xmlregexp.c xpath.c:
fix unused variables, or unneeded increments as well as a couple
of space issues
* runtest.c: check for NULL before calling unlink()
* include/wsockcompat.h win32/Makefile.bcb xpath.c: fixes for
Borland/CodeGear/Embarcadero compilers by Eric Zurcher

* schematron.c xpath.c: applied a couple of patches from Martin
avoiding some leaks, fixinq QName checks in XPath, XPath debugging
and schematron code cleanups.
* python/tests/Makefile.am python/tests/xpathleak.py: add the
specific regression tests, just tweak it to avoid output by default

* nanohttp.c: fixed problem on gzip streams (bug #438045)
* xpath.c: fixed minor spot of redundant code - no logic change.

* xpath.c: enhanced the coding for xmlXPathCastNumberToString
in order to produce the required number of significant digits
(bug #437179)

* xpath.c: fixed xmlXPathCmpNodes for incorrect result on certain
cases when comparing identical nodes (bug 415567) with patch
from Oleg Paraschenko
svn path=/trunk/; revision=3587
* xpath.c: Changed xmlXPathCollectAndTest() to use
xmlXPathNodeSetAddNs() when adding a ns-node in case of
NODE_TEST_TYPE (the ns-node was previously added plainly
to the list). Since for NODE_TEST_ALL and NODE_TEST_NAME
this specialized ns-addition function was already used,
I assume it was missed to be used with NODE_TEST_TYPE.
* xpath.c: Enhanced xmlXPathCompOpEvalToBoolean() to be also
usable outside predicate evaluation; the intention is to
use it via xmlXPathCompiledEvalToBoolean() for XSLT tests,
like in <xsl:if test="/foo">.
* xpath.c: Added xmlXPathCompiledEvalToBoolean() to the API and
adjusted/added xmlXPathRunEval(), xmlXPathRunStreamEval(),
xmlXPathCompOpEvalToBoolean(), xmlXPathNodeCollectAndTest()
to be aware of a boolean result request. The new function
is now used to evaluate predicates.
* xpath.c: Fixed an bug in xmlXPathCompExprAdd(): the newly
introduced field @rewriteType on xmlXPathStepOp was not
initialized to zero here; this could lead to the activation
of the axis rewrite code in xmlXPathNodeCollectAndTest() when
@rewriteType is randomly set to the value 1. A test
(hardcoding the intial value to 1) revealed that the
resulting incorrect behaviour is similar to the behaviour
as described by Arnold Hendriks on the mailing list; so I
hope that will fix the issue.
* xpath.c: Fixed an error in xmlXPathEvalExpr(), which
was introduced with the addition of the d-o-s rewrite
and made xpath.c unable to compile if XPATH_STREAMING
was not defined (reported by Kupriyanov Anatolij -
#345752). Fixed the check for d-o-s rewrite
to work on the correct XPath string, which is ctxt->base
and not comp->expr in this case.
* xpath.c: Fixed self-invented a segfault in xmlXPathCtxtCompile(),
when the expression was not valid and @comp was NULL and I
tried to do the d-o-s rewrite.
* xpath.c: Enabled the compound traversal again; I added a
check to use this only if the have an expression starting
with the document node; so in the case of "//foo", we
already know at compilation-time, that there will be only
1 initial context node. Added the rewrite also to
xmlXPathEvalExpr().
