Fix use-after-free in xmlParseContentInternal()
* parser.c:
(xmlParseCharData):
- Check if the parser has stopped before advancing
`ctxt->input->cur`. This only occurs if a custom SAX error
handler calls xmlStopParser() on fatal errors.

parser: Fix regression when switching input encodings
Revert some changes from commit 98840d40.
WebKit/Chromium can actually switch from ISO-8859-1 to UTF-16 in the
middle of parsing. This is a bad idea, but we have to keep supporting
this use case.

[CVE-2023-29469] Hashing of empty dict strings isn't deterministic
When hashing empty strings which aren't null-terminated,
xmlDictComputeFastKey could produce inconsistent results. This could
lead to various logic or memory errors, including double frees.
For consistency the seed is also taken into account, but this shouldn't
have an impact on security.

xmlValidatePopElement() can return invalid value (-1)
Covered by: test/VC/ElementValid5
This only affects XML Reader API with LIBXML_REGEXP_ENABLED and
LIBXML_VALID_ENABLED turned on.
* result/VC/ElementValid5.rdr:
- Update result to add missing error message.
* python/tests/reader2.py:
* result/VC/ElementValid6.rdr:
* result/VC/ElementValid7.rdr:
* result/valid/781333.xml.err.rdr:
- Update result to fix grammar issue.
* valid.c:
(xmlValidatePopElement):
- Check return value of xmlRegExecPushString() to handle -1, and
assign 'ret = 0;' to return 0 from xmlValidatePopElement().
This change affects xmlTextReaderValidatePop() from
xmlreader.c.
- Fix grammar of error message by changing 'child' to
'children'.

SAX2: Ignore namespaces in HTML documents
In commit 21ca8829, we started to ignore namespaces in HTML element
names but we still called xmlSplitQName, effectively stripping the
namespace prefix. This would cause elements like <o:p> being parsed
as <p>. Now we leave the name untouched.

parser: Rework EBCDIC code page detection
To detect EBCDIC code pages, we used to switch the encoding twice and
had to be very careful not to decode data after the XML declaration
before the second switch. This relied on a hard-coded expected size of
the XML declaration and was complicated and unreliable.
Now we convert the first 200 bytes to EBCDIC-US and parse the encoding
declaration manually.

malloc-fail: Stop using XPath stack frames
There's too much code which assumes that if ctxt->value is non-null,
a value can be successfully popped off the stack. This assumption can
break with stack frames when malloc fails.
Instead of trying to fix all call sites, remove the stack frame logic.
It only offered very little protection against misbehaving extension
functions. We already check the stack size after a function call which
should be enough.
