[CVE-2022-40303] Fix integer overflows with XML_PARSE_HUGE
Also impose size limits when XML_PARSE_HUGE is set. Limit size of names
to XML_MAX_TEXT_LENGTH (10 million bytes) and other content to
XML_MAX_HUGE_LENGTH (1 billion bytes).
Move some the length checks to the end of the respective loop to make
them strict.
xmlParseEntityValue didn't have a length limitation at all. But without
XML_PARSE_HUGE, this should eventually trigger an error in xmlGROW.
Thanks to Maddie Stone working with Google Project Zero for the report!

[CVE-2022-23308] Use-after-free of ID and IDREF attributes
If a document is parsed with XML_PARSE_DTDVALID and without
XML_PARSE_NOENT, the value of ID attributes has to be normalized after
potentially expanding entities in xmlRemoveID. Otherwise, later calls
to xmlGetID can return a pointer to previously freed memory.
ID attributes which are empty or contain only whitespace after
entity expansion are affected in a similar way. This is fixed by
not storing such attributes in the ID table.
The test to detect streaming mode when validating against a DTD was
broken. In connection with the defects above, this could result in a
use-after-free when using the xmlReader interface with validation.
Fix detection of streaming mode to avoid similar issues. (This changes
the expected result of a test case. But as far as I can tell, using the
XML reader with XIncludes referencing the root document never worked
properly, anyway.)
All of these issues can result in denial of service. Using xmlReader
with validation could result in disclosure of memory via the error
channel, typically stderr. The security impact of xmlGetID returning
a pointer to freed memory depends on the application. The typical use
case of calling xmlGetID on an unmodified document is not affected.
