Subject: [PATCH 3/3] Don't add IDs containing unexpanded entity references
When parsing without entity substitution, IDs or IDREFs containing
unexpanded entity reference like "abc&x;def" could be created. We could
try to expand these entities like in validation mode, but it seems
safer to honor the request not to expand entities. We silently ignore
such IDs for now.

Subject: [PATCH 2/3] Remove unneeded code in xmlreader.c
Now that no references to ID and IDREF attributes are stored in
streaming validation mode, there's no need to try and remove them.
Also remove xmlTextReaderFreeIDTable which was identical to
xmlFreeIDTable.

Subject: [PATCH 1/3] Rework validation context flags
Use a bitmask instead of magic values to
- keep track whether the validation context is part of a parser context
- keep track whether xmlValidateDtdFinal was called
This allows to add addtional flags later.
Note that this deliberately changes the name of a public struct member,
assuming that this was always private data never to be used by client
code.
