e3daef5c78 parser: Fix xmlSaturatedAddSizeT argument type 
This is only used for entity size accounting. The bug only affected
platforms where sizeof(long) != sizeof(size_t) and was probably
harmless.

gracefully. Probably regressed with 37c6618b (version 2.13.0).

7c91385040 parser: Remove unnecessary dict checks when freeing strings 
The following strings are never allocated from a dict:

- xmlParserCtxt.version
- xmlParserCtxt.encoding
- xmlParserCtxt.extSubURI
- xmlParserCtxt.extSubSystem
- xmlDoc.version
- xmlDoc.encoding
- xmlDoc.URL
- xmlDTD.ExternalID
- xmlDTD.SystemID
- xmlID.value

Also make the struct members point to non-const chars to avoid casts
when freeing.

e7802738c6 parser: Don't load external content if only XML_SKIP_IDS is set 
At some point, the `loadsubset` member was augmented to also control
handling of ID attributes in addition to loading of external DTDs. These
two features are unrelated and shouldn't have been mixed. This mistake
was probably inspired by the misnamed XML_DETECT_IDS flag. As a side
effect, setting XML_SKIP_IDS always enabled loading of external DTDs and
parameter entities.

This change makes it possible to ignore IDs without loading external
content. This is a deliberate API change that improves security and is
unlikely to affect users.

This also makes sure that the new XML_PARSE_SKIP_IDS option doesn't
enable unsafe behavior.

2f3655c9c3 parser: Pop PEs that start markup declarations explicitly 
We currently only handle "Validity constraint: Proper Declaration/PE
Nesting", but we must detect "Well-formedness constraint: PE Between
Declarations" separately:

> The replacement text of a parameter entity reference in a DeclSep must
> match the production extSubsetDecl.

PEs in DeclSeps are PEs that start with a full markup declaration (or
another PE). These are handled in xmParse{Internal|External}Subset. We
set a flag on these PEs and don't close them implicitly in
xmlSkipBlankCharsPE. This will make unterminated declarations in such
PEs cause a parser error. The PEs are closed explicitly in
xmParse{Internal|External}Subset, the only location where they are
allowed to end.
