parser: Rework handling of undeclared entities
Throw an error if entity substitution was requested.
Now we only downgrade to a warning if
- XML_PARSE_DTDLOAD wasn't specified, and
- entity aren't substituted or XML_PARSE_NO_XXE was specified.
Should fix #724.

parser: Consolidate error handling for undeclared entities
Always use XML_WAR_UNDECLARED_ENTITY with warning error level in
documents with external subset or parameter entities. Use
XML_ERR_UNDECLARED_ENTITY otherwise.

parser: Fix entity check in attributes
Don't set the "checked" flag when checking entities in default attribute
values. These entities could reference other entities which weren't
defined yet, so the check isn't reliable.
This fixes a short-lived regression which could lead to a call stack
overflow later in xmlStringGetNodeList.
