parser: Report malloc failures

Browse Source 
Fix many places where malloc failures aren't reported.

Make xmlErrMemory public. This is useful for custom external entity
loaders.

Introduce new API function xmlSwitchEncodingName.

Change the way how we store whether the the parser is stopped. This used
to be signaled by setting ctxt->instate to XML_PARSER_EOF which was
misdesigned and error-prone. Set ctxt->disableSAX to 2 instead and
introduce a macro PARSER_STOPPED. Also stop to remove parser inputs in
xmlHaltParser. This allows to remove many checks of ctxt->instate.

Introduce xmlErrParser to handle errors if a parser context is
available.
