parser: Fix old SAX1 parser with custom callbacks

Browse Source 
For some reason, xmlCtxtUseOptionsInternal set the start and end element
SAX handlers to the internal DOM builder functions when XML_PARSE_SAX1
was specified. This means that custom SAX handlers could never work with
that flag because these functions would receive the wrong user data
argument and crash immediately.

Fixes #535.
