xmlValidatePopElement() can return invalid value (-1)

Browse Source 
Covered by:  test/VC/ElementValid5

This only affects XML Reader API with LIBXML_REGEXP_ENABLED and
LIBXML_VALID_ENABLED turned on.

* result/VC/ElementValid5.rdr:
- Update result to add missing error message.

* python/tests/reader2.py:
* result/VC/ElementValid6.rdr:
* result/VC/ElementValid7.rdr:
* result/valid/781333.xml.err.rdr:
- Update result to fix grammar issue.

* valid.c:
(xmlValidatePopElement):
- Check return value of xmlRegExecPushString() to handle -1, and
  assign 'ret = 0;' to return 0 from xmlValidatePopElement().
  This change affects xmlTextReaderValidatePop() from
  xmlreader.c.
- Fix grammar of error message by changing 'child' to
  'children'.
