[libxml2] Bug 760183: REGRESSION (v2.9.3): XML push parser fails with bogus UTF-8 encoding error when multi-by

commit 4f8606c13cb7f2684839f850b83de5ce647d3ca7
Author: David Kilzer <ddkilzer apple com>

    Bug 760183: REGRESSION (v2.9.3): XML push parser fails with bogus UTF-8 encoding error when multi-byte 
character in large CDATA section is split across buffer <https://bugzilla.gnome.org/show_bug.cgi?id=760183>
    
    * parser.c:
    (xmlCheckCdataPush): Add 'complete' argument to describe whether
    the buffer passed in is the whole CDATA buffer, or if there is
    more data to parse.  If there is more data to parse, don't
    return a negative value for an invalid multi-byte UTF-8
    character that is split between buffers.
    (xmlParseTryOrFinish): Pass 'complete' argument to
    xmlCheckCdataPush() as appropriate.

    * result/cdata-2-byte-UTF-8.xml.rde: Added.

      fails prior to the fix.
