* xmlsave.c: applied second patch from David Madore to be less intrusive
when handling scripts and style elements in XHTML1 should fix#316041
* test/xhtml1 result//xhtml1\*: updated the test accordingly
Daniel
* tree.c include/libxml/tree.h: modified the existing APIs
to handle XHTML1 serialization rules automatically, also add
xmlIsXHTML() to libxml2 API. Some tweaking to make sure
libxslt serialization uses it when needed without changing
the library API.
* test/xhtml1 result/noent/xhtml1 result/valid/xhtml1.xhtml
result/xhtml1: added a new test specifically for xhtml1 output
and updated the result of one XHTML1 test
