[Xsltforms-support] New mechanism for ids generation

[Alain C. <ala...@ag...>]

Hello,

I have modified the way missing ids are generated by the XSLT 
stylesheet: instead of counting preceding nodes (and ancestors), the 
ancestors' position is passed as parameter to templates.

This performance improvement should be useful for big forms and/or slow 
machines. When the form is embedded in a script element, the profiler 
now displays the duration of the XSLT transformation performed with 
Javascript instructions.

Because almost every XSLT templates have be impacted, please consider 
this revision carefully (only in SF SVN repository currently)!

Thank you for your feedbacks!
