[PATCH] add xslt_stylesheet_param directive

[SamB]

Hi,

   I've added xslt_string_param and slightly changed parameter passing and
transformation
   to make it work as expected.
   As a side effect of this change, might be usage of
xslt_param/xslt_string_param faster,
   because params are directly inserted to transformation context and do
not need to be
   copied to name/value parameter array that is passed to
xsltApplyStylesheet() as it's now
   by parameters passed via xslt_stylesheet directive.

   Old parameter passing using xslt_stylesheet has not been changed to
prevent unexpected behavior,
   maybe this can be modified later if this patch will prove to be stable...
