Implement request #71571: XSLT processor should provide option to change maxDepth (#13731)

Browse source 
There are two depth limiting parameters for XSLT templates.
1) maxTemplateDepth
   This corresponds to the recursion depth of a template. For very
   complicated templates this can be hit.
2) maxTemplateVars
   This is the total number of live variables. When using recursive
   templates with lots of parameters you can hit this limit.

This patch introduces two new properties to XSLTProcessor that
corresponds to the above variables.
