Part of fix for Jira issue XALANJ-2375.

Added a new constructor and corresponding reset method that allow the caller
to specify the initial size for the arrays contained in a VariableStack.  This
is important for XPath expression evaluation, where additional stack entries
are never needed.  Previously, the arrays were always allocated based on the
maximum recursion depth permitted by the XSLT processor, which was caused
unnecessary initialization overhead using the various XPath APIs.

Also added two new XPathContext constructors which accept a boolean argument
that indicates whether the context for variables needs to be push/popable.
When it's false, the XPathContext will create a minimally-sized VariableStack.
