+ support for nested procedural variables:
o activate using {$modeswitch nestedprocvars} (compatible with all
regular syntax modes, enabled by default for MacPas mode)
o activating this mode switch changes the way the frame pointer is
passed to nested routines into the same way that Delphi uses (always
passed via the stack, and if necessary removed from the stack by
the caller) -- Todo: possibly also allow using this parameter
passing convention without enabling nested procvars, maybe even
by default in Delphi mode, see mantis #9432
o both global and nested routines can be passed to/assigned to a
nested procvar (and called via them). Note that converting global
*procvars* to nested procvars is intentionally not supported, so
that this functionality can also be implemented via compile-time
generated trampolines if necessary (e.g. for LLVM or CIL backends
as long as they don't support the aforementioned parameter passing
convention)
o a nested procvar can both be declared using a Mac/ISO Pascal style
"inline" type declaration as a parameter type, or as a stand-alone
type (in the latter case, add "is nested" at the end in analogy to
"of object" for method pointers -- note that using variables of
such a type is dangerous, because if you call them once the enclosing
stack frame no longer exists on the stack, the results are
undefined; this is however allowed for Metaware Pascal compatibility)

* For ancestor and ancestor-or-self axes, added checks for attribute nodes similar to parent axis.
* For reverse axes, collect and filter nodes in 'natural' (i.e. reversed) order, and only then reverse order while adding to result node set. This is much simpler to implement.
* Fixed memory leak (not destroying TXPathFilterNode.FExpr)
git-svn-id: trunk@15652 -
o The prefix to resolve should not include following ':*' characters
o NextToken changes CurTokenString, so NextToken must be after reading CurTokenString.
o Added a test for that
* XPath test suite, fixed comparison of numeric result (it is quite tricky in presence of NaNs).

- Deleted TXPathLocationPathNode, it was too much overhead to store a single bit of information. The path root (if any) is now represented by TStep node with Axis=axisRoot.
* Changed TStep linkage from 'right' to 'left', this is consistent with the way of parsing expressions and considerably simplifies evaluation.
* Fixed ParsePathExpr procedure so it no longer accepts empty/truncated expressions.
