[PATCH 0/8] Implement a new DTS Source Language

[Jon Loeliger <jdl-CYoMK+44s/E@public.gmane.org>]

This series of patches enhances the DTS source language to
support a fullly interpreted language for generating nodes
and properties.  It is backward compatible with V1 sources.

The main features implemented by this patch set support
function definitions, 'if', 'for', 'return' and assignment
statements.  Local variables, global constants and
almost complete C-like expressions are also supported.

Enhancements to the source position and error/warning
reporting now support source column positions too.

Jon Loeliger (8):
  Remove support for the legacy DTS source file format.
  Add conditionalized debug() print macro.
  Enhance source position implementation.
  Add header files for new Internal Representation form.
  Add most of the new IR implementation files.
  Add the main IR evaluation implementation
  Introduce new DTS language.
  Add documentation for the new DTS language.
