Log message:
*: Move SUBST_STAGE from post-patch to pre-configure
Performing substitutions during post-patch breaks tools such as mkpatches,
making it very difficult to regenerate correct patches after making changes,
and often leading to substituted string replacements being committed.

Add new package Solvespace v2.3
--
SOLVESPACE is a parametric 3d CAD program. Applications include:
modeling 3d parts - draw with extrudes, revolves, and Boolean
(union / difference) operations
modeling 2d parts - draw the part as a single section, and export
DXF, PDF, SVG; use 3d assembly to verify fit
3d-printed parts - export the STL or other triangle mesh expected
by most 3d printers
preparing CAM data - export 2d vector art for a waterjet machine
or laser cutter; or generate STEP or STL, for import into
third-party CAM software for machining
mechanism design - use the constraint solver to simulate planar
or spatial linkages, with pin, ball, or slide joints
plane and solid geometry - replace hand-solved trigonometry and
spreadsheets with a live dimensioned drawing
