getting changed by "make ship" because the build is done in a place
where the path pointer to the user_id_programming GDS still points
back to the original caravel repository, not the user project
repository. The user_id_programming GDS was removed (no longer used),
the user_id_programming.mag file was modified to remove the path
pointer to the GDS, and the set_user_id.py script was modified to
make changes directly to the user_id_programming.mag file instead of
the GDS. An additional method was added to the set_user_id.py script
to modify the gate-level verilog/gl/user_id_programming.v to make
the user ID correct for gate-level testbench simulations.
characters in the user_id_textblock layout, which was backwards,
and (2) add a path reference to "hexdigits" for each new character
layout encountered in the file, so that the text block layouts
are found even if "addpath hexdigits" has not been specified.
There were some other corrections to handling gzipped files that
probably does not apply in practice, where "make uncompress" has
been run prior to the set_user_id.py script.
