Tim Edwards 4a27ea4c6b Finished first draft of the gen_gpio_defaults.py script, which now 
makes backup copies of caravel and caravan layouts and replaces the
cell name of any gpio defaults block that is changed from the
contents of user_defines.v.  NOTE:  user_defines.v ultimately must
reside in the user project.  The Makefile should copy the user's
version into the caravel directory space before running the script,
or else the script should be rewritten to reference the user's
project area when reading user_defines.v.

Tim Edwards 6a93ea582d Added a script which parses the file "user_defines.v" in 
verilog/rtl/, and creates all the layout files needed to represent
all unique combinations of defaults used in the file.  Not done:
Modifying the top level layout to use the correct defaults (because
the top level layout does not yet exist).
