Modify template to include parameters for strtoXXX functions. Also begin
integrating support for 128 bit integer types.

Fix minor bug in int128.h. Also add initial unit tests.

Adding int128.h header with support for GCC specific int128_t and
uint128_t types.

Additional improvements to the fixed point type. Also adding parse_test
which can be used to compare parse performance and a CMakeLists.txt.

Adding initial attempt at creating a custom C++ fixed point template.

Adding local updates to display.py that were never properly committed.

Adding simple email test script to debug email-from-script issues.

Set CXXFLAGS and CFLAGS environment variables for whatever it's worth.

The generate_row.py script is no longer needed but this is officially
the last version of it with all last local modifications.

Adding new script to build ffmpeg and dependencies. Apparently I spent a
good while working on this locally but never committed it.
