SDD 7d299451da reference: TMS34010 SDK investigation; prove GSPA round trip ...

The 1987 DOS toolchain (GSPA/GSPLNK/GSPROM) runs under DOSBox and
reassembles 32 KB of the v2.2 ROM byte-for-byte after five documented
fixups to smart34010 output.  The 1990 r5.01 tools are OS/2 NE and do
not run in DOS.  Adds the converter, round-trip script, and the
DOSBox/dosemu benchmark.
