        src/bin/sh: builtins.def options.c show.c syntax.h

Log Message:
DEBUG mode shell update (changes nothing for shells which are not
compiled for DEBUG.)

Add debug builtin command, and corresponding -D command line option.
As usual, for DEBUG related stuff, read the source for info, that's
all there is about this.

This completes the infrastructure changes for the updated DEBUG TRACE
mechanism, so now converting the rest of the shell's internal tracing
can happen as desired - piecemeal.
