When a simple command like 'false' is provided, hush should return the
result of that command. However, hush only does this if the
FLAG_EXIT_FROM_LOOP flag is provided. Without this flag, hush will
happily execute the empty string command immediate after 'false' and
then return a success code.
This behaviour does not seem very useful, and requiring the flag also
seems wrong, since it means that hush will execute only the first command
in a sequence.
Add a check for empty string and fall out of the loop in that case. That
at least fixes the simple command case. This is a change in behaviour but
it is unlikely that the old behaviour would be considered correct in any
case.

Add a bootretry_ prefix to these two functions, and remove the need for
the #ifdef around everything (it moves to the Makefile).

This code is only used by one board, so it seems a shame to clutter up
the readline code with it. Move it into its own file.

This makes it clear where the code resides.

Move the CLI prototypes from common.h to cli.h as part of an effort to
reduce the size of common.h.

Hush is a command-line interpreter, so rename it to make that clearer.
