Non-controversial whitespace cleanup

Nothing to do with tab width!  Eliminates useless
trailing spaces and tabs, and nearly all <space><tab>
pairings.  No change to derived files (e.g., .vvp),
non-master files (e.g., lxt2_write.c) or the new tgt-vhdl
directory.

Low priority, simple entropy reduction.  Please apply
unless it deletes some steganographic content you want
to keep.
