The apply_dot-config script was wrong: it wouldn't force on the
empty root password. Thus, if it is set to something non-empty
and then changed (by a network dot-config) to empty, it won't work.

This bug only revealed on nfs-root setups.

Now, it's stupid to keep two symbols (ROOT_PWD_CLEAR and ROOT_PWD_CYPHER),
and I could simplify the script. And re-test. And change docs. No thanks.

lm32-vuart was destroying the tty it was run into. And ctrl-C was
not working (the initial message "press ctrl-A" was not really
visible).

This removes part of the cruft of the program. It also adds a little
delay when no bytes are there to read from FPGA to releaf a little
the load on the ARM CPU.

I already fixed that, but likely I made an error in "git rebase -i" before
pushing to master.
