bde 31218d9591 Don't wait for output to drain in pppclose(). Discard output immediately
for the same reasons as in slclose().

Free the cblock in the canonical queue in pppclose().  This is a no-op in
the usual cases where the tty is being closed or the line discipline is
being switched back to the standard discipline, but it saves a cblock if
the line discipline is being switched to one that doesn't use the canonical
queue.

Add prototypes.  I use `extern' in prototypes for functions with bogus
linkage.  This should be fixed someday.

Continue cleaning up new init stuff yet again.
