Return immediately from ttwrite() if the ttysleep()s that wait for
...
a clist return with an error. There are some clist starvation/deadlock
bugs elsewhere and killing clist hogs didn't help because the breaks
only exited from the inner loops.

Round down instead of up in 'kerninfo'/ctrl-T stats code. Incorrect output
...
can result otherwise.

tty modes to process a control-T and do the right thing.

Added code to allocate and deallocate a number of cblocks on open/close of
...
a tty.
Note that this might conflict with the collateral use of TS_WOPEN, but
for the moment I can find no problems associated with this. (TS_WOPEN
will likely go away in the future anyway). This should be looked at
again in the future (the potential problem is that the cblock pool
may either run out or accumulate too many cblocks).
