control the number of lines per page rather than a constant. The variable
can be examined and changed in ddb as '$lines'. Setting the variable to
0 will effectively turn off paging.
- Change db_putchar() to force out pending whitespace before outputting
newlines and carriage returns so that one can rub out content on the
current line via '\r \r' type strings.
- Change the simple pager to rub out the --More-- prompt explicitly when
the routine exits.
- Add some aliases to the simple pager to make it more compatible with
more(1): 'e' and 'j' do a single line. 'd' does half a page, and
'f' does a full page.

This is magic and no other operating system do so (i.e. Solaris, Tru64,
Linux, AIX, HP-UX, Irix, MacOS X, NetBSD).

entered the interface start function, no packets were actually dequeued.
Therefore, keep a count of how many packets we really added onto the tx
chain, and initiate a transmit only if the count is non-zero.
for modules linked into the kernel or loaded very early, panics will
result otherwise, as the CV code it calls will panic due to its use
of a mutex before it is initialized.
keyboards to work if no PS/2 keyboard is attached. The position in the
menu was chosen to avoid moving option 6 (loader prompt). This should
be a no-op on non-i386/amd64 machines.
outside of the nice threshold due to a recently awoken thread with a
lower nice value. This further reduces the amount of time a positively
niced thread gets while running in conjunction with a workload that has
many short sleeps (ie buildworld).
under high load: only set function state to loop and continuing sending
if there is no data left to send.

check for TD_ON_RUNQ() no longer means the thread is really on a run-
queue. I suspect this state should be re-evaluated as it must mean
something else now. This fixes ULE+KSE+PREEMPTION on UP x86.
