- Exit if getch() returns with an error other than EINTR. Otherwise
systat(1) may get stuck in an infinite loop if it doesn't receive
SIGHUP when terminal closes. [1]
- Remove attempt to clear stdio error indicators. getch() doesn't use
stdio, making it useless. [2]
- Remove unneeded masking of getch() return value. [2]

certain flags that should have been in inp_flags ended up in inp_vflag,
meaning that they were inconsistently locked, and in one case,
interpreted. Move the following flags from inp_vflag to gaps in the
inp_flags space (and clean up the inp_flags constants to make gaps
more obvious to future takers):
INP_TIMEWAIT
INP_SOCKREF
INP_ONESBCAST
INP_DROPPED
Some aspects of this change have no effect on kernel ABI at all, as these
are UDP/TCP/IP-internal uses; however, netstat and sockstat detect
INP_TIMEWAIT when listing TCP sockets, so any MFC will need to take this
into account.

This commit includes the following core components:
* sample configuration file for sensorsd
* rc(8) script and glue code for sensorsd(8)
* sysctl(3) doc fixes for CTL_HW tree
* sysctl(3) documentation for hardware sensors
* sysctl(8) documentation for hardware sensors
* support for the sensor structure for sysctl(8)
* rc.conf(5) documentation for starting sensorsd(8)
* sensor_attach(9) et al documentation
* /sys/kern/kern_sensors.c
o sensor_attach(9) API for drivers to register ksensors
o sensor_task_register(9) API for the update task
o sysctl(3) glue code
o hw.sensors shadow tree for sysctl(8) internal magic
* <sys/sensors.h>
* HW_SENSORS definition for <sys/sysctl.h>
* sensors display for systat(1), including documentation
* sensorsd(8) and all applicable documentation
The userland part of the framework is entirely source-code
compatible with OpenBSD 4.1, 4.2 and -current as of today.
All sensor readings can be viewed with `sysctl hw.sensors`,
monitored in semi-realtime with `systat -sensors` and also
logged with `sensorsd`.

- p_sflag was mostly protected by PROC_LOCK rather than the PROC_SLOCK or
previously the sched_lock. These bugs have existed for some time.
- Allow swapout to try each thread in a process individually and then
swapin the whole process if any of these fail. This allows us to move
most scheduler related swap flags into td_flags.
- Keep ki_sflag for backwards compat but change all in source tools to
use the new and more correct location of P_INMEM.

- Fix the display on SMP by not scaling the sum of %CPU down
to 1. Instead, display raw data as computed by the kernel,
like in top(1).

disk device names such as da0s1b. So we also get rid of the nasty
constant 5 scattered over the code.
Implementing this change is a good chance to improve other bits
around it: init saved lengths early, always check return value from
kvm_getswapinfo().
1) Resize the Used column to avoid screen overflow if BLOCKSIZE is long.
2) Track the current swap configuration so that its changes don't break
the display.

them unsigned I made the possible overflows hard to detect,
and it only saved 1 bit which isn't principal, even less now
that the underlying issue with the total of virtual memory has
been fixed. (For the record, it will overflow with >=2T of
VM total, with 32-bit ints used to keep counters in pages.)
- While here, fix printing of other "struct vmtotal" members
such as t_rq, t_dw, t_pw, and t_sw as they are also signed.

The policy is that the WARNS level should characterize the
quality of a piece of code irrespective of any conditions.
Otherwise the code doesn't deserve the WARNS level assigned.

for catching general regressions in future. Unfortunately,
it still displays some problems at WARNS=6 on architectures
with stricter alignment requirements, e.g., ia64.
we set and use xtp; if idx is 1, we set and use xip; the other cases
are impossible. However, GCC cannot see that xip and xtp are always
initialized before use because they are initialized and used in
different if/else blocks. So setting them to NULL at the very
beginning won't hurt.
