3 temperature sensors supported in the TMS logical device.

With a round of applause to Antti Kantee for helping out with puffs
debugging, and a huge thank you to Greg Oster, who has fixed numerous
bugs over the last week (unfortunately, the bugs are all mine), and
provided enthusiasm and drive.
Right now, the initiator is fulling working for only a single target,
and should be considered to be in a state of flux. Having said that,
Greg completed a run of build.sh with the storage on the iSCSI target,
and found times to be within 0.5% of direct attached storage. Cache
effects apply.
The initiator should be portable to everything that uses the FUSE
interface. That's right - a portable iSCSI initiator.
Storage (LUNs exported by the target) is, at the present time,
presented as a regular file called "storage". This will likely
change in the future.

FFS needs a block device, and so vnconfig can be used to sit on top of
the regular file.

cause nice surprises for e.g. threaded programs. As discussed with

- Introduce sme_class into the sysmon_envsys struct to specify a
class; currently there are two classes: SME_CLASS_ACADAPTER and
SME_CLASS_BATTERY.
- Add a new envsys event: PENVSYS_EVENT_LOW_POWER that is reached when
all SME_CLASS_BATTERY devices are in CRITICAL/LOW state and there's not
any SME_CLASS_ACADAPTER connected.
- Add the 'low-power' event into the sensor_battery script that will
shutdown the system gracefully via 'shutdown -p'. If powerd(8) is
not running, cpu_reboot(9) with RB_POWERDOWN is used.
- Make acpiacad(4) a SME_CLASS_ACADAPTER device and acpibat(4) a
SME_CLASS_BATTERY device.
Update the documentation accordingly to these changes.
- Instead of hooking the handler on the specdev of a mounted file system
hook directly on the `struct mount'.
- Rename from `vn_cow_*' to `fscow_*' and move to `kern/vfs_trans.c'. Use
`mount_*specific' instead of clobbering `struct mount' or `struct specinfo'.
- Replace the hand-made reader/writer lock with a krwlock.
- Keep `vn_cow_*' functions and mark as obsolete.
- Welcome to NetBSD 4.99.32 - `struct specinfo' changed size.
