MFC r291126:
Add API to obtain primary enclosure name and ID for /dev/sesX devices.

sesX device number may change between reboots, so to properly identify
the instance we need more data. Name and ID reported here may mach ones
reported by SCSI device, but that is not really required by specs.

Decode common state bits in getencstat output.

Add -c option to sesd to make it clear enclosure status after reading it
in case if it is not permanent and was fixed.

Rise priority of the informational messages from LOG_INFO to LOG_NOTICE,
same as used for OK status. Otherwise it looks strange when OK status is
reported, while informational is not.

Fix a minor typo.

MFprojects/zfsd:

Approved: jkh

Add a minimal example set of how to use the SES ioctls to monitor
SES/SAF-TE devices. It's usable enough (in chpmon) to be alerted as you'd
like to be if a powersupply goes south.
