Fix a long-standing bug related to rebooting while a
reconstruct-to-spare is underway but not yet complete.
The issue was that a component was being marked as a used_spare when
the rebuild started, not when the rebuild was actually finished.
Marking it as a used_spare meant that the component label on the spare
was being updated such that after a reboot the component would be
considered up-to-date, regardless of whether the rebuild actually
completed!
This fix includes:
 1) Add an additional state "rf_ds_rebuilding_spare" which is used
    to denote that a spare is currently being rebuilt from the live
    components.
 2) Update the comments on the disk states, which were out-of-sync
    with reality.
 3) When rebuilding to a spare component, that spare now enters the
    state rf_ds_rebuilding_spare instead of the state rf_ds_used_spare.
 4) When the rebuild is actually complete then the spare component
    enters the rf_ds_used_spare state.  rf_ds_used_spare is now used
    exclusively for the case where the rebuilding to the spare has
    completed successfully.
XXX: Someday we need to teach raidctl(8) about this new state, and
take out the backwards compatibility code in rf_netbsdkintf.c (see
RAIDFRAME_GET_INFO in raidioctl()).  For today, this fix needs to be
generic enough that it can get backported without major grief.
XXX: Needs pullup to netbsd-5*, netbsd-6*, and netbsd-7

Parse the extension block count field, and make it available in struct edid_info
--
add ddc_read_edid_block, which is the same as ddc_read_edid but takes an additional block number argument
--
Add support for DVI displays. Detect HDMI vs DVI mode by looking for a
CEA-861-D extension block in the EDID, and then searching this block for
an HDMI vendor-specific data block (HDMI VSDB).
--
Allow for overriding DVI/HDMI detection with a kernel boot arg. Set
hdmi.forcemode=dvi or hdmi.forcemode=hdmi to disable auto-detection.

report hotplug status for AUDIO_GETDEV fields, only allow playback if a capable display is connected
--
clear repeater sel bits before setting -- would cause an issue if we ever switched away from a pixel doubling mode

Fix use-after-free on failed unmount with extended attribute enabled
When unmount failed, for instance because the mount is still busy,
UFS1 extended attributes structures were left freed while the kernel
assumes extended attributes were still enabled. This led to using
UFS1 extended attributes structures after free. With LOCKDEBUG, with
quickly triggers a panic.
The problem is fixed by:
1) clear MNT_EXTATTR flag after extended attributes structures are freed
2) attempt to restart extended attributes after failed unmount
2) set MNT_EXTATTR correctly after extended attributes restart
As a side effect, extended attribute structures are now only initialized
when extended attributes are started for the filesystem.

	sys/ufs/ufs/ufs_extattr.c: revision 1.45
Fix UFS1 extended attribute backend autocreation deadlock
UFS1 extended attribute backend autocration goes through a vn_open()
to create the backend file, and this forces us to release the lock
on the target node, in case the target is within the parents of the
backend file. That created a window within which another thread could
acquire a lock on the target vnode and deadlock awaiting for the
mount extended attribute lock.
We fix the problem by also releasing the mount extended attribute lock
when calling vn_open(), but that lets another thread race us for backend
creation. We just detect this using O_EXCL for vn_open() and by checking
for EEXIST return code. If we are raced, we fail backend creation but
this is not a problem since another thread succeeded on it: we just have
to use the result.

Remove unused extended attributes kernel options

As Masao Uebayashi pointed to me, UFS_EXTATTR_AUTOSTART, LFS_EXTATTR_AUTOSTART
and UFS_EXTATTR_AUTOCREATE are not used anywhere in the code. Remove them
as they have been obsolete for a long time:
UFS_EXTATTR_AUTOSTART was replaced by mount -o extattr
LFS_EXTATTR_AUTOSTART was created to match obsolete UFS_EXTATTR_AUTOSTART
UFS_EXTATTR_AUTOCREATE was replaced by sysctl vfs.ffs.extattr_autocreate
