6e6ef95ba6 Implement lock-override options without locking type
The options: --nolocking, --readonly, --sysinit
override, or make exceptions to, the normal file locking
behavior.  Implement these by just checking for the
options in the file locking path instead of using
special locking types.

da30b4a786 Remove locking infrastructure from activation paths
Basic LV functions:

  activate_lv(), deactivate_lv(),
  suspend_lv(), resume_lv()

were routed through the locking infrastruture on the way to:

  lv_activate_with_filter(), lv_deactivate(),
  lv_suspend_if_active(), lv_resume_if_active()

This commit removes the locking infrastructure from the
middle and calls the later functions directly from the former.

There were a couple of ancillary steps that the locking
infrastructure added along the way which are still included:

  - critical section inc/dec during suspend/resume
  - checking for active component LVs during activate

The "activation" file lock (serializing activation) has not
been kept because activation commands have been changed to
take the VG file lock exclusively which makes the activation
lock unused and unnecessary.

616eeba6f2 use exclusive file lock on VG for activation
Make activation commands:
  vgchange -ay, lvchange -ay, pvscan -aay

take an exclusive file lock on the VG to serialize
multiple concurrent activation commands which could
otherwise interfere with each other.

e7aa51c70f Remove VG lock ordering check
Four commands lock two VGs at a time:

- vgsplit and vgmerge already have their own logic to
  acquire the locks in the correct order.

- vgimportclone and vgrename disable this ordering check.

18259d5559 Remove unused clvm variations for active LVs
Different flavors of activate_lv() and lv_is_active()
which are meaningful in a clustered VG can be eliminated
and replaced with whatever that flavor already falls back
to in a local VG.

e.g. lv_is_active_exclusive_locally() is distinct from
lv_is_active() in a clustered VG, but in a local VG they
are equivalent.  So, all instances of the variant are
replaced with the basic local equivalent.

For local VGs, the same behavior remains as before.
For shared VGs, lvmlockd was written with the explicit
requirement of local behavior from these functions
(lvmlockd requires locking_type 1), so the behavior
in shared VGs also remains the same.

1539e51721 devices: clean up io error messages
Remove the io error message from bcache.c since it is not
very useful without the device path.

more user friendly.
