Review locking: block signals instead of ignoring them and restore state

afterwards; avoid race condition with unlink; add LCK_HOLD to process_each_vg.

layer appended).
o Got rid of the unused layer->type field and enum.

o Use new LCK_HOLD flag to indicate whether lock should be held on return
...
from lock_vol() - otherwise it now attempts to acquire the lock and then
immediately releases it.
o Extend the id field in struct logical_volume to hold VG uuid + LV uuid
for format1. This unique lvid can be used directly when calling lock_vol().
o Add the VG uuid to vgcache to make VG uuid lookups possible. (Another
step towards using them instead of VG names internally.)

o Lock mechanism for LV activation

o #defines for common lock flag combinations
o Try out hyphens instead of colons in device-mapper names - does this

o _build_name was allocating 1 byte too few, which meant the

terminating zero was falling off at some later point.

o Removed old files

o rewrote activate.c to use dev-manager, I'm sure these two will merge
at some point.
o Rename is broken ATM
o dev-manager puts the calls through to fs.c for layers that have the
