bdev: Fix position of DEV_MAP

This rather important dictionary from constants to classes was hiding
between function definitions. The dict cannot go to the top of the file
as the classes haven't been defined there yet, so it's been pushed
to the bottom of the file....

Replace physical_id with dynamic_params

The disk field 'physical_id' has to be kept up to date whenever a disk
object is sent to a node via RPC. This is done with the SetDiskID method
manually, which is a source of bugs.

This patch replaces the use of 'physical_id' with a new field names...

Fixing renaming of DISK_LD_DEFAULTS

This fixes the somewhat over-eager renaming of
DISK_LD_DEFAULTS to DISK_DT_DEFAULTS, which clashes
with another occurence of DISK_DT_DEFAULTS. This
patch just undoes the renaming and additionally fixes
a test regarding shared file storage....

Replace LD_* constants with DT_* constants

LD_* constants are basically like DT_* constants, except
for that both file and shared file were mapped to file.
In order to not having to maintain three slightly different
sets of disk-related constants (DT, LD and ST), we merge...

Limit the PVs used for disk growth with exclusive storage

The exclusive storage flag is passed along in the backend functions for
disk growth. LVM volumes handles the flag by reusing the same PVs, as disks
are constrained by the number of their spindles....

Attaching a logical volume builds a list of PVs

When an LV gets attached, the list of the PVs used by the LV is built. This
will be used to count spindles for exclusive_storage, but it could also be
useful to optimize disk growing and snapshotting.

place code there that is related to file storage and leaving
