64072e0e20 Fix udev support for old libdevmapper with not compatible definition. 
Some released devmapper libraries have defined dm_task_set_cookie()
with not compatible parameters (ABI break), let's check for udev support
by using flags definition (udev is for cryptsetup not usable without this anyway).

4a42f27d78 Detect and use devmapper udev support if available (disable by --disable-udev). 
If we have device-mapper, get ingo using dm_udev_get_sync_support(),
otherwise ignore udev completely.

You can disable udev support by adding --disable-udev to configure, default is enabled.
(There can be races if udev rules run some actions and cryptsetup doesn't wait it.)

c3064c9442 Add temporary debug code to allow better debugging of races 
with various udev-event tools which wrongly scan and open
internal temporary cryptsetup devices.

If cryptsetup run in debug mode (--debug) and remove of device
fails, code scan /proc directory and tries to find process name
which locked that device.

a47856ac49 Use dm-uuid for all crypt devices, contains device type and name now. 
DM_UUID now contains prefix (CRYPT-), device type (LUKS1, PLAIN, TEMP),
UUID (if provided - LUKS) and device name.

Because e.g. snapshot of full LUKS device during activation must have different
name, DM-UUID is different too and we do not need --disable-uuid option.

DM-UUID is persistent during activation time.

* Revert (and solve different way): Replace not safe option --non-exclusive with --disable-uuid.

dca5a38513 Set UUID in device-mapper for LUKS devices. 
Device mapper device should use UUID string if possible.
UDEV can then easily distinguish the device type etc.

cryptsetup now uses CRYPT prefix for uuid.

db96ccef46 Check device size when loading LUKS header. 
(And remove misleading error message later.)

Because kernel and libdevmapper does not provide
better error message then "invalid parameters"
add some error hint if dm-crypt mapping failed.
(Key size and kernel version check for XTS and LRW mode
for now.)
