This patch adds support for using keyring for volume key
and support for new integrity fields for dm-crypt.
Also helpers for searching disk by id.
To be used later.
- ensure that strings are \0 terminated (most of this is already
handled on higher level anyway)
- fix resource leak in error path in tcrypt.c
- fix time of check/time of use race in sysfs path processing
- insruct Coverity scanner to ignore constant expression in random.c
(it is intented to stop compile-time misconfiguration of RNG that would be fatal)
Kernel doesn't allow mapping through whle device if some
other partition an the device is used.
So first try to find partition device which match
system encryption (== TCRYPT partition system encryption)
and use that.
System encryption hav metadata in space located ouside of
partition itself.
Ideally the check should be automatic but for virtualized systems
(where a partition could be "whole device" for another sustem this
can be dangerous.
2 header inclusions were missing, one for PATH_MAX (limits.h) and one
for FD_ZERO, FD_SET, ... (sys/select.h)
on glibc, those headers are erroneusly (namespace pollution) pulled in
through other headers, so the author didnt notice.

Allocate loop device late (only when real block device needed).
Rework underlying device/file access functions.
Move all device (and ioctl) access to utils_device.c.
Allows using file where appropriate without allocation loop device.
* Add shared flag to libcryptsetup api.
* Fix plain crypt format parameters to include size option (API change).
