e4c2aa64b5 Detect DAX devices and and warn in LUKS format. 
DAX / persistent memory devices do not provide atomic sector updates,
any single modification can corrupt the whole encryption block.

c56bdee177 Add backend support for new device-mapper kernel options. 
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.

683e4db48b Fix warnings reported by static analysis. 
- 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)

54c4b1656f Include sys/sysmacros.h if present.

c57071a43a Fix TCRYPT system encryption mapping for multiple partitions. 
Since this commit, one can use partition directly as device parameter.

Should fix Issue#183 and Issue#188.

3be96efe0b Map TCRYPT system encryption through partition. 
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.

42b0ab437a Print a warning if system encryption is used and device is a partition. 
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.

433758e4cb Fix missing headers 
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.

65f975655c New device access backend. 
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.
