We use the code from include/ and lib/ on many places, so use public
domain if possible or LGPL for code copied from libs.

The current loopdev code prefers /sys to get information about
loop devices. The old methods like scan /dev are fallback solution
only. Unfortunately, the code does not check if /sys is mounted.

kernel cryptoloop is deprecated since ages and support for cryptoloop
in util-linux is incomplete/broken.
- no password hashing
- last 8 bit of key are always set to zero
- no binary keys possible (stops reading key at \n and \0)
In the past some Distros added the above features with patches. So
remove cryptoloop support from util-linux completely to make sure
people won't try using it.

Missing semicolon made test_loop_info() to return function
loopcxt_enable_debug() return value, which happen to be void. I
suspect the loopcxt_enable_debug() was usually not executed, while it
should be.

# ll ~/xxx2
-rw-r--r-- 1 root root 500 Jun 12 14:30 /root/xxx2
old version:
# losetup -a
new version:
# losetup -a
/dev/loop0: [2052]:535312 (/root/xxx2)
The new version scans /sys/block/loopN, kernel >= 2.6.37 is required
otherwise fallback to the original not-so-smart /proc/partitions scan.

- improve loop_info usage (don't call ioctl more than once)
- add functions to get devno and inode of the backing file
- add function for compare any file with backing file by devno + inode
or by filename
