New APIs: cryptsetup-open and cryptsetup-close.

Browse Source 
This commit deprecates luks-open/luks-open-ro/luks-close for the more
generic sounding names cryptsetup-open/cryptsetup-close, which also
correspond directly to the cryptsetup commands.

The optional cryptsetup-open readonly flag is used to replace the
functionality of luks-open-ro.

The optional cryptsetup-open crypttype parameter can be used to select
the type (corresponding to cryptsetup open --type), which allows us to
open BitLocker-encrypted disks with no extra effort.  As a convenience
the crypttype parameter may be omitted, and libguestfs will use a
heuristic (based on vfs-type output) to try to determine the correct
type to use.

The deprecated functions and the new functions are all (re-)written in
OCaml.

There is no new test here, unfortunately.  It would be nice to test
Windows BitLocker support in this new API, however the Linux tools do
not support creating BitLocker disks, and while it is possible to
create one under Windows, the smallest compressed disk I could create
is 37M because of a mixture of the minimum support size for BitLocker
disks and the fact that encrypted parts of NTFS cannot be compressed.

Also synchronise with common module.
