libfdisk: properly implement read-only mode

Don't use fallback to read-only mode in fdisk_context_assign_device(),
it's application responsibility open the device in the right mode.

The commands fdisk and cfdisk check (and report) read-only mode now.

build-sys: gettexts 0.18 -> 0.18.2 due to MKDIR_P

The autopoint is designed to not use the latest installed bug fix
release, if you specify

AM_GNU_GETTEXT_VERSION([0.18])

in your configure.ac then it really uses 0.18, rather than also
installed 0.18.2 or 0.18.3. It means that bug fix update has no any
effect. Oh...

The AM_PROG_MKDIR_P is deprecated for years, unfortunately still used
in 0.18 gettext m4 stuff. This problem should be fixed in 0.18.2 where
is the correct AC_PROG_MKDIR_P macro.

If you do not have gettext 0.18.2 (or 0.18.3) then update.

blkid: convert superblocks to new calling convention

With the previous patch the scanning functions were
modified to return a differentiated return code.
To correctly abort scanning when an I/O error occurs
we need to differentiate between 'error' (= -1) and
'not found' (= 1) in the probe functions.
This patch updates all superblock scanning functions
to the new calling convention.

blkid: stop scanning on I/O error

Whenever we fail to read from a device it's pointless to
continue with probing; we should be failing immediately.
Otherwise the system will continue logging I/O errors.

This patch updates the probe functions to return the
negative error number on error and BLKID_PROBE_NONE
if not found.
