fdisk: API: add geometry
Add device geometry to the fdisk API. While it maintains traditional behaviour, the cylinders
are changed to sector_t instead of unsigned int in order to avoid dealing with truncated cylinders.
A new helper is added to compute the amount of cylinders based on the heads and sectors - if a user passed
-H or -S to the program, it must call this function to update the corresponding values.

fdisk: tests: update oddinput test
Adding mbr to the API breaks this test, specifically when reading the first 512 bytes
of the MBR, update the expected output for oddinput.toosmall. Also let the test create
and remove the test file instead of having it in the expected directory.

fdisk: API: add mbr
This patch adds to the fdisk API the relevant logic to buffers that have MBR. This also serves for
future GPT support for the protective MBR. All labels have been updated to have access to the cxt
structure for the corresponding buffer.
An important observation is that SGI no longer uses the standard qsort(3) function to sort partitions,
as it needs access to cxt. To address this, a heap sort implementation from the kernel was added to
the label code and adapted to fdisk.

When locking the file fails with -n or -w option, caller has no way
to distinguish between the exit code 1 of the -c command,
and the exit code 1 of flock(1) caused by the conflicting lock.
Add a new -E <exitcode> (--conflict-exit-code) option to set
the exit code for the case of locking failure to any value.

libblkid: trust in udev symlinks, don't verify
The libblkid always verify that /dev/disk/by-* symlinks match with
on-device LABELs/UUIDs. It means that all requests (e.g. mount -L |
-U) generates extra superblocks scans on the device.
Currently, many users and tools (GNOME, systemd, ...etc) use the
symlink directly and udev maintains the symlinks by inotify (+watch
rule). It seems better for system performance to disable the extra
paranoid mode and trust in udev.
