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: 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.

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.

fdisk: fix io_size usage in new API
properly implemented fdisk_dev_has_topology() requires optimal
I/O size to detect that the device provides topology.
Unfortunately, currently used cxt->io_size maybe overwritten in
__discover_topology() to min_io_size.
This patch introduces cxt->optimal_io_size and keeps it independent on
cxt->io_size. The cxt->io_size is I/O size used by fdisk for alignment
calculation.

fdisk: add device topology to the API
This patch adds device topology discovery to the internal API. This
functionality is static only to the API and therefore hidden from general fdisk
code. Functionality itself doesn't really change, min_io_size, io_size, logical
and physical sector sizes and alignment offset are added to the fdisk_context
structure and elements are accessed from there. The logical sector size
(sector_size) is now unsigned long instead of unsigned int, this as no effect
otherwise.
A few things to notice:
- The patch is larger than I wanted but we need to modify function parameters
across fdisk and its labels to use the topology data from cxt-> instances.
Hopefully this will be pretty much it regarding this kind of modifications -
perhaps geometry will need something of the like too.
- The -b option must override internal discovery.
- A new helper function has added to verify if the device provides topology
information, this replaces the 'has_topology' global variable.

fdisk: use context as a parameter
This program heavily uses global variables, which isn't very elegant and can
lead to nasty bugs. Modify functions that use fdisk's context current features
(descriptor and path), to receive the context as a parameter instead of

comes with this is that as the API grows all the information regarding fdisk
will be accessible from this structure so we can reduce even more global
variables and simply code.
