Changes:
- fdisk_label is a private label driver struct
- generic header of the fdisk_label points to fdisk_label_operations
- the private fdisk_label stuff is always allocated for all drivers
during fdisk_context initialization
- context->labels[] contains pointers to all supported labels (drivers)
- context->label is a pointer to the currently used label
This change allows to:
- store label specific global settings (e.g. dos compatible mode,
display units, ...) independently on the current label
- add label specific function to the API

Get rid of it as a global variable as it belongs in the context.
To compare a disklabel on the device, the fdisk_dev_is_disklabel()
function is introduced. Also, to avoid naming issues, the fdisk_labeltype
members where renamed to FDISK_DISKLABEL_<type>.

The generic fdisk_delete_partition() function returns 0 when a partition
is correctly deleted, otherwise it's corresponding error (negative values).
This, however, does not include problems that can occur in actual label
specific contexts, so we need to propagate the corresponding return code,
back to the user visible api.

- add flags to fdisk_parttype to store more information about the types
- function for conversion from code to fdisk_parttype
- function for conversion from string to fdisk_parttype
- function for conversion from user input to fdisk_parttype
- support for unknown complex types (e.g. unknown UUIDs)

- move MBR partition types to dos_part_types.h
- make dos_part_types.h independent on datetypes to keep it useful in
all fdisks
- add struct fdisk_parrtype
- move label specific partition types to context->label

Rename check_$foo_label() to $foo_probe_label():
1/ 'probe' is more appropriate verb than 'check' for these functions
2/ making label name first part of the funciton name is IMO more
friendly for tags completion (e.g. vim + cscope/ctags).

update_units() is called in _probe_labels before the label probes are
started, so we don't need to call it again in probers, unless it messes
around with geometry, which currently only check_sun_label() does (so
keep the call to update_units() in this one).

This patch sets the initial layout for label specific operations. A
new fdisk_label structure is created that will hold all these ops,
like new, delete, write and probe, among others. For now only probing
is implemented. Once this design is established, a copy of the probed
label will be copied to the main context structure, where calling the
specific functions will save 'disklabel' checks. Debugging support is
added as well.
This patch passes regression tests and manually passes bsd, sun, dos
and sgi labels probes.
