Almost any code calling get_terminal_width() checks returned width for
non-positive values and sets it to some default value (say, 80). So,
let's pass this default value directly to the function.
[kzak@redhat.com: - get_terminal_width() refactoring]

* removes list() label operation from internal API
The list() has been based on fdisk_info() it was useless for
anything else than print on stdout...
* add a new get_item() label operation and fdisk_get_disklabel_item() public API
The new API provides abstract and pretty simple way how to get label
specific disk label information, for example
fdisk_get_disklabel_item(cxt, GPT_LABELITEM_ENTRIESLBA, &iterm);
return LBA of the array with GPT entries.
Note that this patch does not implement public functions to get
data from the @item object.
* removes get_id() label operation -- it's subset of the new get_item()
* the new internal API is also used to implement backwardly compatible
fdisk_list_disklabel() and fdisk_get_disklabel_id()

The function uses "int" as argument, but for array size (and index) is better
to use unsigned type (size_t). If we mix "size_t" in util (e.g. fdisk)
and "int" in lib/strutils.c then result is unexpected behavior on
ppc64.

The patch cleanup all code to use size_t everywhere.

The zero may be valid size and start of the partition. This patch
introduces:
fdisk_partition_has_start()
fdisk_partition_has_size()
fdisk_partition_unset_size()
fdisk_partition_unset_start()
to make it possible to work with zero. The feature is internally
implemented by magic constant ((type) -1) for undefined sizes and
offsets.
