Remove G_TYPE_ASCLBA type and replace it with G_TYPE_STRING in gpart.
Move code that converts params from humanized numbers to sectors count
to subr.c and adjust comment.
Add post-processing for "size" and "start offset" params in gpart,
now they are properly converted to sectors count with known sector size
that can be greater that 512 bytes.
Also replace "unsigned long long" type to "off_t" for unify code since
it used for medium size in libgeom(3) and DIOCGMEDIASIZE ioctl.
