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.
