| | | | | | | | | | | | | BDEification process of dd(1). Most of the changes are from BDE's archive. Support for negative offsets is gone again, but the case where you lseek() onto byte -1 of something from a negative offset using seek/skip is fixed; if you end up on -1, you won't get a false positive lseek failure. The biggest changes are to data types (more size_t, for instance) and argument parsing. skip/seek on /dev/{,k}mem now occurs (instead of "read until you reach the offset") due to mem devices now being D_DISK. Some const things are now correctly declared as such, and the "case table" building is better. The only thing that seems to be left to make dd(1) everything TOG wants it to be is l10n.

| | | | | renamed get_num() since it's not just about block sizes. skip and seek can be any offset, including negative, now. Some style bogons are fixed.
