7a507517de Previous commit broke dd(1)'s I/O summary when it's terminated by a 
signal.  Fix it by adding an explicit call to summary() in terminate()
(it was previously called implicitly by exit() because summary() was
registered with atexit()).  summary() is supposed to be signal-safe--
it handles SIGINFO almost exclusively--so this should be safe.

1838cf5671 Let count=-something fail, while count=0 may succeed, thus making dd(1) 
useful as a seeking-tool as well as its many other uses.  Previously,
dd(1) would succeed with count=0, but wouldn't get to the point that
blocks were to be read/written. This is a more useful behavior, and
this specific case doesn't seem to be handled by POSIX.

5868747254 Even more cleanups to dd(1). This is probably the culmination of the 
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.

e14f7e789a Make a bit more headway with dd's argument parsing, etc. get_bsz() is
