7503d74f54 WARNS=4 fixes. This would be WARNS=9 if we were -std=99 instead of
-ansi, due to 'long long'.

c15c898eff Various cleanups are made to reduce warnings and make code prettier :)
Also, check for ftruncate() return value and die on failure, but only
try to ftruncate() when the file is a regular file.

7599187e0d Even more dd(1) cleanups! Thanks to Bruce for staying on my case until
we're done (not yet!) :)

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.

769e5815e3 Implement seekability for disk devices (not just regular files).
Also, fix pos_out() to do the same checks pos_in() did.

54946e00b2 This is the second round of dd(1) changes. Some changes made/reversed by
request of Bruce. More changes may follow later. 'g' multiplier has
been added (i.e. dd seek=5g if=bigfile.) Some minor corrections were made
as well.

767bc8ad79 Miscellaneous dd(1) changes: mainly fixing variable types (size_t, ssize_t,
off_t, int, u_int64_t, etc.). dd(1) should now work properly with REALLY
big amounts of data.

4ddfeabd8f Teach dd(1) about an option to write sparse files. Can be useful for
things like diskless clients' swap files etc.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

ad66f7ee71 Bruce says: "You have been programming in the kernel for too long :-)."
and he's right ... I forgot about this floating point stuff you can
use in user-land :-)

Increase precision of duration to microseconds.
No heuristics to avoid overflow in calculation needed - just depend
on DBL_MAX being a bit larger than LONG_MAX.

Use double instead of `struct timeval' in dd.h so that everything
doesn't have to include <sys/time.h>.

Fixed style bugs in recent and old FreeBSD changes.
