ac63841b82 Implement seekability for disk devices (not just regular files).
Also, fix pos_out() to do the same checks pos_in() did.

Done for:	jdp, luigi, the good of the world

788bc0cf60 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.

90290405cf 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.

321c551969 First set of fixes to keep egcs happy. These include {} around single
statement if blocks[*] when the else could be ambiguous, not defaulting
to int type and removal of some unused variables.

[*] This is explicitly allowed by style(9) when the single statement
spans more than one line.

b54fa2acf7 Exit with a nonzero status if we get killed by a SIGINT. POSIX.2
specifies exiting with a zero status if the file was copied
successfully, and with a nonzero status if an error occurred.  We
are too sloppy to tell if the file was copied successfully when we
get killed by a SIGINT, but it is unlikely to have been.  Added a
comment about related sloppiness (calling exit() from a signal
handler).

f4281a32a5 Use the correct value in the call to swab(3) with conv=swab. Previously,
dd if=/dev/zero of=/dev=null obs=23520 conv=swab
coredumped.

Please somebody review it, i'm not 105 % sure i'm understanding all
this mess correctly.

9f4a5b3950 Sort "sparse" into alphabetical order, since dd's `conv' options need
to be sorted.  This temporarily broke the "osync" option.

276d42acd0 Pad the input buffer whenever sync is used, not just if the noerror flag
is also set.
Change osync to not to tack on an empty block if the input buffer is null,
    or an even multiple of the blocksize.
Also change osync to pad the output with nulls/spaces depending whether
   this is a block-oriented conversion or not (same as sync).

68962748a6 Fixed overflow for attempts to seek to offsets > ULONG_MAX. See the
OpenBSD version for more complete fixes.  E.g., to seek to offsets >
INT_MAX using a block size of 1, block numbers need to be off_t's
instead of u_long's.

808a36ef65 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.

6c0fd53b32 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.
