r302500 (by cem):
dd(1): Enable access to SIZE_T_MAX character devices
On machines where SIZE_T_MAX exceeds OFF_MAX (signed 64-bit), permit seeking character devices to negative off_t values. This enables dd(1) to interact with kernel KVA in /dev/kmem on amd64, for example.
r319339 (by asomers):
Fix integer overflow detection in dd
dd(1) tried to detect whether the seek offset would overflow, but it failed to account for the case where the provided argument was negative and the file was a regular file (negative seeks are allowed for character devices). I fixed it, and added a regression test.

Stylistic tweaks
Move opening braces of functions from the last column to column 0.

r319551 (by asomers):
Fix bin/dd/dd2_tests:seek_overflow on UFS and TMPFS
Split the postive and negative parts into separate test cases. The positive test case can only run on ZFS, because only ZFS supports files that large.

r321138:
Remove unnecessary make logic added in r319339
This makes the change cleaner and easier to backport to ^/stable/10.

Allow negative seek offsets for files that can be seeked upon. It makes dd(1) a more complete "filter", even if this functionality is limited to seekable streams.

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.

Make count=0 set cpy_cnt to -1, which is slight overloading, but makes what I was trying to do work much better (ie at all. I could have sworn it was working...) Fix a SEEK_SET to be SEEK_CUR, and make Bruce's lseek() test work correctly.

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.

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

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.

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.

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.
