Literally follow POSIX:
If the bs= expr operand is specified and no conversions other than sync,
noerror, or notrunc are requested, the data returned from each input
block shall be written as a separate output block.

In particular, when both bs=size and conv=sparce were specified, the
resulted file was fully filled, instead of sparce.

IFP4 change 222074.

Introduce an explicit close of the output descriptor so that work done
on close is accounted for in the summary output triggered at exit
(implicit close()s occur after atexit() hooks).

This is useful because some devices such as cfi(4) may perform
signficant work after a close occurs (e.g. erasing and rewriting a
block of flash).

More -Wmissing-variable-declarations fixes.

In addition to adding missing `static' keywords:
- bin/dd: Pull in `extern.h' to guarantee consistency with source file.
- libexec/rpc.rusersd: Move shared globals into an extern.h.
- libexec/talkd: Move `debug' and `hostname' into extern.h.
- usr.bin/cksum: Put counters in extern.h, as they are used by ckdist/mtree.
- usr.bin/m4: Move `end_result' into extern.h.
- usr.sbin/services_mkdb: Move shared globals into an extern.h.

Rework all non-contributed files that use `struct timezone'.

This structure is not part of POSIX. According to POSIX, gettimeofday()
has the following prototype:

int gettimeofday(struct timeval *restrict tp, void *restrict tzp);

Also, POSIX states that gettimeofday() shall return 0 (as long as tzp is
not used). Remove dead error handling code. Also use NULL for a
nul-pointer instead of integer 0.

While there, change all pieces of code that only use tv_sec to use
time(3), as this provides less overhead.

Bump .Dd for r187609

Previous commit broke dd(1)'s I/O summary when it's terminated by a

it handles SIGINFO almost exclusively--so this should be safe.

Do proper constification in args.c. This shuts up -Wcast-qual (thanks,

While I'm here, might as well mark in the Makefile that I'm the

Nuke the FIODTYPE compatibility bits. It's time.

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.

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.

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

ISDISK -> ISSEEK

Allow a device type of D_DISK or D_MEM to be ISSEEK.

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.

Relax things a bit. Not having FIODTYPE will be a warning for now.
