6784d416a5 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.

c183a03b17 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).

eccad22277 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.

902d9eafbf 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.

4dd47928b7 Add an example of using bs=2048 to duplicate data CD-ROMs.
This should be a bit useful for users who look at the manpage and
then try to copy data CD-ROM disks using dd.  A lot of us know
that bs=2048 is required, but it still manages to cause a bit of
grief to those who haven't heard about it.

e3edab4a91 Add a "fillchar" command line argument to dd(1) that permits the user
to specify an alternative padding character when using a conversion
mode, or when using noerror with sync and an input error occurs.  This
facilities reading old and error-prone media by allowing the user to
more effectively mark error blocks in the output stream.

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.
