getdate -> parsedate

getdate is in libutil.

Add -d option, similar to gnu date.

Add -j flag to not actually change the clock, just parse the date given
(if any) and then display it in the format given. Matches similar -j
flag functionality in FreeBSD/OpenBSD.

Change requested by George Georgalis on netbsd-users.

While I'm here, disambiguate the letters in the date string, by using
the same option letters as used by strftime(3).

PR/28450: David H. Gutteridge: date(1) does not validate its input and

Patch applied, thanks!

don't include program name when calling err()

PR/34055: Kevin Massey: Date uses a fixed 1K buffer for strftime
but does not check when strftime fails because the buffer is too small.
Our implementation of strftime does not NUL terminat the buffer
on failure (it does not have to; the results are undefined), so
garbage gets printed. Use a dynamically allocated buffer instead.

More minor cleanup:
- remove unnecessary prototype for main()
- use symbolic exit code
- KNF & wrap a long line

* remove unneeded cast
* use err() instead of perror() + exit()
