rework old-style functions prototypes
reduce WARNS=6 output

More fixes for correct printf length modifiers usr.bin/gprof.

MFC after: 1 week

Remove the advertising clause from UCB copyrighted files in usr.bin. This
is in accordance with the information provided at
ftp://ftp.cs.berkeley.edu/pub/4bsd/README.Impt.License.Change

Also add $FreeBSD$ to a few files to keep svn happy.

Discussed with: imp, rwatson

Retire support for gprof's -c option. All our currently supported
architectures only provide a dummy implementation.

Silence on: current@

Remove done() which was just exit() so use of warn()/err() can be made. Abort
on allocation failure instead of displaying a warning and deferencing NULL
pointer after. Spelling. Add prototypes. Add list of option in synopsis section
of man page, -d is not referenced because available as a compile option. It
should be made a runtime option btw.

Consistently use FBSDID

Fix preprocessor directive syntax (text after #endif).
The style of this program is still atrocious (not fixed).

Fixed printf format errors. In printgprof.c, also convert the scale
without possibly losing lots of precision, and print the scale using
%g instead of %d in case it is non-integral. %g might not be the best
format for this.

Fixed a missing variable declaration so that gprof compiles with -DDEBUG.

$Id$ -> $FreeBSD$

Revert to original style.

Fix typo I introduced during last commit.

Use err(3).

Remove trailing whitespace.
