* gprof.h, gprof.c, printfgprof.c: Add support for two

	* gprof.h, gprof.c, printfgprof.c:  Add support for two
	output styles:  The default is similar to the old FSF gprof,
	while -T sets the variable bsd_style_output, which causes
	output matching Berkeley's gprof.  The biggest differences
	are that with the FSF style output, the flat profile comes
	before the call graph; numbers come before explanations;
	and there is less gratuitous white space.
	* gprof.h, gprof.c, printfgprof.c:  New discard_underscores
	variable causes discarding of initial underscores when
	printing symbol names.  It is set unless there is a "main"
	symbol (without an underscore).
	* printfgprof.c:  New function printnameonly(), called
	by printname().  It handles stripping of initial '_',
	as well as C++ name-demangling.
	* gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
	It is just as convenient to edit blurbs.c directly.
	* Makefile.in:  Removed rule for making blurbs.c.
	* blurbs.c:  This is now a true source file (as opposed
	to being generated from gprof.callg and gprof.flat).
	Change style to use one long string literal, instead of
	one literal per output line.  Add FSF-style blurb for call graph.
