[svn-r14284] Description:

	Add H5Lvisit_by_name() API routine to library.

	Eliminated all (five!) other group traversal routines and changed them
all to use the new API routine.

	Cleaned up output of h5ls & h5stat:
		- Issue error when requesting recursive traversal of a file
			with the "group info" flag, but no group given
		- Print info about root group in all(?) appropriate situations
		- Don't print "verbose" information about root group until the
			root group is in the list of objects to display
	(mostly because h5ls & h5stat had a different twist on traversing the
groups in a file that the other utilities)

Tested on:
        FreeBSD/32 6.2 (duty) in debug mode
        FreeBSD/64 6.2 (liberty) w/C++ & FORTRAN, in debug mode
        Linux/32 2.6 (kagiso) w/PGI compilers, w/C++ & FORTRAN, w/threadsafe,
                                in debug mode
        Linux/64-amd64 2.6 (smirom) w/default API=1.6.x, w/C++ & FORTRAN,
                                in production mode
        Linux/64-ia64 2.6 (cobalt) w/Intel compilers, w/C++ & FORTRAN,
                                in production mode
        Solaris/32 2.10 (linew) w/deprecated symbols disabled, w/C++ & FORTRAN,
                                w/szip filter, in production mode
        Mac OS X/32 10.4.10 (amazon) in debug mode
        Linux/64-ia64 2.4 (tg-login3) w/parallel, w/FORTRAN, in production mode
