Subject: [svn-r6179] ./hdf5-devel/tools/h5ls/h5ls.c Purpose:     New Feature;
 Optimization; Clean-up     (Merged from 1.4 branch)

Description:
    There is no symbolic constant to pass to functions that take an
    optional object ID for when the caller wants to indicate no object
    ID. In the past the caller always passed a negative integer.

    GPFS performs poorly.

    The h5ls tool decides whether to list the file name in the output
    based on a compile-time choice, which isn't always optimal at run
    time.

Solution:
    Added a symbolic constant H5I_INVALID_HID.

    Added code to tell the mmfsd of GPFS to forego byte range token
    prefetching.

    h5ls decides whether to print the file name at runtime based on
    the number of objects being listed.

Platforms tested:
    SuSE Linux (arborea), gcc and mpich-1.2.4
    SunOS (baldric), gcc

	* main: Replaced the H5LS_PREPEND_FILENAME compile-time symbol which was
	   always defined, with a runtime decision. If h5ls is
	   invoked with more than one argument then the file name
	   is displayed as part of the object name, otherwise the
	   file name is not displayed.
