[svn-r18710] Purpose:

    Improve configure's large-file support control.

Description:

    Modified configure to now attempt to add defines necessary for
    supporting largefiles on all systems, instead of solely on linux. This 
    is in response to user requests to enable largefile support on Solaris 
    by default, as well as to give extra control on AIX (instead of just 
    jamming the necessary flag into the config files).

    The old --enable-linux-lfs flag is being deprecated in favor of the
    --enable-largefile flag (enabled by default), which can be used on all
    platforms. --disable-linux-lfs can still be used to disable largefile
    support (on linux) when the --enable-largefile flag is not specified.

    On systems where large files cannot be supported in this manner,
    configure will report as such.

Tested:

    h5committest
    AIX (NCSA's blue_print machine)
    duty, liberty, and linew.
