[svn-r25197] Description:

    Bring changes from hdf5_1_8_coverity branch back to trunk:

r20878:
    Issue 76: Check if H5Tget_nmembers(type) fails and simply return(FALSE). Also move printf to after check.

r20880:
    Issue 192: Create ret_val var set to -1. Add out label for failures to jump to, return ret_val at bottom.

r20882:
    Fixes for coverity:
    1) bug #1679: remove dead code in test/mf.c
    2) bug #1680: remove dead code in tools/lib/h5diff_dset.c

r20883:
    Fix coverity issue 585

    Description:
    Changed variable "c" in processStrData in h5import.c to an int, to match fgetc
    return value, and removed call to feof, instead checking if c == EOF.

Tested on:
    MacOSX/64 10.9.3 (amazon) w/C++, FORTRAN & parallel
    (too minor to require h5committest)
