    Make ICC profile management thread safe.
    
    The change to ref_count of profiles needs to be protected by a lock if
    the profile ref_count could be changed by another thread. Also when
    decrementing the ref_count to 0, we cannot free the lock until after
    the profile has been unlocked.
    
    New routine gsicc_adjust_profile_rc replaces old (not threadsafe) function
    gsicc_profile_reference.
    
    Also add tracing "cname" to the RC_ADJUST_ macro to aid in debugging
    with -Z^ debug flag.
    
    Testing had revealed race conditions which are now fixed (eliminate use
    of semaphores).
    
    This also changes the gsicc_lcms2art.c interface functions to keep a
    list of transforms configured to have differing buffer formats that
    include alpha, planar IN/OUT, big_endian IN/OUT, bytes_per_component
    IN/OUT which are cloned as needed by threads.
    
    Change gscms_is_threadsafe to return "true" in gsicc_lcms2art.c
    
    TBD: If a link fails to build a thread may hang waiting for the link
    profile to become valid if it was not the thread that was building it.
    Not a new condition, but exposed when gscms_is_threadsafe returns true.
    
    TBD: Fix error handling / clean-up when links fail to build. Also not
    new, but is needed to prevent leaks, and possibly hang conditions.
