[svn-r14251] Description:

Browse Source 
Move setting the "update the dataset's dataspace" flag later in the process
of changing it's extent.  Also add explicit check for having write access to
file, before attempting to perform any actions for changing the extent.

Tested on:
    Linux/64 2.4 (smirom) w/parallel
