Bring Coverity changes from branch to trunk:
r19161:
Fixed the part for matching the subset info with dataset
r19189:
BZ1646: h5dump does not check number of dimensions for subsetting parameters against the dataset
Changed subset_t structure from holding hsize_t pointers to holding new subset_d pointers, which hold the original hsize_t pointer + len. this len is then checked against dataset ndims in the handle_dataset function of h5dump.
Changed all references to use new data structure.
Added tests for each subset parameter.
r19190:
Added new h5dump ddl files
Tested on:
Mac OS X/32 10.6.4 (amazon) w/debug & production
