[svn-r15368] Description:
Bring back r15367 from the trunk:
Add check to avoid mounting a file on a group twice, when the mounts
are done on the same HDF5 file, but opened with separate H5Fopen queries.
Also add new 'mounted' flag to the H5G_info_t struct, queried with the
H5Gget_info() API call, to allow applications to detect and avoid this
situation.
Tested on:
Mac OS X/32 10.5.4 (amazon)
Linux/64 10.5.4 (chicago)
