HDFFV-5948 - CHICAGO: Tools - implement missing external link test cases
Description:
Merged from HDF5 trunk r20595 and r20600.
Add three test cases for h5dump and h5ls.
- h5ls: external link to soft link with follow symlink.
- h5dump: external link to soft link with follow symlink.
- h5ls: external link to soft link without follow symlink.
Tested:
jam (linux32-LE), amani (linux64-LE), heiwa (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE), cmake
Description: Improved external link traversal of h5dump. h5dump will now
properly avoid all cycles, even those spanning multiple files. Improvement
to the output of committed datatypes. Committed datatypes are now checked
for uniqueness (like other objects). Tests added for these cases.
Tested: kagiso, linew, smirom (h5committest)
