[svn-r19134] Description:
Bring r19133 from trunk to 1.8 branch:
Correct traversal of user-defined links (including external links) to
retain path information of object, allowing H5Iget_name() queries to work
quickly (without searching entire destination file). This required some
refactoring and addition of a mechanism to detect if a "fast" query was
performed (for the tests).
Minor code cleanups, etc.
Tested on:
FreeBSD/32 6.3 (duty) in debug mode
FreeBSD/64 6.3 (liberty) w/C++ & FORTRAN, in debug mode
(h5committest performed on trunk)
