[svn-r10231] Purpose:

    Bug fix

Description:
    Opening an object in a group that is located in a file which has been
unmounted would cause a core dump. :-(

Solution:
    Re-arrangement internal code to compute internal "user" and "canonical"
names for the newly opened object in a safer way.

Platforms tested:
    FreeBSD 4.11 (sleipnir)
    Too minor to require h5committest
