[svn-r19801] Purpose:
Add additional error checking to catch erroneous user input.
Description:
Attempting to retrieve a links's name by index in the case
where the link is external and the file that the object is
located in doesn't exist was causing a segmentation fault
(in production) and an assertion failure (in debug).
The segfault wasn't occuring until the metadata accumulator
attempted a write, so I've added error checking higher in
the pipeline in H5O_protect (where there was previously just
an assert) to catch this. I've also added additional asserts
in the H5F layer where there were none.
Additionally, I added another case to the links.c test to
test that this fails gracefully instead of segfaulting or
asserting out.
Tested:
h5committest and gandalf (mac os x)
