[svn-r19798] 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)
