[krbdev.mit.edu #2942] CVS Commit

There seems to be a problem with a null pointer popping up when
profile_node_iterator reads ...->data->root to start walking through the
contents.  Don't have a lot of details, but I've got some patches that might
tighten things up a little.

* prof_tree.c (profile_node_iterator): Check that the root node pointer is not
null; raise assertion failure if it is.

* prof_int.h: Include k5-platform.h.
(struct _prf_data_t): Reorder fields, and insert some padding.

* prof_file.c (scan_shared_trees_locked): Check that the "root" field isn't
null.
(profile_open_file): Update the in-memory file contents after updating the
refcount instead of before.
(profile_update_file_data): If the root node in the file data is null, always
do the update.  Check that it's not null before returning a success
indication.
(profile_dereference_data_locked): Scan linked list of file data objects for
sanity check, before and after.
(profile_dereference_data_locked): Don't do it here.
