Rather than having a 'free_entry' member that can be called to free an
hdb_entry, we now implement the free function in HDB. We perform the
free only if the context pointer is non-NULL.
We also remove the ZERO_STRUCTP() in sdb_entry_to_hdb_entry(), as the
context pointer is now part of the 'hdb_entry' structure itself, and
this would undesirably zero it out.
This is an adaptation to Heimdal commits:

hdb: decorate HDB_entry with context member
Decorate HDB_entry with context and move free_entry callback into HDB structure
itself. Requires updating hdb_free_entry() signature to include HDB parameter.
A follow-up commit will consolidate hdb_entry_ex (which has a single hdb_entry
member) into hdb_entry.

hdb: eliminate hdb_entry_ex
Remove hdb_entry_ex and revert to the original design of hdb_entry (except with
an additional context member in hdb_entry which is managed by the free_entry
method in HDB).
NOTE: THIS COMMIT WON'T COMPILE/WORK ON ITS OWN!
