While working on the dynamic shared memory registry, I noticed a couple of
potential improvements for code that uses dshash tables.
* A couple of dshash_create() callers pass in 0 for the "void *arg"
parameter, which seemed weird. I incorrectly assumed this was some sort
of flags parameter until I actually looked at the function signature.
IMHO we should specify NULL here if arg is not used. 0001 makes this
change. This is admittedly a nitpick.
* There are no dshash compare/hash functions for string keys. 0002
introduces some that simply forward to strcmp()/string_hash(), and it
uses them for the DSM registry's dshash table. This allows us to remove
the hacky key padding code for lookups on this table.
Thoughts?
