VPP-189 Tweak hash_foreach_pair to avoid static warning
Coverity doesn't like when an incrementing pointer is taken from the address of a singleton; it cries that this is a potential buffer overrun. Since the cases of this in hash_foreach_pair are based on items from a simple union used just to have different types point to the same location it's a simple matter of using the pointer to that location directly. Since we then aren't using the members of the union, we can change that to an opaque pointer (void *). This accounts for >60 issues in Coverity. Whilst here, convert some useful existing comments into a docblock. Change-Id: I114183ab7d7948d4a6a703451417f79fa37634eb Signed-off-by: Chris Luke <chrisy@flirble.org>
