util: hash: Add delete-safe hash iterator

'virHashForEach' historically allowed deletion of the current element as
'virHashRemoveSet' didn't exist. To prevent us from having to deeply
analyse all iterators add virHashForEachSafe which first gets a list of
elements and iterates them outside of the hash table.

This will allow replace the internals of the hash table with other
implementation which don't allow such operation.
