src: rework of the hash-cache infrastructure
Currently, the caching system is implemented in a two layer architecture: hashtable (inner layer) and cache (upper layer). This patch reworks the hash-cache infrastructure to solve some initial design problems to make it more flexible, the main strong points of this patch are: * Memory handling is done in the cache layer, not in the inner hashtable layer. This removes one of the main dependencies between the hashtable and the cache classes. * Remove excessive encapsulation: the former cache used to hide a lot of details of the inner hashtable implementation. * Fix over-hashing of some operations: lookup-delete-add required three hash calculations. Similarly, the update-or-add operation required two hash calculations. Now, we calculate the hash once and re-use the value how many times as we need. This patch simplifies the caching system. As a result, we save ~130 lines of code. Small code means and less complexity means less chance to have bugs. Signed-off-by: Pablo Neira Ayuso <>
