This generic caching module is better than the ad-hoc code we used in
getkey.c. More cleanup in getkey is still required but it is a
start. There is also a small performance increase with the new cache:
With a large keyring and --list-sigs I get these numbers:
| | before | after |
|------+------------+------------|
| real | 14m1.028s | 12m16.186s |
| user | 2m18.484s | 1m36.040s |
| sys | 11m42.420s | 10m40.044s |
Note the speedup in the user time which is due to the improved cache
algorithm. This is obvious, because the old cache was just a long
linked list; the new cache are two hash tables.
