util/disk_cache: Add new mesa-db cache type Introduce new cache type, the Mesa-DB. This is a single-file read/write cache that is based on the read-only Fossilize DB cache. Mesa-DB supports cache size capping. It's a much more efficient cache than the multi-file cache because Mesa-DB doesn't have the inode overhead. The plan is to make Mesa-DB the default cache implementation once it will be deemed as stable and well tested. For now users have to set the new MESA_DISK_CACHE_DATABASE environment variable in order to active the Mesa-DB cache. Mesa-DB cache is resilient to corrupted cache files and doesn't require maintenance from users and developers. The size capping is implemented by evicting least recently used cache items and compacting the cache database files with the evicted entries. In order to prevent frequent compaction of the cache, at minimum a half of cache is evicted when cache is full.
