##Features
- based on leveldb lru cache
- thread safe
- max key size: 64 (can modify cache.h:KEY_MAX_SIZE by yourself)
- support unfixed length value and fixed length value
##Usage
// create cache.
// leveldb_cache_t *lcache = leveldb_cache_create_lru(10000, -1); // unfixed length value.
leveldb_cache_t *lcache = leveldb_cache_create_lru(10000, 32); // fixed length value.
// insert entry.
leveldb_cache_insert(lcache, "key", strlen("key"), "value", strlen("value"));
// fix entry.
void *handle = leveldb_cache_fix(lcache, "key", strlen("key"));
// get value.
size_t vlen = 0;
char *v = leveldb_cache_value(lcache, handle, &vlen);
// unfix entry.
leveldb_cache_unfix(lcache, handle);
// erase entry.
leveldb_cache_erase(lcache, "key", strlen("key"));
// destory cache.
leveldb_cache_destroy(lcache);
