Implement io.buffer for fast IO (work in progress)
Rewrite util/cache.c and use it form io/buffer.c
Refactor util/ht.c and util/ht64.c to reuse code
Various minor fixes in RIO api
cache.c must be rewritten into r_buf for
- Kinda smart (150LOC)
- Fork it for 64bit hash keys (make ht64 in libr/util)
* Make RConfig use the RHashTable to resolve by name
- Code cleanup resulting in -30LOC
- O(1) access to config variables (speedup!)
- Make r_list_free and r_list_destroy take sense
