* New implementation of lcr part of lcr module.

* Entries of lcr table are now stored in in-memory cache for high
  performance (see README for execution times of lcr related functions).
* Gateways can now be assigned a weight within their groups.
* Support for prefix_mode=1 has been dropped.
* lcr_dump MI function has been split into lcr_gw_dump and lcr_lcr_dump
  functions.
* lcr_reload function is now executed under a lock.
* Testing is welcomed.
