by RAIDframe. Convert all other RAIDframe global pools to use pools defined within this new structure. - Introduce rf_pool_init(), used for initializing a single pool in RAIDframe. Teach each of the configuration routines to use rf_pool_init(). - Cleanup a few pool-related comments. - Cleanup revent initialization and #defines. - Add a missing pool_destroy() for the reconbuffer pool. (Saves another 1K off of an i386 GENERIC kernel, and makes stuff a lot more readable)
