The cache type specific differencies among afs_MemCacheStoreProc
and afs_UFSCacheStoreProc are divided into two sets of "storeOps".
Upon rxfs_storeInit, the appropriate set is chosen.
FIXME: Simon suggests that there should be a single set of storeOps,
as the main difference lies in what rx_ calls must be made.
This decision would then be made by calling a wrapper function from
each storeOp. These wrappers should be cachetype-specific and protocol-
independent. They would be associated to struct afs_cacheOps.

Rework dependencies in src/bubasics to prevent needless rebuilding and

have to be avoided.
Remove dependency on the include/afs directory from the src/config Makefile.
Depending on a directory means that we will rebuild the target if the

installed. This caused param.h to get re-installed in some cases and
the kernel module source files to be recompiled. This directory is
created in the top-level Makefile anyway so we shouldn't need an

This commit creates or modifies multi-threaded versions of various
