[OpenAFS] dynamic allocation of vcaches

We have a patch (in RT 124344) for adding support to Linux for dynamic
allocation of vcaches rather than the current hard limit provided by
the -stat flag to afsd.  It currently does not have a command-line
argument to turn it on (i.e., if the patch is applied, you get dynamic
support), and I want to make sure the interface we provide is a
reasonable one.  I propose:

afsd -stat <N> -dynamic-vcaches

where N would be the initial value of the number of vcache entries but
that the cache manager could dynamically allocate as many as needed).

Any concerns with that feature and interface?
