> Eliminate FSFS format 7 CPU overhead from svnadmin.

> This introduces a simply threshold value for the cache sizes above
> which we will enable block-read.
>
> While svnadmin is the ideal application for "block-read" (read all
> repo data somewhat linearly and use virtually all of it), the very
> small default cache sizes are simply not enough to benefit from it.
> As a result, hit rates drop even further.
>
> For larger caches, the feature equalizes most of the structural
> disadvantage that packed f7 repos have over f6 (f6 is in revision
> order and svnadmin is the only tool to read it in that ordering).
> For smaller caches, only meta data and certain temporary objects
> get cache while we heavily rely on the OS disk cache to provide
> us with data. This is equally true for all FSFS formats.
As you probably found out by now (on all buildbots):
