68aade07c705f3938d2a9d7a204588fcc505124d [scudo][standalone] Release secondary memory on purge
Summary:
The Secondary's cache needs to be released when the Combined's
`releaseToOS` function is called (via `M_PURGE`) for example,
which this CL adds.
Additionally, if doing a forced release, we'll release the
transfer batch class as well since now we can do that.
There is a couple of other house keeping changes as well:
- read the page size only once in the Secondary Cache `store`
- remove the interval check for `CanRelease`: we are going to
make that configurable via `mallopt` so this needs not be
set in stone there.
