When trying to reuse a memchunk, avoid locking the handle when we easily know that a transfer is needed and thus we will not afford doing it

Disable forcing available memory by default, since this makes StarPU spuriously free data when prefetching fills the memory. Clean buffers are enough to be able to allocate data easily anyway.

Improve data reuse: before calling generic reclaiming, try to reuse potentially-in-use mc of the same interface. Avoids having generic reclaiming free data just to be able to reallocate exactly the same kind of data

Fix setting diduse for a memory chunk: _starpu_memchunk_recently_used does not necessarily mean it was actually used, that could be a prefetch only. Make diduse marked from the tasks and from the data acquisitions instead

Fix and test the case where we try to invalidate a data which has some transfers pending. Also make sure that eviction doesn't evict a data being invalidated

Do not trigger reclaiming at all if there is enough room in a memory node, even if all its data are dirty. That's needed behavior for e.g. stencils
