And allow preallocation of file-based memory even without -mem-prealloc.
Some care is necessary because -mem-prealloc does not allow disabling
preallocation for hostmem-file.

maybe 'prealloc' property should belong to hostmem-file instead of the
abstract hostmem.
No, prealloc makes sense even in hostmem-ram (especially in combination with "-realtime mlock").
