ntdb: enhancement to allow direct access to the ntdb map during expansion.
This means keeping the old mmap around when we expand the database.
We could revert to read/write, except for platforms with incoherent
mmap (ie. OpenBSD), where we need to use mmap for all accesses.
Thus we keep a linked list of old maps, and unmap them when the last access
finally goes away.
This is required if we want ntdb_parse_record() callbacks to be able
to expand the database.
