If the maximum number of open file descriptors is much greater than the
usual 1024 (for example inside a Docker container), the performance
drops significantly.
This was reported upstream in:
https://bugzilla.redhat.com/show_bug.cgi?id=1537564
which resulted in:
https://github.com/rpm-software-management/rpm/pull/444
The pull request above has now been integrated and this commit contains
a backport of its three patches, which together change the behavior of
rpm so that its performance is now independent of the maximum number of
open file descriptors.
