[PATCH RESEND 0/7] migration pending patches

[Fabiano Rosas]

Hi, this is a resend of a few patches that lingered behind in the past
months. They are all reviewed and tested.

patch 1 is the test for the file transport which missed the last pull;

patches 2-6 are two small refactorings to ram.c that are prerequisite
for the fixed ram work;

patch 7 enables the multifd cancel test which has been fixed for a
while now since commit 01ec0f3a92 ("migration/multifd: Protect
accesses to migration_threads").

CI run: https://gitlab.com/farosas/qemu/-/pipelines/1033679993

Thanks!
