This series fixes an issue where the outcome of the migration qtest
relies on the initial memory contents all being the same across the
first 100MiB of RAM, which is a very fragile invariant.
We fix this by making sure we zero the first byte of every testable page
in range beforehand.
Changes since v1:
- Add a fix for the s390x test binary as well as suggested by Peter Xu
Daniil Tatianin (3):
i386/a-b-bootblock: factor test memory addresses out into constants
i386/a-b-bootblock: zero the first byte of each page on start
s390x/a-b-bios: zero the first byte of each page on start

So that we have less magic numbers to deal with. This also allows us to
reuse these in the following commits.

The migration qtest all the way up to this point used to work by sheer
luck relying on the contents of all pages from 1MiB to 100MiB to contain
the same one value in the first byte initially.
This easily breaks if we reduce the amount of RAM for the test instances
from 150MiB to e.g 110MiB since that makes SeaBIOS dirty some of the
pages starting at about 0x5dd2000 (~93 MiB) as it reuses those for the
HighMemory allocator since commit dc88f9b72df ("malloc: use large
ZoneHigh when there is enough memory").
This would result in the following errors:
12/60 qemu:qtest+qtest-x86_64 / qtest-x86_64/migration-test ERROR 2.74s killed by signal 6 SIGABRT
stderr:

and in another 26 pages**
ERROR:../tests/qtest/migration-test.c:300:check_guests_ram: assertion failed: (bad == 0)
Fix this by always zeroing the first byte of each page in the range so
that we get consistent results no matter the initial contents.

Same as with the x86 verison of this test, we relied on the contents of
all pages in RAM to be the same across the entire test range, which is
very fragile. Zero the first byte of each page before running the
increment loop to fix this.
