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.

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:

When KVM is not available, the i386 migration test also runs in a rather
slow fashion, since the guest code takes a couple of seconds to print

The migration tests spend a lot of time waiting for a sign of live
of the guest on the serial console. The aarch64 migration code only
outputs "B"s every couple of seconds (at least it takes more than 4
seconds between each characeter on my x86 laptop). There are a lot
of migration tests, and if each test that checks for a successful
migration waits for these characters before and after migration, the
wait time sums up to multiple minutes! Let's use a shorter delay to
speed things up.
While we're at it, also remove a superfluous masking with 0xff - we're
reading and storing bytes, so the upper bits of the register do not
matter anyway.
With these changes, the test runs twice as fast on my laptop, decreasing
the total run time from approx. 8 minutes to only 4 minutes!

Several changes:
- We only allow generate header "inside" the tree. Why? Because we
need to connit the result, so it makes no sense to generate them on
the build dir.
- We only generate a single target each time. Getting all the
cross-compilers correctly is an impossible task. So know you do:
make -C tests/migration $target (native)
make CROSS_PREFIX=foo- -C tests/migratiion $target (cross)
And you are done.
- If we are building out of tree, we have no data about if we are
cross-compile or whatever. So instead of guess what is happening,
just do what I pointed on previous point.

We can re-use the s390-ccw bios code to implement a small firmware
for a s390x guest which prints out the "A" and "B" characters and
modifies the memory, as required for the migration test.

Fixed up Makefile since the aarch patch sneaked in first
This patch adds migration test support for aarch64. The test code, which
implements the same functionality as x86, is booted as a kernel in qemu.
Here are the design choices we make for aarch64:
* We choose this -kernel approach because aarch64 QEMU doesn't provide a
built-in fw like x86 does. So instead of relying on a boot loader, we
use -kernel approach for aarch64.
* The serial output is sent to PL011 directly.
* The physical memory base for mach-virt machine is 0x40000000. We change
the start_address and end_address for aarch64.
In addition to providing the binary, this patch also includes the source
code and the build script in tests/migration/aarch64. So users can change
the source and/or re-compile the binary as they wish.

This reverts commit 0ea47d0f36.
scripts/argparse.py was removed from the tree, so we don't
need this hack anymore.

Recently a new configure option, CROSS_CC_GUEST, was added to
$(TARGET)-softmmu/config-target.mak to support TCG-related tests. This
patch tries to leverage this option to support cross compilation when the
migration boot block file is being re-generated:
* The x86 related files are moved to a new sub-dir (named ./i386).
* A new top-layer Makefile is created in tests/migration/ directory.
This Makefile searches and parses CROSS_CC_GUEST to generate CROSS_PREFIX.
The CROSS_PREFIX, if available, is then passed to migration/$ARCH/Makefile.

The x86 boot block header currently is generated with a shell script.
To better support other CPUs (e.g. aarch64), we convert the script
into Makefile. This allows us to 1) support cross-compilation easily,
and 2) avoid creating a script file for every architecture.
Note that, in the new design, the cross compiler prefix can be specified by
setting the CROSS_PREFIX in "make" command. Also to allow gcc pre-processor
to include the C-style file correctly, it also renames the
x86-a-b-bootblock.s file extension from .s to .S.

The boot block used in the migration test is currently only
shipped as a hex (with the source in the git commit message of ea0c6d62),
change this to actually include the source.
A script is added to rebuild the header but the expectation is that
the generated hex is shipped as well as the .s, so that
there's no requirement to have just the right assembler etc.
