[Libguestfs] [PATCH 0/3] tests: Various fixes for btrfs and aarch64.

These patches fix btrfs on aarch64.  You still need btrfs-progs 4.4
which was only released a few days ago.

[Libguestfs] [PATCH 1/3] tests: Increase the size of the /dev/sda and /dev/sdb test devices.

Previously these were rather small - just 500 MB.  This is too small
to create a btrfs device on aarch64 (where page size may be 64K), and
barely enough even on x86-64.  This change makes both these devices
10 GB, and adjusts a few tests so they continue to pass.

[Libguestfs] [PATCH 2/3] tests: btrfs: Don't test --leafsize, and use --nodesize 64K.

In btrfs-progs 4.4, the --leafsize parameter is deprecated.  It's now
just an alias for --nodesize.

On aarch64, --nodesize 4096 does not work because it's smaller than
the page size (64K).  Luckily we can test a 64K nodesize on any
platform, so use that instead.

[Libguestfs] [PATCH 3/3] tests: btrfs: Use a 2000 MB partition for btrfs test (instead of 200 MB).

One of the mkfs-btrfs tests used two 200 MB partitions.  That isn't
enough to create a btrfs filesystem on aarch64 (with 64K page size).
Since we now have a 10 GB disk, we can make the test partition 10
times larger.

Sorry, just realized I didn't update the documentation correctly.
These should obviously say 10GB.
