Laurent Vivier 61ae5cf3a2 libqos: use generic qtest_shutdown()
Machine specific shutdown function can be registered by
the machine specific qtest_XXX_boot() if needed.

So we will not have to test twice the architecture (on boot and on
shutdown) if the test can be run on several architectures.

Laurent Vivier e49f827725 tests: fix qvirtqueue_kick
vq->avail.idx and vq->avail->ring[] are a 16bit values,
so read and write them with readw()/writew() instead of
readl()/writel().

To read/write a 16bit value with a 32bit accessor works fine
on little-endian CPU but not on big endian CPU.

Zhang Shuai <zhangshuai13@huawei.com>.

Stefan Hajnoczi ee3b850a70 libqos: drop duplicated virtio_ring.h bit definitions
Note that virtio_ring.h defines feature bits using their bit number:

  #define VIRTIO_RING_F_INDIRECT_DESC     28

On the other hand libqos virtio.h uses the bit mask:

  #define QVIRTIO_F_RING_INDIRECT_DESC    0x10000000

The patch makes the necessary adjustments.

I have used "1u << BITMASK" instead of "1ULL << BITMASK" because the
64-bit feature fields are not implemented in libqos virtio.

qpci_pc_iomap() maps BARs one after the other, without padding.  This
is wrong.  PCI Local Bus Specification Revision 3.0, 6.2.5.1. Address
Maps: "all address spaces used are a power of two in size and are
naturally aligned".  That's because the size of a BAR is given by the
number of address bits the device decodes, and the BAR needs to be
mapped at a multiple of that size to ensure the address decoding
works.

Fix qpci_pc_iomap() accordingly.  This takes care of a FIXME in
ivshmem-test.

John Snow 95ea663693 libqos/ahci: fix memory management bugs
There's a handful of trivial bugs in the libqos/ahci functions,
squish them together.

- Zero cached pointers after freeing them
- The Command List Buffer is an array of 32x 32 byte structures, not
  32x 8 byte pointers -- it's 1MiB, not 256 bytes. Zero it ALL.
- Free the correct command in ahci_pick_cmd.

John Snow 91d0374a7f libqos/ahci: Swap memread/write with bufread/write
Where it makes sense, use the new faster primitives.
For generally small reads/writes such as for the PRDT
and FIS packets, stick with the more wasteful but
easier to debug memread/memwrite.

For ahci-test (before migration tests):
With this patch:
real    0m3.675s
user    0m2.582s
sys     0m1.718s

Without any qtest protocol improvements:
real    0m14.171s
user    0m12.072s
sys     0m12.527s

John Snow 88e21f9485 qtest/ahci: add migrate dma test
Write to one guest, migrate, and then read from the other.
adjust ahci_io to clear any buffers it creates, so that we
can use ahci_io safely on both guests knowing we are using
empty buffers and not accidentally re-using data.

John Snow 085248ae87 libqos: Add migration helpers
libqos.c:
    -set_context for addressing which commands go where
    -migrate performs the actual migration

malloc.c:
    - Structure of the allocator is adjusted slightly with
      a second-tier malloc to make swapping around the allocators
      easy when we "migrate" the lists from the source to the destination.
