  exec: Ensure the only one cpu_index allocation method is used

Make sure that cpu_index auto allocation isn't used in
combination with manual cpu_index assignment. And
dissallow out of order cpu removal if auto allocation
is in use.

Target that wishes to support out of order unplug should
switch to manual cpu_index assignment. Following patch
could be used as an example:
 (pc: init CPUState->cpu_index with index in possible_cpus[]))

  Log Message:
  -----------
  vhost-user-test: Use libqos instead of pxe-virtio.rom

vhost-user-test relies on iPXE just to initialize the virtio-net
device, and doesn't do any actual packet tx/rx testing.

In addition to that, the test relies on TCG, which is
imcompatible with vhost. The test only worked by accident: a bug
the memory backend initialization made memory regions not have
the DIRTY_MEMORY_CODE bit set in dirty_log_mask.

This changes vhost-user-test to initialize the virtio-net device
using libqos, and not use TCG nor pxe-virtio.rom.

  -----------
  vl: Delay initialization of memory backends

Initialization of memory backends may take a while when
prealloc=yes is used, depending on their size. Initializing
memory backends before chardevs may delay the creation of monitor
sockets, and trigger timeouts on management software that waits
until the monitor socket is created by QEMU. See, for example,
the bug report at:
https://bugzilla.redhat.com/show_bug.cgi?id=1371211

In addition to that, allocating memory before calling
configure_accelerator() breaks the tcg_enabled() checks at
memory_region_init_*().

This patch fixes those problems by adding "memory-backend-*"
classes to the delayed-initialization list.
