Running bootstrap and autoreconf from autogen.sh produced different
files in build-aux directory. The reason is that gnulib usually have
newer version of these files and overwrites them after the autoreconf
step.
In order to fix it remove the --install and --force options, in addition
introduce --verbose option in order to reflect what bootstrap is doing.

Remove many imports of sys/ioctl.h which are redundant,
and conditionalize remaining usage that needs to compile
on Windows platforms.
The previous change to remove the "nonblocking" gnulib
module indirectly caused the loss of the "ioctl" gnulib
module that we did not explicitly list in bootstrap.conf
despite relying on.
Rather than re-introduce the "ioctl" module this patch

Libvirt's original atomic ops impls were largely copied
from GLib's code at the time. The only API difference
was that libvirt's virAtomicIntInc() would return a
value, but g_atomic_int_inc was void. We thus use
g_atomic_int_add(v, 1) instead, though this means
virAtomicIntInc() now returns the original value,
instead of the new value.
This rewrites libvirt's impl in terms of g_atomic_int*
as a short term conversion. The key motivation was to
quickly eliminate use of GNULIB's verify_expr() macro
which is not a direct match for G_STATIC_ASSERT_EXPR.
Long term all the callers should be updated to use
g_atomic_int* directly.

Windows sockets take a SOCKET HANDLE object instead of a
file descriptor. Wrap them in the same way that gnulib
does so that they use C runtime file descriptors.
While we could in theory use GSocket, it is hard to get
the exact same semantics libvirt has for its current
socket usage. Wrapping the Winsock2 APIs is thus the
easiest approach in the short term.
In changing the socke wrappers we need to re-implement
the nonblocking function too, since the GNULIB impl
expects to be used with the GNULIB sockets wrappers.

In order to avoid holding an agent job and a normal job at the same
time, we want to avoid accessing the domain's definition while holding
the agent job. To achieve this, qemuAgentGetFSInfo() only returns the
raw information from the agent query to the caller. The caller can then
release the agent job and then proceed to look up the disk alias from
the vm definition. This necessitates moving a few helper functions to
qemu_driver.c and exposing the agent data structure (qemuAgentFSInfo) in
the header.
In addition, because the agent function no longer returns the looked-up
disk alias, we can't test the alias within qemuagenttest. Instead we
simply test that we parse and return the raw agent data correctly.

Update the host CPU code to report the die_id in the NUMA topology
capabilities. On systems with multiple dies, this fixes the bug
where CPU cores can't be distinguished:
<cpus num='12'>
<cpu id='0' socket_id='0' core_id='0' siblings='0'/>
<cpu id='1' socket_id='0' core_id='1' siblings='1'/>
<cpu id='2' socket_id='0' core_id='0' siblings='2'/>
<cpu id='3' socket_id='0' core_id='1' siblings='3'/>
</cpus>
Notice how core_id is repeated within the scope of the same socket_id.
It now reports
<cpus num='12'>
<cpu id='0' socket_id='0' die_id='0' core_id='0' siblings='0'/>
<cpu id='1' socket_id='0' die_id='0' core_id='1' siblings='1'/>
<cpu id='2' socket_id='0' die_id='1' core_id='0' siblings='2'/>
<cpu id='3' socket_id='0' die_id='1' core_id='1' siblings='3'/>
</cpus>
So core_id is now unique within a (socket_id, die_id) pair.

However, the code was effective on both sides of migration resulting in
