9bb3571f10 bootstrap: remove 26 more gnulib modules
* send, recv: we use write & read for sockets so don't
   need these portability wrappers
 * ioctl, fcntl, fcntl-h: any usage of these is conditionally
   compiled and excludes Windows
 * ttyname_r: this exists in all supported platforms that
   we require now
 * environ: the tests explicitly declare this global variable
 * intprops: the code has been converted / simplified
 * nonblocking: we have a custom impl now to work with our
   own sockets wrappers
 * openpty: custom checks in configure.ac cope with portability
 * accept, bind, connect, getpeername, getsockname, listen,
   setsockopt, socket: code needing Windows portability uses
   our wrapper functions
 * close: avoids abort when passed invalid FD on Windows.
   Our VIR_FORCE_CLOSE wrapper avoids calling close(-1)
   and it is reasonable to abort in other scenarios in
   the RPC client
 * physmem: the gnulib code has been partially imported
 * warnings, manywarnings: copy the files directly into
   our local m4 dir
 * verify: replaced by G_STATIC_ASSERT
 * pthread_sigmask: none of the fixed portability problems
   affect libvirt's usage on current supported platforms
 * termios: the header is now conditionally included only
   when needed
 * time_r: replaced with GDateTime APIs

3caa28dc50 src: replace gmtime_r/localtime_r/strftime with GDateTime
gmtime_r/localtime_r are mostly used in combination with
strftime to format timestamps in libvirt. This can all
be replaced with GDateTime resulting in simpler code
that is also more portable.

There is some boundary condition problem in parsing POSIX

7c828af858 src: conditionally exclude cfmakeraw/termios.h on WIN32
The GNULIB termios module ensures termios.h exists (but
is none the less empty) when building for Windows. We
already exclude usage of the functions that would exist
in a real termios.h, so having an empty termios.h is
not especially useful.

It is simpler to just put all use of termios.h related
functions behind a "#ifndef WIN32" conditional.

7b9645a7d1 util: replace atomic ops impls with g_atomic_int*
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.

b5c95d042b util: introduce compat wrappers for Winsock2
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.

3c436c22a4 qemu: remove qemuDomainObjBegin/EndJobWithAgent()
This function potentially grabs both a monitor job and an agent job at
the same time. This is problematic because it means that a malicious (or
just buggy) guest agent can cause a denial of service on the host. The
presence of this function makes it easy to do the wrong thing and hold
both jobs at the same time. All existing uses have already been removed
by previous commits.

599ae372d8 qemu: don't access vmdef within qemu_agent.c
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.

0169f5ecde tests: add host CPU data files for validating die_id
Only Cascadelake-AP CPUs appear to report "die_id" values != 0 on Linux
right now - AMD EPYC's don't report "die_id" (at least with Fedora 31
kernel). Lacking access to Cascadelake-AP CPUs, this test data was from
a Fedora 31 QEMU guest launched with

 -cpu qemu64 -smp sockets=2,dies=3,cores=2,threads=1

Ideally we'd replace this data with some from a real machine reporting
"die_id", to ensure we're not mislead by QEMU's impl.

7b79ee2f78 hostcpu: add support for reporting die_id in NUMA topology
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.

This adds support for "dies" in the XML parser, with the value

bd04d63ad9 qemu: Don't emit SUSPENDED_POSTCOPY event on destination
When pause-before-switchover QEMU capability is enabled, we get STOP
event before MIGRATION event with postcopy-active state. To properly
handle post-copy migration and emit correct events commit
v4.10.0-rc1-4-geca9d21e6c added a hack to
qemuProcessHandleMigrationStatus which translates the paused state
reason to VIR_DOMAIN_PAUSED_POSTCOPY and emits
VIR_DOMAIN_EVENT_SUSPENDED_POSTCOPY event when migration state changes
to post-copy.

However, the code was effective on both sides of migration resulting in
a confusing VIR_DOMAIN_EVENT_SUSPENDED_POSTCOPY event on the destination
host, where entering post-copy mode is already properly advertised by
VIR_DOMAIN_EVENT_RESUMED_POSTCOPY event.

it to machined.
