Add comma escaping for netsource. This is done here because
qemuBuildNetworkDriveStr has other external callers which
may not expect an escaped comma; however, this particular
command building path needs to perform the escaping for the
hostdev command line, so we do it now to ensure src->path
and src->host->name are covered.

If a thread is unable to acquire a job (e.g. because of timeout)
an error is reported and the error message contains reference to
the other thread holding the job. Well, the error message should
report agent job too as it is yet another source of possible
failure.

If a <interface> includes a filter name but the nwfilter driver is not
present we silently do nothing. This is very bad, because an application
that thinks it is protected by malicious guest traffic will in fact be
vulnerable. Reporting an error gives the administrator the ability to
know there is a problem and fix it.

As qemuMonitorJSONIOProcess will call qemuMonitorJSONIOProcessEvent
which unlocks the monitor mutex, there is some extreme situation,
eg qemu send message to monitor twice in a short time, where the
local viriable 'msg' of qemuMonitorIOProcess could be a wild point:
1. qemuMonitorSend() assign mon->msg to parameter 'msg', which is alse a
local variable of its caller qemuMonitorJSONCommandWithFd(), cause
eventloop to send message to monitor, then wait condition.
2. qemu send message to monitor for the first time immediately.
3. qemuMonitorIOProcess() is called, then wake up the qemuMonitorSend()
thread, but the qemuMonitorSend() thread stuck for a while as cpu pressure
or some other reasons, which means the qemu monitor is still unlocked.
4. qemu send event message to monitor for the second time,
such as RTC_CHANGE event
5. qemuMonitorIOProcess() is called again, the local viriable 'msg' is
assigned to mon->msg.
6. qemuMonitorIOProcess() call qemuMonitorJSONIOProcess() to deal with
the qemu event.
7. qemuMonitorJSONIOProcess() unlock the qemu monitor in the macro
'QEMU_MONITOR_CALLBACK', then qemuMonitorSend() thread get the mutex
and free the mon->msg, assign mon->msg to NULL.

Re-generating of generated source files in the hyperv directory
depends on src/.hyperv_wmi_generator.stamp not existing, or having a
timestamp older than src/hyperv/hyperv_wmi_generator.py. "make
maintainer-clean" erases the generated files, but not this sentinel
file, so the erased files aren't regenerated during the next
make. Once we add it to the list of MAINTAINERCLEANFILES, it gets
deleted at the same time as the generated files, so make is able to

Attempting to use the FORCE flag for snapshot-revert was resulting
in failures because qemuProcessStart and qemuProcessStartCPUs were
using QEMU_ASYNC_JOB_START after a qemuProcessStop resulting in an
error when entering the monitor:
error: internal error: unexpected async job 6 type expected 0
So create a local @jobType, initialize to QEMU_ASYNC_JOB_START, and
change to QEMU_ASYNC_JOB_NONE if we end up in the --force path
where the qemuProcessStop is run before a Start and StartCPUs.
