b17fd211e2 testQEMUSchemaValidateCommand: Add possibility for partial QMP validation
The QMP schema for 'device_add' is not complete yet. Allow validation of
incomplete schema so that we can enable at least some validation. Once
there's more schema in the future all present members are still
validated.

8fbffeae07 qemu: Decrease scope of variables in qemuConnectGetAllDomainStats()
There are two variables (@vm and @domflags) in qemuConnectGetAllDomainStats()
that are used only within the for() loop but declared for entire function.
Bring them into the loop to make it obvious they are not used outside of it.

2703b0b5bf qemu: Do not report eof when processing monitor IO
There have been countless reports from users concerned about the following
error reported by libvirtd when qemu domains are shutdown

internal error: End of file from qemu monitor

While the error is harmless, users often mistaken it for real problem with
their deployments. EOF from the monitor can't be entirely ignored since
other threads may be using the monitor and must be able to detect the EOF
condition.

One potential fix is to delay reporting EOF until the monitor is used
after EOF is detected. This patch adds a 'goteof' member to the
qemuMonitor structure, which is set when EOF is detected on the monitor
socket. If another thread later tries to send data on the monitor, the
EOF error is reported.

44d8324f13 virnetsocket: Don't free virCommand in virNetSocketNewConnectCommand()
The aim of virNetSocketNewConnectCommand() is to execute passed
command and attach socket pair/pipe to it so that client socket
can be opened (this is used for connections with alternative
transports, e.g. ssh). The virCommand is created in a caller and
then passed to virNetSocketNewConnectCommand() where it is freed
using virCommandFree(). This approach is wrong on two levels:

1) The deallocation happens on a different level than allocation,
2) There's a WIN32 stub that just reports an error and doesn't
   free the command.

However, with g_autoptr() trickery the command can be freed in
caller.
