If the delivery of the DEVICE_DELETED event for the vCPU being deleted
would time out, the code would not call 'qemuDomainResetDeviceRemoval'.

Since the waiting thread did not unregister itself prior to stopping the
waiting the monitor code would try to wake it up instead of dispatching
it to the event worker. As a result the unplug process would not be
completed and the definition would not be updated.

Note that the waiting thread is signaled in the debug logs to simplify
debugging.

This reverts commit c96bd78e.

So our code is one big mess and we modify domain definition while
building qemu_command line and our hotplug code share only part
of the parsing and command line building code.  Let's revert
that change because to fix it properly would require refactor and
move a lot of things.

Even though scsi storage driver builds fine on non-Linux, it
will not work properly because it relies on Linux procfs, so
disable that in configure if we're not building for Linux.

We should skip <listen type='socket'/> only if the 'socket' path
is specified because if there is no 'socket' path we need to
keep that element in migratable XML.

When libvirtd is started we call qemuDomainRecheckInternalPaths
to detect whether a domain has VNC socket path generated by libvirt
based on option from qemu.conf.  However if we are parsing status XML
for running domain the existing socket path can be generated also if
the config XML uses the new <listen type='socket'/> element without
specifying any socket.

The current code doesn't make difference how the socket was generated
and always marks it as "fromConfig".  We need to store the
"autoGenerated" value in the status XML in order to preserve that
information.

The difference between "fromConfig" and "autoGenerated" is important
for migration, because if the socket is based on "fromConfig" we don't
print it into the migratable XML and we assume that user has properly
configured qemu.conf on both hosts.  However if the socket is based
on "autoGenerated" it means that a new feature was used and therefore
we need to leave the socket in migratable XML to make sure that if
this feature is not supported on destination the migration will fail.

Some of our tests (e.g. qemuhotplugtest) call
virDomainSaveConfig(). Now the problem is, qemuTestDriverInit()
creates a fake qemu driver and fills it with some fake
configuration. At least so we hoped. The truth is, it calls
regular virQEMUDriverConfigNew() and then fix couple of paths.
Literally. Therefore our tests see regular stateDir and configDir
for the user that is running the tests. Directories, where live
domain XMLs are stored. Let's just hope our test suite hasn't
mangled any of them.

When we are restoring a domain from a saved image, or just
updating its XML in the saved image - we have to make sure that
the ABI guests sees will not change. We have a function for that
which reports errors. But for some reason if this function fails,
we call it again with slightly different argument. Therefore it
might happen that we overwrite the original error and leave user
with less helpful one.

Use "virNWFilterObj" as a prefix for any external API in virnwfilterobj

In an effort to be consistent with the source module, alter the function
prototypes to follow the similar style of source with the "type" on one
line followed by the function name and arguments on subsequent lines with
with argument getting it's own line.

Alter the format of the code to follow more recent style guidelines of
two empty lines between functions, function decls with "[static] type"
on one line followed by function name with arguments to functions each
on one line.

Move all the NWFilterObj API's into their own module virnwfilterobj
from the nwfilter_conf

Purely code motion at this point, plus adjustments to cleanly build.

Rather than pass the nwfilter object, just pass the def to the function

There's no need to pass the driver pointer to nwfilter_conf, just
pass the configDir.

Found by Coverity. Because there's an "if ((cur = strstr(base, "revision"))
 != NULL) {" followed by a "base = cur" coverity notes that 'base' could
then be NULL causing the return to the top of the "while ((tmp_base =
strstr(base, "processor")) != NULL) {" to have strstr deref a NULL 'base'
pointer because the setting of base at the bottom of the loop is unconditional.

Alter the code to set "base = cur" after processing each key. That will
"ensure" that base doesn't get set to NULL if both "cpu" and "revision"
do no follow a "processor".

While a /proc/cpuinfo file that has a "processor" key but with neither
a "cpu" nor a "revision" doesn't seem feasible, the code is written as if
it could happen, so we have to account for it.
