The GNULIB physmem module already provides support for
the FreeBSD platform, so there's no reason to re-implement
FreeBSD portability code in libvirt. If there are bugs in
the GNULIB code, we should fix GNULIB rather than workaround
it in libvirt.

The nodeGetInfo() method currently has its own code for getting
memory size in KB, that basically just re-invents what nodeGetMemory
already does. Remove it and just call nodeGetMemory, converting its
result from bytes to KB, allowing removal of more platform specific
conditional code.

Nearly all the methods in the nodeinfo file are given a
'const char *sysfs_prefix' parameter to override the
default sysfs path (/sys/devices/system). Every single
caller passes in NULL for this, except one use in the
unit tests. Furthermore this parameter is totally
Linux-specific, when the APIs are intended to be cross
platform portable.

This removes the sysfs_prefix parameter and instead gives
a new method linuxNodeInfoSetSysFSSystemPath for use by
the test suite.

For two of the methods this hardcodes use of the constant
SYSFS_SYSTEM_PATH, since the test suite does not need to
override the path for thos methods.

If you want to set block device I/O tuning values that end with '_max'
and there is nothing else set, libvirt emits an error.  In particular:

  error: internal error: Unexpected error

That's an unknown error.  That is because *_max values depend on their
respective non-_max values.  QEMU even says that in the error message
sent as a response to the monitor command:

  "error": {"class": "GenericError", "desc": "bps_max/iops_max require
  corresponding bps/iops values"}

the problem was that we didn't know that and there was no check for it.
Adding such check makes sure that there will be less confused users.

This new listen type is currently supported only by spice graphics.
It's introduced to make it easier and clearer specify to not listen
anywhere in order to start a guest with OpenGL support.

The old way to do this was set spice graphics autoport='no' and don't
specify any ports.  The new way is to use <listen type='none'/>.  In
order to be able to migrate to old libvirt the migratable XML will be
generated without the listen element and with autoport='no'.  Also the
old configuration will be automatically converted to the this listen
type.

Add a new capability to detect support of unix sockets for spice
graphics.
Signed-off-by: NPavel Hrdina <phrdina@redhat.com>

VNC graphics already supports sockets but only via 'socket' attribute.
This patch coverts that attribute into listen type 'socket'.

For backward compatibility we need to handle listen type 'socket' and 'socket'
attribute properly to support old XMLs and new XMLs.  If both are provided they
have to match, if only one of them is provided we need to be able to parse that
configuration too.

To not break migration back to old libvirt if the socket is provided by user we
need to generate migratable XML without the listen element and use only 'socket'
attribute.

This moves the socket generation if "vnc_auto_unix_socket" is set.

It also fixes a bug with this config option that we should auto-generate
socket path only if listen type is address and there is no address
specified.
Signed-off-by: NPavel Hrdina <phrdina@redhat.com>

Even though it's auto-generated it's based on qemu.conf option and listen type
address already uses "fromConfig" to carry this information.  Following commits
will convert the socket to listen element so this rename is required because
there will be also an option to get socket auto-generated independently on the
qemu.conf option.

Since commit 71408079, qemu agent
channel cannot be plugged in because we won't generate its path

Until now, the only hot thing in this test was the name.  That's because
we set the id to '-1' before every test.  With this change, we test the
hotplug on live domains as the name suggests and as it should be.
