81ba2298b2 video: cleanup usage of vram attribute and update documentation
The vram attribute was introduced to set the video memory but it is
usable only for few hypervisors excluding QEMU/KVM and the old XEN
driver. Only in case of QEMU the vram was used for QXL.

This patch updates the documentation to reflect current code in libvirt
and also changes the cases when we will set the default vram attribute.
It also fixes existing strange default value for VGA devices 9MB to 16MB
because the video ram should be rounded to power of two.

The change of default value could affect migrations but I found out that
QEMU always round the video ram to power of two internally so it's safe
to change the default value to the next closest power of two and also
silently correct every domain XML definition. And it's also safe because
we don't pass the value to QEMU.

ef01622607 qemu: parse -device virtio-balloon
There are no options to parse here other than the name of the device,
and all three possible device names have the same prefix
("virtio-balloon" with "-ccw", "-pci", or "-device" appended), so the
code is fairly simple. It has been implemented such that it will be
easier to add handling for other -device entries that aren't otherwise
recognized - just add another "else if (STRPREFIX(opts, ....)" clause.

qemuParseCommandLineString() previously would always add a <memballoon
model='virtio'/> to every result (the comments erroneously say that it
is adding a <memballoon model='none'/>) This has been changed to add
model='none', and 84 test case xml's updated accordingly (so that
qemuxml2argvtest won't fail).

Now that the memballoon device is properly parsed, we can safely add a
test for properly ignoring -nodefconfig and -nodefaults. Rather than
adding an entire new test case for this (and memballoon), we just
randomly pick the clock-utc test and modify it slightly to fulfill the
purpose.

There is no keyboard working on PPC64 and PS2 mouse is only for X86
when graphics are enabled.

Add a USB keyboard and USB mouse for PPC64 when graphics are enabled.

b39275954b conf: Remove the implicit PS2 devices for non-X86 platforms
PS2 devices only work on X86 platform, other platforms may need
USB devices instead. Athough it doesn't influence the QEMU command line,
it's not right to add PS2 mouse/keyboard for non-X86 platform.

bc18373391 conf: Add keyboard input device type
There is no keyboard support currently in libvirt.

For some platforms (PPC64 QEMU) this makes graphics unusable,
since the keyboard is not implicit and it can't be added via libvirt.

ec1c34498b virsh domxml-from-native to treat SCSI as the bus type for pseries by default
The bus type IDE being enum Zero, the bus type on pseries system appears as IDE for all the -hda/-cdrom and for disk drives with if="none" type. Pseries platform needs this to appear as SCSI instead of IDE. The ide being not supported, the explicit requests for ide devices will return an error.
