virttest: Call utils_net.update_mac_ip_address() in vm.create() when mac_changeable set to yes

Sometime we directly call vm.create() to create a VM. mac_changeable could not work
in this situation. As it only used in qemu test so move utils_net.update_mac_ip_address()
to vm.create() function.

If other test need support mac_changeable later, we can call  update_mac_ip_address
in its start() function.

virttest: Move nic_script under tap device branch in add_net

nic_script should be parameter for tap devices, so move it to
the right place. And now we can not control guest to use nic_script
or fds with cfg files as tapfds are automatic get by framework functions
only depends on the host env. So update the judgement as if we setup
nic_scritp, will let guest use script, otherwise will try to use fds.

virttest.utils_misc: Allow null source passed to umount.

Sometimes, we don't know what's source is, but mountpoint
can still be umounted, so allowing to pass null for umount.

autotest regression test: add a single VM (server only) mode

I've found that it's useful to check just the autotest installation steps
with a single VM with increased resources, mainly memory.

First 1G of memory is too little to do things like compiling the GWT client,
2G is OK, but 4G is preferrable. On most development machines (mine included),
starting two VMs with 2G or 4G is usually not a good idea.

To set this single VM (server only) mode, simply set the "vms" parameter to
a single (server) VM name.

Also, be a lot more generous about the installation timeout, as based on my
experience, things like downloading GWT and the git trees can take a long
time (YMMV).

shared.unattended: Disable the color display from console

The default bashrc for root in Ubuntu will enable color display
in the console. This caused unreadable characters for some
cmd output, like 'ls'. It will fail our cases as script can not
get the output we want. So disable it in preseed files for install.

Those subleaves need to stay stable on QEMU upgrades, too, so it is

qemu_cpu.cfg: Whitelist known broken alias bits on RHEL-6 qemu-kvm

Newer QEMU will make sure the alias bits are consistent, but there are

qemu_cpu.cfg: We don't need any image processing

The qemu_cpu test case doesn't use any disk image, so we don't need any
image processing when running the tests cases.

This should make the tests run much faster.
