  machine: Add a valid_cpu_types property

This patch add a MachineClass element that can be set in the machine C
code to specify a list of supported CPU types. If the supported CPU
types are specified the user enter CPU (by -cpu at runtime) is checked
against the supported types and QEMU exits if they aren't supported.

Both -nodefconfig and -no-user-config options do the same thing

  qemu-options: Deprecate -nodefconfig

Since 2012 (commit ba6212d8 "Eliminate cpus-x86_64.conf file") we
have no default config files that would be disabled using
-nodefconfig.  Update documentation and document -nodefconfig as
deprecated.

  config: qemu_config_parse() return number of config groups

Change qemu_config_parse() to return the number of config groups
in success and -EINVAL on error. This will allow callers of
qemu_config_parse() to check if something was really loaded from
the config file.

All existing callers of qemu_config_parse() and
qemu_read_config_file() only check if the return value was
negative, so the change shouldn't affect them.

Signed-off-by: Eduardo Habkost <address@hidden>

---Steps to Reproduce---

When passed a negative number to 'maxcpus' parameter, Qemu aborts
with a core dump.

Run the following command with maxcpus argument as negative number

ppc64-softmmu/qemu-system-ppc64 --nographic -vga none -machine
pseries,accel=kvm,kvm-type=HV -m size=200g -device virtio-blk-pci,
drive=rootdisk -drive file=/home/images/pegas-1.0-ppc64le.qcow2,

user -redir tcp:2000::22 -device nec-usb-xhci -smp 8,cores=1,
threads=1,maxcpus=-12
