Introduce a --force option to xen-ucode, in order to bypass certain checks
when applying microcode.
Update libxc's xc_microcode_update() to take an extra parameter, and to use
the new XENPF_microcode_update2 hypercall instead.

Right now, Xen returns -ENOENT for both "the provided blob isn't correct for
this CPU", and "the blob isn't newer than what's loaded".
This in turn causes xen-ucode to exit with an error, when "nothing to do" is
more commonly a success condition.
Handle EEXIST specially and exit cleanly.

Add an option to xen-ucode tool to print the currently loaded ucode
revision and also print it during usage info. Print CPU signature and
platform flags as well. The raw data comes from XENPF_get_cpu_version
and XENPF_get_ucode_revision platform ops.
Example output:
Intel: CPU signature 06-55-04 (raw 0x00050654) pf 0x1 revision 0x02006e05
AMD: CPU signature 19-01-01 (raw 0x00a00f11) revision 0x0a0011ce

Otherwise it's difficult to know if operation failed inside the automation.
While at it, also switch to returning 1 and 2 instead of errno to avoid
incompatibilies between errno and special exit code numbers.
