vcpu: Expose more parameters for register intercept result hypercall

This especially concerns subleaf_specific and ecx. In cases like topology configuration that are passed through the leafs 0xb or 0x1f, multiple subleafs are involved and thus the hypercall arguments need to be prepared accordingly.

In addition to the exposed configuration parameters, some more inline documentation is added to improve the understanding on the hypercall configuration and arguments.

vcpu: Implement set_cpuid2 call

This is complled by the absent topology handling in MSHV. Passing the CPUID leafs with the topology is integrated into the common mechanism of setting and patching CPUID in Cloud Hypervisor. As a side effect - now all the other CPUID values will be passed to the hypervisor through the register intercept call.

mshv: Pass topology explicitly while constructing cpuid

Unlike KVM, there's no internal handling for topoolgy under MSHV. Thus, if no topology has been passed during the CH launch, use the boot CPUs count to construct the topology struct.

The console arg parsing functionality is pulled through a dedicated class. The license is MIT which seems compatible with the IR license.

The ir-test program code is moved under misc-utils subdirectory, where the arg parsing library is added as well. The current options have been migrated to the new class, some more options have been added for a better flexibility.

Especially there are two new options to pass BUILD_DIR and SRC_DIR, that would override the corresponding environment variables if supplied. Otherwise, the env variables will be used, thus maintaining the backward compatible behavior.

The help output is automatically generated by the arg parsing library:

$ ./ir-test --help
Usage: ir-test [options]

Execute IR tests

  --show-diff                Print failed test diff to stdout
  --no-color                 Disable output colorization
  --build-dir arg (=.)       Bulid dir path. When passed, overrides the BUILD_DIR environment variable
  --src-dir arg (=.)         Source dir path. When passed, overrides the SRC_DIR environment variable
  --test-dir arg (=./tests)  Test dir path. 
  --ir-exe arg               Path to the `ir` test app. 
  -h, --help                 Display help text and exit

Unknown options would make the program bail out:

 $ ./ir-test --no-such-opt
ERROR: unknown option '--no-such-opt'
Try 'ir-test --help' for more information.

While on this change, several exception handling arguments have been constified to comply better with the other parts of the code.

Fixes: #10

Abandoning this one for now. The change is too extensive and leads the focus away from the main dev subject. The present functionality is good enough to serve the project. Any further functionality is to be supplied in a minimalistic manner, as the need arises.

Thanks
