40e2d5fcb6 Add Python bindings 
The bindings are implemented via python-cffi and cover all
current functionality of the library. They do not provide
a 1-to-1 mapping of the functionality, but a more "Pythonic"
API instead.

When new functionality is added to the libcpuid library
in the future, the changes must be manually added to the
bindings in order to appear in the Python interface.
However, if only a C enum is extended, the changes will
be automatically reflected in the Python interface.

6c87edab5a Remove CPU_ prefix from x86 cpu_feature_level_t enum options 
This makes the option names of cpu_feature_level_t consistent
and it also makes it easier to list options of the cpu_feature_t
enum just by their prefix (because it now doesn't collide with
the prefix of cpu_feature_level_t options).

Fix SEGFAULT in debugf() when using --quiet 
The `--quiet` option calls `cpuid_set_warn_function(NULL)`, but debugf() was not checking if _warn_fun is defined unlike warnf()

Fix a regression in cpuid_tool when ident_required=0 for arg 
In 2b8023f733, I had to update the behavior of cpuid_tool to loop over all data.cpu_types items.
I did not realize since this change, it was not entering the loop for args with ident_required=0, because data.num_cpu_types was always 0, so print_info() was never called for such args.

In other words, args like --rdmsr or --cpuid did nothing due to this regression. This commit fix this regression.

Fix scanf() format for 'logical_cpu' in cpuid_deserialize_raw_data_internal() 
logical_cpu is an uint16_t, so SCNu16 is the correct format. It was providing strange values with SCNi16, like with the Intel® Xeon® Platinum 8280 dump.

Provide raw for logical CPU 0 in cpuid_get_raw_data_core() even if set_cpu_affinity() is not supported 
On OpenBSD, set_cpu_affinity() is not supported, so cpuid_get_raw_data_core() always returns ERR_INVCNB.
This commit allows to provide raw data for at least one CPU core.

Improve set_cpu_affinity() on NetBSD 
By default, running libcpuid as regular user on NetBSD shows nothing: set_cpu_affinity() fails quietly so cpu_identify_all() is not able to get raw data.
This commit display a warning when an unallowed user try to set CPU affinity.
