Such helper is very similar to the existing xc_set_domain_cpu_policy
interface, but takes an opaque xc_cpu_policy_t instead of arrays of
CPUID leaves and MSRs.
No callers of the interface introduced in this patch.

With the introduction of xc_cpu_policy_get_{system,domain} and
xc_cpu_policy_serialise the current users of
xc_get_{system,domain}_cpu_policy can be switched to the new
interface.
Note that xc_get_{system,domain}_cpu_policy is removed from the public
interface and the functions are made static, since there are still
internal consumers in xg_cpuid_x86.c

Such helper allow converting a cpu policy into an array of
xen_cpuid_leaf_t and xen_msr_entry_t elements, which matches the
current interface of the CPUID/MSR functions. This is required in
order for the user to be able to parse the CPUID/MSR data.

Such helper is based on the existing functions to fetch a CPUID and
MSR policies, but uses the xc_cpu_policy_t type to return the data to
the caller.

Note some helper functions are introduced, those are split from
xc_cpu_policy_get_system because they will be used by other functions
also.

Introduce an opaque type that is used to store the CPUID and MSRs
policies of a domain. Such type uses the existing {cpuid,msr}_policy
structures to store the data, but doesn't expose the type to the users
of the xenguest library. There are also two arrays to allow for easier
serialization without requiring an allocation each time.
Introduce an allocation (init) and freeing function (destroy) to
manage the type.
Note the type is not yet used anywhere.

Preparatory change to introduce a new set of xc_cpu_policy_* functions
that will replace the current CPUID/MSR helpers.

Instead of each library having an own include directory move the
official headers to tools/include instead. This will drop the need to
link those headers to tools/include and there is no need any longer
to have library-specific include paths when building Xen.
While at it remove setting of the unused variable
PKG_CONFIG_CFLAGS_LOCAL in libs/*/Makefile.
