A bunch of function definitions used empty parentheses instead of (void) syntax, yielding the following warning when building with clang on macOS:
warning: a function declaration without a prototype is deprecated in all versions of C [-Wstrict-prototypes]
In addition to fixing these function headers, it also fixes what appears to be a typo causing a variable to be unused after initialisation.
warning: variable 'entry_ctls' set but not used [-Wunused-but-set-variable]

When CPUArchState* is available (here CPUX86State*), we can
use the fast env_archcpu() macro to get ArchCPU* (here X86CPU*).
The QOM cast X86_CPU() macro will be slower when building with
--enable-qom-cast-debug.
Pass CPUX86State* as argument to simulate_rdmsr / simulate_wrmsr
instead of a CPUState* to avoid an extra cast.

We want all accelerators to share the same opaque pointer in
CPUState.
Rename the 'hvf_vcpu_state' structure as 'AccelCPUState'.
Use the generic 'accel' field of CPUState instead of 'hvf'.
Replace g_malloc0() by g_new0() for readability.
