    x86/pv: Prune include lists
    
    Several of these in particular haven't been pruned since the logic was all
    part of arch/x86/traps.c
    
    Some adjustments to header files are required to avoid compile errors:
     * emulate.h needs xen/sched.h because gdt_ldt_desc_ptr() uses v->vcpu_id.
     * mmconfig.h needs to forward declare acpi_table_header.
     * shadow.h and trace.h need to have uint*_t in scope before including the 
Xen
       public headers.  For shadow.h, reorder the includes.  For trace.h, 
include
       types.h
