[XEN PATCH 09/13] xen/common: address violations of MISRA C:2012 Directive 4.10

[Simone Ballarin <simone.ballarin@xxxxxxxxxxx>]

Add inclusion guards to address violations of
MISRA C:2012 Directive 4.10 ("Precautions shall be taken in order
to prevent the contents of a header file being included more than
once").

Also C files, if included somewhere, need to comply with the guideline.

Mechanical change.
