From: Simone Ballarin <simone.ballarin@bugseng.com>

Amend 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").

Inclusion guards must appear at the beginning of the headers
(comments are permitted anywhere) and the #if directive cannot
be used for other checks.

Mechanical change.

Changes in v3:
- remove trailing underscores
- change inclusion guard name to adhere to the new standard
Changes in v2:
- drop changes in xen/include/xen/unaligned.h since this second
  series adds a comment-based deviation in a separate patch
- use #ifndef instead of #if !defined()

Provided the description of the scheme itself goes in first:

Given how exactly the guards look like is the main aspect here, I
question the retaining of earlier R-b with changes like what is said
here.
