[XEN PATCH v5 00/17] xen: address violation of MISRA C:2012 Directive 4.10



The Xen sources contain violations of MISRA C:2012 Directive 4.10 whose 
headline states:
"Precautions shall be taken in order to prevent the contents of a header file
being included more than once".

Following V2, V3 and V4, here are all the rules that have been applied:
- private headers -> <dir>__<filename>_H
- asm-generic headers -> ASM_GENERIC__<filename>_H
- arch/<architecture>/include/asm/<subdir>/<filename>.h -> 
ASM__<architecture>__<subdir>__<filename>_H
- include/xen -> XEN__<filename>_H

https://lists.xenproject.org/archives/html/xen-devel/2023-10/msg02073.html

Furthermore, the violations arising from the autogenerated header files
include/xen/compile.h and xen/hypercall-defs.h are addressed.

Changes in v5:
edit inclusion guard naming conventions, according to feedback received
edit inclusion guards in header files reflecting the naming convention
fix some rebasing mistakes left in the previous version

Changes in v4:
add/amend inclusion guards to address violations of the Directive and the new 
naming convention.
drop teh XEN_ prefix when needed, according to the feedback received.
add inclusion guard naming convention section in CODING_STYLE

Changes in v3:
Add/amend inclusion guards to address violations of the Directive and the new 
naming convention.
Remove trailing underscores.
Modify creation rule for asm-offsets.h to conform to the new standard and to 
not generate conflicting
guards between architectures (which is a violation of the Directive).
