[XEN PATCH 0/8] xen: address MISRA C:2012 Rule 8.4

[Nicola Vetrini <nicola.vetrini@bugseng.com>]

Rule states the following:
"A compatible declaration shall be visible when an object or function with
external linkage is defined".

This series deals with violations concerning functions and variables used by C
code (thus not used only within asm). The resolution strategies are as follows:

1. make the functions/variables static
2. include the header that contains the compatible declaration, or add one in
   the header if that's not the case.

No functional change.

Additional notes:
- other cases, such as functions/variables used only in asm code will be possibly
  dealt with in future patches.
- functions in 'gcov_base.c' are deviated, since they are called only from code
  generated by gcc in a particular non-release build configuration;
- variables in 'xen/include/acpi/acglobal.h' are deviated temporarily, since
  it's uncertain whether modifying the include pattern to be compliant with the
	rule would introduce subtle bugs.
