[XEN PATCH][for-4.19 v2 0/1] address violations of MISRA C:2012 Rule 11.9

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

Rule 11.9 forbids the usage of '0' as a null pointer constant, therefore uses of
this pattern have been amended. One exception, recorded in deviations.rst, is in
__ACCESS_ONCE to do a scalar type check.

Changes in v2:
- dropped patch 2, as it has already been committed to [1]
- rebased against [2] to insert the deviation record in the newly created
  deviations.rst
