Federico Serafini 83e9e30510 automation/eclair: add a deviation for MISRA C:2012 Rule 8.6
Update ECLAIR configuration to take into account the search
procedure adopted by Unix linkers.
Update deviations.rst accordingly and tag Rule 8.6 as "clean".

Nicola Vetrini 26cdd09801 xen: address violations of Rule 11.9
The constant 0 is used instead of NULL in '__ACCESS_ONCE' as a
compile-time check to detect non-scalar types; its usage for this
purpose is deviated.

Furthermore, the 'typeof_field' macro is introduced as a general way
to access the type of a struct member without declaring a variable
of struct type. Both this macro and 'sizeof_field' are moved to
'xen/macros.h'.

No functional change intended.

Nicola Vetrini b739e2067b xen/include: add macro ISOLATE_LSB
The purpose of this macro is to encapsulate the well-known expression
'x & -x' that in 2's complement architectures on unsigned integers will
give a mask where only the least significant nonzero bit of 'x' is set,
or 0 if none are set.

A deviation for ECLAIR is also introduced.
