As agreed during the last MISRA C discussion, I am adding the following
MISRA C rules: 7.1, 7.3, 18.3.
I am also adding 13.1 that was "agreed pending an analysis on the amount
of violations". There are zero violations reported by cppcheck.

Add the new MISRA C rules agreed by the MISRA C working group to
docs/misra/rules.rst.
Add a comment for Rule 19.1 to explain that Eclair's findings are
"caution" reports, not violations.

Add Rule 5.1, with the additional note that the character limit for Xen
is 40 characters.
The max length identifiers found by ECLAIR are:
__mitigate_spectre_bhb_clear_insn_start
domain_pause_by_systemcontroller_nosync
Both of them are 40 characters long.
Explicitly mention that public headers might have longer identifiers.

Introduce a list of MISRA C rules that apply to the Xen hypervisor. The
list is in RST format.
Specify that rules deviations need to be documented. Introduce a
documentation tag for in-code comments to mark them as deviations. Also
mention that other documentation mechanisms are work-in-progress.
Add a mention of the new list to CODING_STYLE.
