Rename all instances of ECLAIR MISRA C:2012 service identifiers,
identified by the prefix MC3R1, to use the prefix MC3A2, which
refers to MISRA C:2012 Amendment 2 guidelines.
This update is motivated by the need to upgrade ECLAIR GitLab runners
that use the new naming scheme for MISRA C:2012 Amendment 2 guidelines.
Changes to the docs/misra directory are needed in order to keep
comment-based deviation up to date.

Implement the in-code suppression comment at the end of the line.
Now it is possible to add a Xen deviaiton comment with the syntax
described in the docs at the end of the line affected by the
violation, to deviate it.
Eclair natively supports it, so the translation for the tool will
be straighforward, but the other tool needs to translate an
occurrence of the tag into a suppressino comment at the end of the
previous line, this will have a corner case where the line number
1 of the file can't be deviated in this way for such tools.
Updated documentation.

Add Cppcheck analysis to the xen-analysis.py script using the
arguments --run-cppcheck.
Now cppcheck analysis will build Xen while the analysis is performed
on the source files, it will produce a text report and an additional
html output when the script is called with --cppcheck-html.
With this patch cppcheck will benefit of platform configuration files
that will help it to understand the target of the compilation and
improve the analysis. These are XML files placed in
xen/tools/cppcheck-plat/, describing to cppcheck the length of basic
types to help it in the analysis.
To do so:
- Update xen-analysis.py with the code to integrate cppcheck.
- add platform configuration files for cppcheck..
- add cppcheck-cc.sh script that is a wrapper for cppcheck and it's
used as Xen compiler, it will intercept all flags given from the
make build system and it will execute cppcheck on the compiled
file together with the file compilation.
- guarded hypercall-defs.c with CPPCHECK define because cppcheck
gets confused as the file does not contain c code.
- add false-positive-cppcheck.json file
- update documentation.
- update .gitignore

Add new script for coverity/eclair analysis tool that will enable
the procedure to suppress findings when these tool are used.
The procedure is documented in docs/misra/documenting-violations.rst
and the script is documented in docs/misra/xen-static-analysis.rst.
Add in docs/misra/ the files safe.json and
false-positive-{coverity,eclair}.json that are JSON files containing
the data structures for the justifications, they are used by the
analysis script to link the Xen tags to the proprietary tool comment.
Add docs/misra/documenting-violations.rst to explain how to add
justifications.
Add docs/misra/xen-static-analysis.rst to explain how to use the
script to analyse Xen.
Add analysis artifacts files to .gitignore.
