unusedStructMember warnings from cppcheck are not reliable and
are causing a lot of false positives, suppress the checker
globally for now.

Add a way to exclude files from the scan, in this way we can skip
some findings from the report on those files that Xen doesn't own.
To do that, introduce the exclude-list.json file under docs/misra,
this file will be populated with relative path to the files/folder
to be excluded.
Introduce a new module, exclusion_file_list.py, to deal with the
exclusion list file and use the new module in cppcheck_analysis.py
to take a list of excluded paths to update the suppression list of
cppcheck.
Modified --suppress flag for cppcheck tool to remove
unmatchedSuppression findings for those external file that are
listed but for example not built for the current architecture.
Add documentation for the file.

Add parameter to skip the passed MISRA rules during the cppcheck
analysis, the rules are specified as a list of comma separated
rules with the MISRA number notation (e.g. 1.1,1.3,...).
Modify convert_misra_doc.py script to take an extra parameter
giving a list of MISRA rule to be skipped, comma separated.
While there, fix some typos in the help and print functions.
Modify settings.py and cppcheck_analysis.py to have a new
parameter (--cppcheck-skip-rules) used to specify a list of
MISRA rule to be skipped during the cppcheck analysis.

Sort alphabetically cppcheck report entries when producing the text
report, this will help comparing different reports and will group
together findings from the same file.
The sort operation is performed with two criteria, the first one is
sorting by misra rule, the second one is sorting by file.

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.
