[PATCH v2 2/5] xen/scripts: add cppcheck tool to the xen-analysis.py script



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

Changes in v2:
 - changes to commit message (Jan)
 - changes to the cppcheck-cc.sh script and on
   platform XML files, fixed version handling
   in cppcheck_analysis.py (Stefano)
 - Move revert of Makefile and xen/tools/merge_cppcheck_reports.py
   to the following patch, modified .gitignore to handle the
   presence of both Makefile invoked cppcheck and this new method
   (Stefano)

 Use cppcheck to analyse Xen
 ===========================
 
-Using cppcheck integration is very simple, it requires few steps:
-
- 1) Compile Xen
- 2) call the cppcheck make target to generate a report in xml format:
-    make CPPCHECK_MISRA=y cppcheck
- 3) call the cppcheck-html make target to generate a report in xml and html
-    format:
-    make CPPCHECK_MISRA=y cppcheck-html
-
-    In case the cppcheck binaries are not in the PATH, CPPCHECK and
-    CPPCHECK_HTMLREPORT variables can be overridden with the full path to the
-    binaries:
-
-    make -C xen \
-        CPPCHECK=/path/to/cppcheck \
-        CPPCHECK_HTMLREPORT=/path/to/cppcheck-htmlreport \
-        CPPCHECK_MISRA=y \
-        cppcheck-html
-
-The output is by default in a folder named cppcheck-htmlreport, but the name
-can be changed by passing it in the CPPCHECK_HTMLREPORT_OUTDIR variable.

+Analyse Xen with Cppcheck
+-------------------------
+
+Cppcheck tool is integrated in xen-analysis.py script, when using the script,
+the tool will be called on every source file compiled by the make build system.
+Here how to start the analysis with Cppcheck:
+
+ - xen-analysis.py --run-cppcheck [--cppcheck-misra] [--cppcheck-html] --
+   [optional make arguments]
+
+The command above tells the script to prepare the codebase and use Cppcheck 
tool
+for the analysis.
+The optional argument --cppcheck-misra activates the analysis also for MISRA
+compliance.
+The optional argument --cppcheck-html instruct cppcheck to produce an 
additional
+HTML report.
+
+When invoking the script for Cppcheck analysis, the followed procedure is
+similar to the one above for Coverity or Eclair, but it has some additional
+steps:
+
+ 1. This step is the same as step 1 for Coverity/Eclair.
+ 2. The cppcheck dependency are created, build directory for cppcheck analysis
+    and an header file containing internal compiler macro
+    (include/generated/compiler-def.h) are generated
+ 3. Xen compilation starts using every <additional make parameters> supplied
+    at the script invocation, but because cppcheck is not able to intercept the
+    compiled files and flags on compiler invocation, a script (cppcheck-cc.sh)
+    is passed as CC to the make system, it is a wrapper for the compiler that
+    will also execute cppcheck on every compiled file.
+ 4. After the compilation and analysis, the cppcheck report will be created
+    putting together all the cppcheck report fragments for every analysed file.
+    Cppcheck will produce a text fragment and an additional XML report fragment
+    if the script is configured to produce the HTML output.
+ 5. This step is the same as step 3 for Coverity/Eclair.
