The distutils package is deprecated and scheduled to be removed in
Python 3.12. Use the sysconfig module instead.

Runners on https://circleci.com/ use a custom version of Python without
Debian-specific patches which added option --install-layout=deb. This
leads to the following error:
error: option --install-layout not recognized
Fix this by creating a new environment variable dedicated to detect
CircleCI platform.

- use multiple jobs
- define _FORTIFY_SOURCE=2 to enable checks on standard string handling
functions due to macro/intrinsic overloads or function attributes
- allow to override clang and scan-build binaries, i.e. for using
versioned ones
- set PYTHON_SETUP_ARGS accordingly on Debian
- enable common warning -Wextra
- print build result

Several static analyzers (clang's one, Facebook Infer, etc.) warn about
NULL pointer dereferences after a call to CU_ASSERT_PTR_NOT_NULL_FATAL()
in the test code written using CUnit framework. This is because this
CUnit macro is too complex for them to understand that the pointer
cannot be NULL: it is translated to a call to CU_assertImplementation()
with an argument as TRUE in order to mean that the call is fatal if the
asserted condition failed (cf.
http://cunit.sourceforge.net/doxdocs/group__Framework.html).
A possible solution could consist in replacing the
CU_ASSERT_..._FATAL() calls by assert() ones, as most static analyzers
know about assert(). Nevertheless this seems to go against CUnit's API.
An alternative solution consists in overriding CU_ASSERT_..._FATAL()
macros in order to expand to assert() after a call to the matching
CU_ASSERT_...() non-fatal macro. This appears to work fine and to remove
many false-positive warnings from various static analyzers.
As this substitution should only occur when using static analyzer, put
it under #ifdef __CHECKER__, which is the macro used by sparse when
analyzing the Linux kernel.

- Python 2.7 is planned to be the last of the 2.x releases
- It's generally advised to use Python 3
- Majority of python/ scripts are already switched python3
- Users with python 2 only can still use:
$ make PYTHON=/usr/bin/python ....

Using clang's static analyzer is as simple as running "scan-build make",
but in order to obtain clean and reproducible results, the build
environment has to be cleaned beforehand ("make clean distclean").
Moreover the project requires running "make install" before "make test"
in order to install the dependencies needed for the tests, and running
these tests with the newly-built libraries requires a specific
LD_LIBRARY_PATH. This new script takes care of setting up everything
which is needed.
