Subject: [PATCH 06/18] DOC: update CONTRIBUTING regarding optional parts and
 message format

Make it clear that optional components must not break when disabled,
that openssl is the only officially supported library and its support
must not be broken, and that bug fixes must always be detailed.
(cherry picked from commit 9d84cd602f4adb3954209eb14c94eea9254d1b5b)

 Since most of these restrictions are just a matter of coding style, it is
 normally not a problem to comply.
 
+When modifying some optional subsystem (SSL, Lua, compression, device detection
+engines), please make sure the code continues to build (and to work) when these
+features are disabled. Similarly, when modifying the SSL stack, please always
+ensure that supported OpenSSL versions continue to build and to work, especially
+if you modify support for alternate libraries. Clean support for the legacy
+OpenSSL libraries is mandatory, support for its derivatives is a bonus and may
+occasionally break eventhough a great care is taken. In other words, if you
+provide a patch for OpenSSL you don't need to test its derivatives, but if you
+provide a patch for a derivative you also need to test with OpenSSL.

+   As a rule of thumb, your patch MUST NEVER be made only of a subject line,
    it *must* contain a description. Even one or two lines, or indicating
    whether a backport is desired or not. It turns out that single-line commits
    are so rare in the Git world that they require special manual (hence
    painful) handling when they are backported, and at least for this reason
    it's important to keep this in mind.
 
+   Each patch fixing a bug MUST be tagged with "BUG", a severity level, an
+   indication of the affected subsystem and a brief description of the nature
+   of the issue in the subject line, and a detailed analysis in the message
+   body. The explanation of the user-visible impact and the need for
+   backporting to stable branches or not are MANDATORY. Bug fixes with no
+   indication will simply be rejected as they are very likely to cause more

+   backported or can be reverted in case of regression.
