With the old system `checkpatch.pl` gets one sole input that consists of
the commit message and commit diff of each commit between BASE_COMMIT
and HEAD. It also filters out changes in some files, which makes `git
format-patch` completely ignore that commit, even the commit message.
With the new system the commit message and commit diff are analyzed
separately. This means that, even if all the files modified by a commit
are filtered out, the commit message will still be analyzed.
Also, all commits are analyzed individually. This way it's easier to
know which commit caused the problem, and there are no warnings about
repeated "Signed-off-by" lines.

This patch updates the configuration file for the checkpatch.pl
script to check for the presence of a 'Signed-off-by' line in the
commit message. This is now required by TF contribution process.

At the moment, the top Makefile specifies the options to pass to the
checkpatch script in order to check the coding style. The checkpatch
script also supports reading its options from a configuration file
rather than from the command line.
This patch makes use of this feature and moves the checkpatch options
out of the Makefile. This simplifies the Makefile and makes things
clearer.
This patch also adds some more checkpatch options:
--showfile
--ignore FILE_PATH_CHANGES
--ignore AVOID_EXTERNS
--ignore NEW_TYPEDEFS
--ignore VOLATILE
The rationale behind each of these options has been documented
in the configuration file.
