Preprocessor directives for addons
...
This patch augments the XML dumps with a 'directivelist'
subnode which lists all raw preprocessor directives met
while reading the source code in each configuration.
Also, the addons/cppcheckdata.py file has been extended
to give easy access to the list of directives and to
provide Python support for the --template (or short -t)
option.
Finally, an new addon, addons/y2038/y2038.py, is created
to detect when a glibc symbol might be Y2038-sensitive,
based on whether and how _TIME_BITS and _USE_TIME_BITS64
are defined when meeting the symbol.

Make syntaxError suppressable ( fixes #5917 and #7076 )
...
syntaxErrors were not suppressable, because they were treated as
InternalErrors which were thrown and catched during the checking,
and normal suppression rules were not applied for those.
We fix this by calling the normal reportErr() function that does
suppression matching.
