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.

Fix trim() in lib/Preprocessor.cpp

Currently, if its argument is all spaces and tabs,
trim() returns it without actually trimming it.
Fix this by returning an empty string in this case.
Also, drop a useless test: if we did not return ""
then beg is not equal to std::string::npos, and in
that case, neither is end.
