Travis: Fix 'make checkcfg'

Start a major rewrite of CheckBufferOverrun. For now only the 'array index' and 'buffer overflow' checks are rewritten.
...
There are important TODOs still; for instance adding CTU support using our CTU infrastructure, add handling of pointers (maybe I'll use FwdAnalysis for this), add handling of multidimensional arrays, etc..

Handle concatenated string and char literals
...
This handles concatenated strings and characters from simplecpp.
Previously, L'c' would be preprocessed to the tokens "L" and "'c'".
cppcheck would then remove the "L" token and set "'c'" to be a wide
character literal. Now, it needs to remove the prefix instead.
When doing this, add handling of utf32 encoded literals (U) and UTF-8
encoded literals (u8).

checkuninitvar.cpp: Use argument direction "out" info from library cfg ( #1730 )

CheckUninitVar::isMemberVariableAssignment uses argument direction "out"
now also to check for assignment when the member variable is handed over
to a function by reference.
