Library: Enhance minsize configuration and allow simple values. (#1736) 
Some POSIX and Windows functions require buffers of at least some
specific size. This is now possible to configure via for example this
minsize configuration: `<minsize type="value" value="26"/>`.
The range for valid buffer size values is 1 to LLONG_MAX

Load std.cfg before all other libraries (#1740) 
- CLI: Save the libraries that should be loaded to a list and load them
after the std.cfg has been loaded.
- GUI: Load std.cfg (and windows.cfg / posix.cfg when applicable) before
setting other options and loading the other libraries.
In the project-file-dialog the std.cfg is searched first. If some
other library fails to load is is retried with first loading std.cfg.
- boost.cfg: Enable containers that depend on std containers.

729f57d8f1 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..

6a3dd9a185 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).
