A simple INI configuration file for scan-build with options - aliases to scan-build command line arguments. This configuration file can be used to customize scan-build runs as it is done via command line. Options from this config are processed before any command line arguments so equivalent command line arguments passed to scan-build will overwrite values obtained from config. An order in which options are passed to scan-build is the same in which they occur in the config.
[[ https://llvm.org/bugs/show_bug.cgi?id=8203 | PR8203 ]] is related to the issue.
In the future I intend to use this config to also customize ccc/c++-analyzer script runs (to e.g pass special includes to Clang-analyzer, e.t.c).
Please review!

Currently looking through CMakeLists.txt in scan-build folder I do not exactly know where 'CommonStuff.pm' and 'scan-build.cfg' should be placed (BinFiles/LibexecFiles/ResourceFiles). Perhaps 'CommonStuff.pm' will go to the 'ResourceFiles' dir.
I am in favor of placing 'scan-build.cfg' to 'BinFiles' even bearing in mind hypothetical usage of this config by ccc/c++-analyzer scripts.

Tested the patch under Windows/Unix, any additional testing is appreciated!
