Brings new bounds limiting and also prepares build system for the changes in the upstream. Namely shared_ptr header and namespace is now being detected by a build system rather than by hacks in the code. This commit includes some changes to auto-detection flags in SCons, presumably adding more consistency there. This is main changes which are suppoed to be reviewed here.
