* Added `linear<>` and `cache_last<>` options to singly linked lists. * Added `optimize_multikey<>` option to unordered container hooks. * Optimized unordered containers when `store_hash` option is used in the hook. * Implementation changed to be exception agnostic so that it can be used in environments without exceptions. * Added `container_from_iterator` function to tree-based containers. Interprocess: * Added anonymous shared memory for UNIX systems. * Fixed file lock compilation errors [SVN r44819]
