Some checkers may not only depend on language options but also analyzer options.
To make this possible this patch changes the parameter of the shouldRegister*
function to CheckerManager to be able to query the analyzer options when
deciding whether the checker should be registered.

Container operations such as `push_back()`, `pop_front()`
etc. increment and decrement the abstract begin and end
symbols of containers. This patch introduces note tags
to `ContainerModeling` to track these changes. This helps
the user to better identify the source of errors related
to containers and iterators.

Upon calling one of the functions `std::advance()`, `std::prev()` and
`std::next()` iterators could get out of their valid range which leads
to undefined behavior. If all these funcions are inlined together with
the functions they call internally (e.g. `__advance()` called by
`std::advance()` in some implementations) the error is detected by
`IteratorRangeChecker` but the bug location is inside the STL
implementation. Even worse, if the budget runs out and one of the calls
is not inlined the bug remains undetected. This patch fixes this
behavior: all the bugs are detected at the point of the STL function
invocation.

A monolithic checker class is hard to maintain. This patch splits it up
into a modeling part, the three checkers and a debug checker. The common
functions are moved into a library.
