Reka Kovacs e453e60d08 [analyzer] Highlight c_str() call in DanglingInternalBufferChecker. 
Add a bug visitor to DanglingInternalBufferChecker that places a note
at the point where the dangling pointer was obtained. The visitor is
handed over to MallocChecker and attached to the report there.

Reka Kovacs 18775fc9b7 [analyzer] Add dangling internal buffer check. 
This check will mark raw pointers to C++ standard library container internal
buffers 'released' when the objects themselves are destroyed. Such information
can be used by MallocChecker to warn about use-after-free problems.

In this first version, 'std::basic_string's are supported.
