buffer_cache: Avoid passing references of shared pointers and misc style changes

Browse source 
Instead of using as template argument a shared pointer, use the
underlying type and manage shared pointers explicitly. This can make
removing shared pointers from the cache more easy.

While we are at it, make some misc style changes and general
improvements (like insert_or_assign instead of operator[] + operator=).
