refactor(kernel): move printer and formatter objects to the kernel The printer and formatter objects are not trusted code. We moved them to the kernel to be able to provide them as an argument to the trace objects. Another motivation is to eliminate the kernel_exception_formatter hack. With the formatter in the kernel, we can implement the pretty printer for kernel exceptions as a virtual method.

refactor(frontends/lean/pp): replace dangerous frontend reference with a weak_ref to the environment Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2013-12-09 00:42:12 +00:00			`class environment;`
refactor(kernel/environment): add ro_environment The environment object is a "smart-pointer". Before this commit, the use of "const &" for environment objects was broken. For example, suppose we have a function f that should not modify the input environment. Before this commit, its signature would be void f(environment const & env) This is broken, f's implementation can easilty convert it to a read-write pointer by using the copy constructor. environment rw_env(env); Now, f can use rw_env to update env. To fix this issue, we now have ro_environment. It is a shared const pointer. We can convert an environment into a ro_environment, but not the other way around. ro_environment can also be seen as a form of documentation. For example, now it is clear that type_inferer is not updating the environment, since its constructor takes a ro_environment.
