Move ScopedReadMmap to ext/base

It's going to acquire another user in a future commit.

Also:
* Use nullptr in ptr_ to represent failure.
* Remove the virtual destructor: we don't need a vtable here.
* Make the class non copiable and non movable.
* Avoid logging in the implementation (logging is enhanced outside).
* Rename to ScopedMmap, in case we want to use iti for writing in the
  future.
* Instead of passing a filename to the constructor, create a function
  that accepts a filename and a length.
* Support mapping a whole file. It's going to be used in a future
  commit.
