We should hide the empty narrow message message whenever the narrow is
not empty, but we should only select a message if non are currently
selected.

Now that we no longer use tables for our message list, we can
more logically group messages together.

This experiment has been disabled for everyone for a while: if we
bring something like this back, it is not likely to be exactly the same,
and will be different enough to require a different implementation.
As it is, the summarization code was making a few code paths (rendering
especially) more complex, and is worth removing for simplicity's sake.

Leo and I were looking over this code and I couldn't remember what it
was doing. So after I re-derived its purpose, we figured that an
explanatory comment was in order.

Summary blocks can contain hundreds of messages. When the rendering window
code didn't take this into account, it would lead to all kinds of
unpleasant behavior when you scroll.
Trac #1888
Unfortunately, this replaces a subtraction with a function that iterates
through all the messages.

When we call rerender() on MessageList, it is usually because
something big has happened, so it's reasonable that the pointer
may now be invalid. As an example, the old pointed-to message
may been removed from the home view. We have always just
moved the pointer under the hood, but now we do it in a way
that doesn't generate spurious blueslip errors.
(imported from commit d399a101f36b744a423ea7da80dda8352440c6c9)
This fixes a blueslip error where we were trying to add the same
message into a MessageList twice. Muting complicates our duplicate
detection, because empty() can return true even when we already
are storing messages that just aren't shown (because of muting).
The name empty() should probably be fixed in light of muting,
but filtering with self.get() is not really a problem here.
(imported from commit 83b0890471c9a0aa21996f3d0d3be4a238f23e65)
With the muting/hiding features, it has become the case that
this._hash can have entries that don't map to actually visible
rows, so this.get() can return true on an id that shouldn't
actually be selected, causing downstream code to explode. Now
we call this.closest_id() regardless of whether the hash is
populated, to be safe, but then we still call blueslip.error
if the pointer moved.
