This commit does a bit more than fix selection, since it saves the full cursor state
in the undo stack. This means that undo now restores:
* the selection
* the current font
* transient mark (shall we keep this one?), logical position...
In order to do that, it introduces an intermediate class between Cursor and DotIterator: CursorData.
The new inheritance diagram is thus
DocIteraator -> CursorData -> Cursor
CursorData contains all the members of Cursor that define the current position, but not the stuff
related to current view of dispatch mechanism. It may make sense in the future to move members
between CursorData and Cursor and to move some member functions to CursorData.
Now UndoElement uses CursorData for cur_before and cur_after, but not for the cell. The undo API uses
also CursorData instead of DocIterator.
we will be cautious, of course). The problem was that we were issuing
the Buffer::changed() signal before we did updateBuffer(), and this
caused an inconsistency. The idea here is to defer issuing this signal
until we call processUpdateFlags(). We know we need a redraw if we've
deleted a whole paragraph.
This should work properly, so long as checkDepm is called from within
the dispatch mechanism. There may, however, be other paths, and I've
noted one explicitly with a FIXME in Text2.cpp. I've tested a few
different variations, however, and I haven't seen any problems. But if
we do run into problems, we can go ahead and do the update there that we
were previously doing in checkDepm itself.

THis is a consequence of the new AtPoint mechanism. In the old
world, recordUndoInset was called before INSET_MODIFY. I reintroduced
manual recordUndoInset calls in all places that matter. I suspect
that this issue should be revisited later.
Note that recordUndoInset can now take an optional parameter that tells
what inset is concerned. This is useful because the cursor can be
either just inside the inset or in front of it.

DispatchResult to store a flag that tells us whether we need a buffer
update or not.
So: If you find a missing one, go to an appropriate place in the
dispatch and call cur.forceBufferUpdate() or, if you don't have a cursor
but do have a DispatchResult, call dr.forceBufferUpdate().
There is one remaining call I could not move, in
TextMetrics::redoParagraph. But this looks like an emergency call when
the macro context has not been set. There are also a couple calls that
are connected with buffer creation that I commented out, since the same
call is done again almost immediately. But I'm not positive about those.
Now the nice thing would be to do the same for updateMacros().

here ran into insufferable problems: I.e., a Cursor IS-A DocIterator in
the code now, whether it was before or not.

This required to make Cursor::disp_ mutable.
Also, the server parts now pass a DispatchResult object to dispatch (which is
a good thing anyway).

Move the AtPoint handling into the Cursor dispatch machinery
Note that the call to Cursor::getStatus is in BufferView::getStatus, while
the call to Cursor::dispatch is still in LyXFunc::dispatch. This needs to be
fixed, but the code there is a bit fragile.

Make sure we jump to the next or previous change when we switch search direction. Without this patch, the same Change will be found and only the cursor is moved from the end (or begin) to the begin (or end) of the selection.

Specifically, moved the functions which actually move left or right from Text
into Cursor, and changed the semantics so that they now return whether or not
the cursor has moved. The functions in Text now use the new functions in Cursor.
This change is being made in preparation of the Word-level visual movement.

places, i.e.
- BufferView::setMouseCursor,
- BufferView::mouseEventDispatch
- LyXFunc::dispatch
Before it was called from several dispatch handlers in the middle of the
dispatch process. Because the cursor might get invalidated, this is
not a good idea. We had plenty of crashes and odd behaviours because
of this as nobody really understood those cases.
This fixes (at least) #2069 and #4163.

"The idea of the beforeDispX/Y_ variables in the Cursor is to hold the position
of the cursor on screen before the lyxfunc is dispatched. But to get this the
metrics must be valid. It's updated in Cursor::dispatch before the dispatch
loop.
After inserting/deleting stuff (like when deleting the selected text before
inserting the alpha) the metrics are invalid. But the handler for the alpha
calls Cursor::dispatch after the deletion and hence the crash with your second
patch.
Here is a patch fixing that:
The beforeDispatchXY variable do not belong into the Cursor::dispatch because
Cursor::dispatch is often called "manually" by many handlers to some followup
action. So this logic must go somewhere else where it is sure that is not
updated after the metrics got invalidated."
