* Remove the UndoKind parameter in the general interface
* move recordUndoInset to Cursor
* remove one variant of Undo::recordUndo.
* get rid of Text::recUndo.
The old scheme was:
* multiple insertions are undone by groups of 20
* multiple deletions are undone in one big block
The new scheme is to stop merging undo elements after 2 seconds of elapsed time.
Moreover, the merging of undo elements stops when the cursor has moved. Potentially, this could allow to remove many of the finishUndo() calls.
Fixes bug #9204.
Rename recordUndoFullDocument to recordUndoFullBuffer.
Separate the notion of recording changes to paragraphs and recording changes in buffer parameters.
Audit every user of recordUndoFullDocument and replace it with either recordUndoBufferParams or recordUndoFullBuffer. Add comments to identify remaining work.

Fix thinko in Undo::endUndoGroup.
Do not reset undo groups in Undo::clean
The underlying problem remains: the various VC functions should not
always reload the buffer or at least should use the parameter
clearUndo=false.
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.
The undo range is extended to encompass all the paragraph after the end that
are a non-zero depth. The reason is that these paragraphs may see their depth
reduced if the last paragraph sees its depth reduced.
Note that there is a memory cost, since we store paragraphs than may not be
modified in practice. This may matter for some pathological files (people
putting all their document at depth 1 for a weird reason?)
I tried to be careful, but this can introduce new bugs. Please test.

* Undo.cpp:
- rename cur member of UndoElement to cur_before
- add new member cur_after, which is set by Undo::endUndoGroup
- create a new Undo::endUndoGroup variant that takes a Cursor as parameter. We cannot get rid of the old one because it is used for LFUN_COMMAND_SEQUENCE.
* Cursor.cpp:
- use endUndoGroup(Dociterator const &) for dispatch
- update Cursor::endUndoGroup to pass cursor.

- In GuiApplication::dispatch, do not call markDirty() for lfuns that are not ReadOnly
- In Undo::Private::recordUndo, call markDirty(). The indicator of dirtyness is now the existence of an undo element.
- In lyxfind, remove several markDirty calls that are not needed anymore.

- whitespace and typos in comments
- make sure that the Undo::recordUndoXXX functions all go through
Undo::Private::recordUndo

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.

* src/LyXAction.cpp: add ReadOnly flag to LFUN_UNDO and LFUN_REDO, since
we do not want the dispatch mechanism to mark buffer dirty after them.
* src/BufferView.cpp: handle "by hand" the activation of undo/redo
* src/Undo.cpp: add lyx_clean member to UndoElement and make sure to
maintain it with undo operations; add a new markDirty() member for UndoStack
* src/Buffer.cpp: when saving a document, mark the undo and redo stacks
elements as dirty.

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().

This patch encapsulates the needed call in Buffer::setBuffersForInsets(),
and calls it from Undo::Private::textUndoOrRedo(). As noted in the FIXME,
this is still a bit of a "hammer" and ought to be replaced with the sort of
more refined approach taken in r28709. But I don't at the moment see how to
do that. The place to do it, though, is in doTextUndoOrRed().

http://bugzilla.lyx.org/show_bug.cgi?id=5173
* Undo.cpp (beginUndoGroup, endUndoGroup): new methods.
(UndoElement): add group_id member
(UndoElementStack): when removing old undo entries, make sure to
remove whole groups.
(Undo::Private): add group_id and group_level (for nesting) members.
(doTextUndoOrRedo): new method. Apply _one_ UndoElement.
(textUndoOrRedo): call doTextUndoOrRedo on each element of the current
group.
(recordUndoFullDocument): put inside an undo group
* Cursor.cpp (beginUndoGroup, endUndoGroup): new methods.
* LyXFunc.cpp (dispatch): add calls to (begin|end)UndoGroup.
* lyxfind.cpp (replaceAll): use several recordUndo instead
of one recordUndoFullDocument.

A call to updateLabels() was necessary (and safer) in all cases.

I don't know at all what's up here with copied_ptr. Hadn't even heard of it until five minutes ago. ;-) You can cause this crash by opening a new document, opening Document>Settings and changing (say) the Bibliography settings, and then hitting "OK".
