1bdba953a5 Fix cursor left/right navigation in overset, underset, and stackrel
Before this commit, navigating with the cursor was visiting either
the nucleus or the script depending on the direction (left or right)
of the cursor movement. Now the 2.3.x behavior of always going through
the nucleus is restored (at least for overset and underset, as stackrel
seems to behave oddly also in 2.3.x).

9c3bbeefab Fix bug #11367
The overset, underset, and stackrel insets behave like the script
rather than the fraction inset.

097da3a943 Change cell numbers so that 0 is the main cell
This leads to code simplification in overset, root and underset.
Further simplification is possible.

89662a6852 Re-implement math markers logic.
The goal of this patch is to be able to properly remove the space
needed for markers in the case of insets that are inside macros and do
not need these markers. This was attempted at 9a9a6a8, but did not
work reliably.

To this end, the following simplifications are made:

* instead of drawing its own markers, each inset has a virtual method
  marker() which prescribes either NO_MARKER, MARKER (normal bottom
  marker) or MARKER2 (top and bottom marker). All explicit calls to
  (draw|metrics)Markers(|2) are removed.

* the space necessary for the markers is now counted in the
  before/above margins in the row structure. Therefore painting will
  not happen at (x + 1, y), but just (x,y).

* the methods drawDecoration are removed.

* the helper methods InsetMath::(draw|metrics)Markers(|2) are removed
  and replaced by a new function drawMarkers in MathRow.cpp.

Now the marker type is kept in the MathRow::Element object (and set to
NO_MARKER in not editable context) and the marker is accounted for in
MathRow::(metrics|draw).

Moreover, the extra pixel for the marker is taken on the before/After
space if possible. The marker will only require extra space when
before/after is 0.

See comment 168 of #8883 to understand what issues are fixed.

9a9a6a8c8f Skip drawing of markers in non-editable math data
There is no reason to reserve pixel space in macros replacement text,
which is not editable. This makes macros more compact and eases the
writing of lib/symbols.

* introduce new InsetMath::drawMarkers and friends that do nothing
  when nested inside a macro. This required to move macro_nesting
  inside MetricsBase, and to pass MetricsInfo & to metricsMarkers.

* keep track of nesting when drawing rows or macros.

361bd53bc3 Introduce the notion of math class
This done according to the TeXbook. This class replaces the individual
isMathXXX() methods. The mathClass() method (currently unused) is
provided for the following insets:

 * InsetMathChar (with a revised list of affected characters)
 * InsetMathSymbol: the class is given by the `extra' field
   Operators defined in lib/symbols (e.g. \log) are MC_OP
 * InsetMathFrac is MC_INNER (except nicefrac and units)
 * InsetDelimiters is MC_INNER
 * InsetStackrel is MC_REL
 * The class of InsetScript is the class of the last element of its
   nucleus (yes, it is a hack, but doing it right is more work).

Remove the explicit spacing that was done in the different insets. The spacing
will be reintroduced properly in a forthcoming commit.

e2bc7ffae3 RefChanger
RefChanger temporarily assigns a value to a non-const reference of any
kind. RefChanger provides a flexible and uniform generalisation of the various
scope guards previously derived from the old Changer class in MetricsInfo.h.

As before, a temporary assignment lasts as long as the Changer object lives. But
the new Changer is movable. In particular, contorsions are no longer needed to
change a private field. Special code can be moved into the appropriate classes,
and it is no longer necessary to create a new class for each specific use.

Syntax change:

   FontSetChanger dummy(mi.base, value);
-> Changer dummy = mi.base.changeFontSet(value);

New function for generating arbitrary Changers:

  Changer dummy = make_change(ref, val, condition);

Bugfix:

* Fix the display of \displaystyle{\substack{\frac{xyz}{}}} (missing style
  change).

56ece75ad9 Fix bug #8464: stackrel with subscript.
The fix is basically mechanical, the additional code for fraction like insets
with three arguments was stolen from \unitfrac. As any math package,
stackrel.sty needs a buffer parameter to switch it off.
I also added the two stackrel flavours to the toolbar.

* src/mathed/*.cpp:
	- Track mode (math or text) when outputting latex code and
	  properly wrap commands that are in the wrong mode with
	  either \ensuremath or \lyxmathsym.

* src/mathed/MathParser.cpp:
	- Parse \ensuremath and \lyxmathsym, such that exported latex
	  produces the same result when imported back.
	- Replace latex commands with corresponding unicode symbols.

* src/Encoding.cpp:
	- Implement Encodings::fromLaTeXCommand() for converting either
	  a single or a sequence of latex commands to unicode symbols.

237c132c1e * Inset:
- get rid of the cached Dimension. Text inset dimensions are saved in ParagraphMetrics and mathed maintain their own dimension where needed.
- width(), ascent(), descent(): deleted.
- dimension(): now needs a valid BufferView.
- metrics(): now void.

* BufferView::getCoveringInset(): simplify.

* ParagraphMetrics(): now cache inset dimensions.
