503c7c1688 When inserting math inset, put cursor selection in the correct cell
The original use case for this bug is entering an overset inset when
there is a selection. The expected result was to have the selection
pasted in main text, but the result was to have it in the cell.

Insets already have idxFirst() that is able to set cursor to the
"entry" cell of an inset. This patch introduces firstIdx(), which is
the index of this cell and uses it in idxFirst() (idem for
lastIdx/idxLast).

As a consequence, several instances of idxFirst/idxLast can be removed.

Now for the real fix: the two places where the cell in which selection
is inserted seem to be:
* Cursor::macroModeClose
* Cursor::handleNest

These two methods are changed to insert material in the entry cell
instead of cell 0.

idxFirst/Last methods are added to InsetMathRoot and InsetMathStackrel
so that the natural entry point is the nucleus of those insets.

Finallly, a typo is fixed in InsetMathNest::edit() where enter_front
computation was incorrect.

e30f3d76d2 Bulk cleanup/fix incorrect annotation at the end of namespaces.
This commit does a bulk fix of incorrect annotations (comments) at the
end of namespaces.

The commit was generated by initially running clang-format, and then
from the diff of the result extracting the hunks corresponding to
fixes of namespace comments. The changes being applied and all the
results have been manually reviewed. The source code successfully
builds on macOS.

Further details on the steps below, in case they're of interest to
someone else in the future.

1. Checkout a fresh and up to date version of src/

    git pull && git checkout -- src && git status src

2. Ensure there's a suitable .clang-format in place, i.e. with options
   to fix the comment at the end of namespaces, including:

    FixNamespaceComments:                           true
    SpacesBeforeTrailingComments:                   1

and that clang-format is >= 5.0.0, by doing e.g.:

    clang-format -dump-config | grep Comments:
    clang-format --version

3. Apply clang-format to the source:

    clang-format -i $(find src -name "*.cpp" -or -name "*.h")

4. Create and filter out hunks related to fixing the namespace

    git diff -U0 src > tmp.patch
    grepdiff '^} // namespace' --output-matching=hunk tmp.patch  > fix_namespace.patch

5. Filter out hunks corresponding to simple fixes into to a separate patch:

    pcregrep -M -e '^diff[^\n]+\nindex[^\n]+\n--- [^\n]+\n\+\+\+ [^\n]+\n'  \
        -e '^@@ -[0-9]+ \+[0-9]+ @@[^\n]*\n-\}[^\n]*\n\+\}[^\n]*\n'         \
        fix_namespace.patch > fix_namespace_simple.patch

6. Manually review the simple patch and then apply it, after first
   restoring the source.

    git checkout -- src
    patch -p1 < fix_namespace_simple.path

7. Manually review the (simple) changes and then stage the changes

    git diff src
    git add src

8. Again apply clang-format and filter out hunks related to any
   remaining fixes to the namespace, this time filter with more
   context. There will be fewer hunks as all the simple cases have
   already been handled:

    clang-format -i $(find src -name "*.cpp" -or -name "*.h")
    git diff src > tmp.patch
    grepdiff '^} // namespace' --output-matching=hunk tmp.patch  > fix_namespace2.patch

9. Manually review/edit the resulting patch file to remove hunks for files
   which need to be dealt with manually, noting the file names and
   line numbers. Then restore files to as before applying clang-format
   and apply the patch:

    git checkout src
    patch -p1 < fix_namespace2.patch

10. Manually fix the files noted in the previous step. Stage files,
    review changes and commit.

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.

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).

efaae780db Fix regression of 5261ae6a2
Somehow I overlooked that \sideset also supports nonscript arguments for
left and right. This is now fixed, although I do not like the toolbar names.
If somebody knows something better, please improve.

5261ae6a29 Fix bug #1424: Native \sideset inset
The toolbar image is the one Uwe attached to the bug report. Note that
\sideset works only for operators like \sum in the nucleus. LyX allows
any content, so you might get a LaTeX error. I don't know how to prevent
wrong content in the nucleus.
