This provides a complete support for the semantics element. When the first child is a content MathML, an annotation can be selected and displayed. The selection algorithm is identical to Gecko's one. The recognized annotations are text (e.g. LaTeX), presentation MathML, SVG and HTML.

Tests: mathml/presentation/maction-dynamic.html

This adds a new MathMLSelectElement class to prepare the implementation
of the <maction> and <semantics> elements, for which only one "selected"
child is visible. We now simply display the first child of the
<semantics> element instead of hiding the annotations and this allows to
handle the use case of SVG-in-MathML as generated by Instiki when
bug 124128 is fixed ; Gecko's selection algorithm will be implemented
later (bug 100626). We now also rely on the @actiontype and @selection
attributes to select the visible <maction> child ; It remains to deal
with the user interaction (bug 85734).

MathML stretched operators by both modifying the width of the operator
and adding children to the operator node in the render tree.

Instead we make the operator width equal to the widest glyph possible that we use
to represent the operator.  Additionally instead of rendering stretchy glyphs via
stacked operator pieces in separate render tree nodes, keep only one node for the
glyph, and use a custom paint method to paint the stacked representation.

With this patch, rendering seems roughly equivalent on Mac and markedly better
on Linux.

This relies on the existing msub/msup/msubsup code to implement the mmultiscripts tag. This also improves dynamic addition/removal of children for these MathML elements and adds a specific style for invalid children, so that they render like an merror tag. Finally, this fixes a bad memory access in the Accessibility render object of msubsup.

Source/WebCore:

MathML sometimes creates and destroys renderers for descendants during layout (or even to calculate
preferred logical widths), e.g. for operator stretching. RenderBlock::finishDelayUpdateScrollInfo
must therefore leave gDelayedUpdateScrollInfoSet intact as it iterates over it, so
RenderBlock::willBeDestroyed can call gDelayedUpdateScrollInfoSet->remove(this) effectively if needed.
This also prevents duplicate entries from being added to gDelayedUpdateScrollInfoSet.

Test: mathml/mo-stretch-crash.html

* rendering/RenderBlock.cpp:
(WebCore::RenderBlock::startDelayUpdateScrollInfo):
    - Allow gDelayedUpdateScrollInfoSet to be non-null when gDelayUpdateScrollInfo is 0 during
      RenderBlock::finishDelayUpdateScrollInfo.
(WebCore::RenderBlock::finishDelayUpdateScrollInfo):
    - Remove blocks from gDelayedUpdateScrollInfoSet one at a time, waiting for each block until it is
      about to be updated.

Source/WebCore:

MathML addChild methods need to handle any anonymous renderers correctly. Actually, most MathML elements have a fixed
number of children, so conformant javascript won't be doing arbitrary addChild and removeChild calls. However, we don't
want any assertions to fail, and we do want addChild to work correctly when beforeChild == 0, to build up the original
renderer, and then replaceChild at least should work correctly after that. We therefore clean up these routines before
giving them to the chromium fuzzers.

It's best to build the anonymous wrappers just once initially if possible, so empty wrappers aren't left in the render
tree after later removeChild calls.

Test: mathml/presentation/dynamic.html added for mfrac and msqrt. There are already tests for dynamically changing
msub/sup elements, in mathml/presentation/m*-changed.xhtml.

* rendering/mathml/RenderMathMLFraction.cpp:
(WebCore::RenderMathMLFraction::addChild):
    - The two wrappers are built initially. Also, the old RenderMathMLBlock::addChild(row, beforeChild); doesn't really
      work because beforeChild is buried inside a wrapper. This new routine allows the numerator and denominator to be
      added initially, and then later replaced with replaceChild. It's not clear whether e.g. a plain removeChild of a
      numerator should move the remaining child from the denominator to the numerator or not, so we ignore that for now.
* rendering/mathml/RenderMathMLRoot.cpp:
(WebCore::RenderMathMLRoot::addChild):
    - A bit of bullet-proofing for the fuzzers.
* rendering/mathml/RenderMathMLSubSup.cpp:
(WebCore::RenderMathMLSubSup::addChild):
    - Like RenderMathMLFraction::addChild, we create the wrappers once initially, and then fill them dynamically.

Source/WebCore: 

For parts of stretched parentheses and brackets, mathml.css currently uses the Symbol font,
which on linux and Windows has greek letters at roman code points. To fix this, we switch
to the STIXSizeOneSym font when available. However, this can cause vertical gaps between
glyph parts, because of hard-coded constants in RenderMathMLOperator.cpp. We eliminate all
these constants. We also shift glyphs upward by 1px and truncate them to avoid the gaps.

Tested by existing tests, and one test added to LayoutTests/mathml/presentation/mo.xhtml.

    - Set font-family for mn, mi, etc.
