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.
This is a first cleanup step. More complex rules have to be
implemented on top of this.
Use proper spacing \thinmuskip, \medmuskip and \thickmuskip instead of
ad-hoc values.
Rename isRelOp to isMathRel and introduce isMathBin and isMathPunct
(for InsetMathChar and InsetMathSymbol). Update the categories of
characters in InsetMathChar according to LaTeX source (fontmath.ltx).
Set correctly the spacing around mathrel, mathbin and mathpunct
elements. Use \thinmuskip around MathDelim instead of a hardcoded 4.
This is related to bug #8883.
These were found by cppcheck:
Member variable 'x' is not initialized in the constructor.
The crash #9788 would not have happened if this had been done earlier.
stmaryrd.sty sets these symbols up as variable size math delimiters (i.e.
they may be used with \left and \right). Now LyX knows about that and offers
them in the delimiter dialog as well as single symbols.
Math manual loads and save correctly it seems but expect some instability period.

* 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.

- 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.
