* Remove double encoding in MathML via Unicode MathML spaces
We used to have a complex mechanic for escaping strings, marking them as
`needsEscape = false`, and then not escaping those strings (for
combining strings in `\operatorname`). But this doesn't really work
with `render`ing directly to a node, as `document.createTextNode` can't
be stopped from escaping.
I've thus removed this mechanic, which required the following changes:
* Switch MathML "smart space" encoding to use Unicode instead of
`&LongNames;` (which weren't working with `render` for the same reason).
* Hack our HTML/MathML serializer to not use `String.trim`, which wrecks
havoc with emitted Unicode spaces.
Now `toText()` doesn't escape, so strings concatenate in unescaped form,
and `toHTML()` only does the necessary escaping. Thus fix#1782.

* Remove trim hack thanks to diffable-html@4.0.0
* Switch back to jest-serializer-html
* Update mathMLTree.js
* Fix \\ and \newline after operator
Fix#1790. `\\` and `\newline` render as a span with classes
`mspace` and `newline`. We need to check for `newline` when bringing
spaces into the same `base` group.
* Add tests and comment
* Remove redundant consumeSpaces()
- Spaces after command sequence are ignored in Lexer
- parseExpression consumes spaces in the math mode
* Add catcode to Lexer, move comment parsing back to Lexer
- Fix parsing a comment before a sup/subscript argument
- Fix parsing a comment before an expression
- Fix parsing a comment before or between \hline
- Fix parsing a comment in the macro definition
- Fix parsing a comment including a command sequence

* Add missing math delimiter. Fix alphabetic order.
* Add test.
* Add spaces between parenthesis and square brackets.
* Move unsupported command (undefined control sequence) error to parseSymbol
* Change parseGivenFunction and parseFunction to parse only function
* Move \begin handling to environment.js
* Remove ParsedFunc/Arg, move logics into parseGroup

* Minor fixes
* Remove previously resolved TODO
* Minor fixes
* Update flow typing
* Fix tag positioning to live within katex-html parent
`.tag` has `position: absolute`, but this positions it relative to the nearest
parent with a non-static `position` (see
https://developer.mozilla.org/en-US/docs/Web/CSS/Containing_block).
This PR makes `.katex-display > .katex > .katex-html` that parent.
