Implement support for bare vars by `math` This change allows you to type `math x + 3` rather than `math $x + 3`. Another step to resolving issue #3157.

# Validate basic expressions
Default math scale to 6 This changes the behavior of builtin math to floating point by default. If the result of a computation is an integer, then it will be printed as an integer; otherwise it will be printed as a floating point decimal with up to 'scale' digits past the decimal point (default is 6, matching printf). Trailing zeros are trimmed. Values are rounded following printf semantics. Fixes #4478

add floating point output to `math` command This makes it easy for the user to request floating point output with the desired number of digits after the decimal point (not to be confused with significant digits). Note that this is just a thin wrapper so someone can say `math -s3 10 / 3` rather than `math "scale=3; 10 /3"`. Resolves #1643

Make builtin `math` the default implementation Remove our `math` function that wraps `bc`. Our math builtin is now good enough that it can be the default implementation. Another step in resolving #3157.

fix `math` regression The previous change to use `argparse` for parity with every other builtin and function introduced a regression. Invocations that start with a negative number can fail because the negative value looks like an invalid flag.

[math] Remove more bare variable support Prior to this fix, a "bare variable" in math like 'x + 1' would be looked up in the environment, i.e. equivalent to '$x + 1'. This appears to have been done for performance. However this breaks the orthogonality of fish; performance is not a sufficient justification to give math this level of built-in power, especially because the performance of math is not a bottleneck. The implementation is also ugly. Remove this feature so that variables must be prefixed with the dollar sign and undergo normal variable expansion. Reading 'git grep' output does not show any uses of this in fish functions or completions. Also added to changelog. Fixes #4393
