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.

logmsg Validate basic expressions
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

math 3 / 2
math 10/6
math -s0 10 / 6

math '10 % 6'
math -s0 '10 % 6'
math '23 % 7'
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 --scale=6 '5 / 3 * 0.3'
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.
