py/modmath: Convert log2 macro into a function.
...
So that a pointer to it can be passed as a pointer to math_generic_1. This
patch also makes the function work for single and double precision floating
point.

py/modmath: Add full checks for math domain errors.
...
This patch changes how most of the plain math functions are implemented:
there are now two generic math wrapper functions that take a pointer to a
math function (like sin, cos) and perform the necessary conversion to and
from MicroPython types. This helps to reduce code size. The generic
functions can also check for math domain errors in a generic way, by
testing if the result is NaN or infinity combined with finite inputs.
The result is that, with this patch, all math functions now have full
domain error checking (even gamma and lgamma) and code size has decreased
for most ports. Code size changes in bytes for those with the math module
are:
unix x64: -432
unix nanbox: -792
stm32: -88
esp8266: +12
Tests are also added to check domain errors are handled correctly.

py/modmath: Allow trunc/ceil/floor to return a big int if necessary.
...
Previous to this patch, if the result of the trunc/ceil/floor functions
overflowed a small int, or was inf or nan, then a garbage value was
returned. With this patch the correct big-int is returned if necessary,
and exceptions are raised for inf or nan.

py: Add MICROPY_FLOAT_CONST macro for defining float constants.

The implementation of these functions is very large (order 4k) and they

They are however enabled in stmhal and unix, since we have the room.
