Introduce Float.ratio/1 and fix Float.{ceil/2, floor/2, round/2}
...
The previous implementations for ceil, floor and round were
not formalized and were likely prone to multiple roundings
as we performed multiplication and division by a power of
10 on the given float.
The new implementation correctly converts the float to an
exact integer representation and perform all operations using
arbitrary precision integers. The only float operation occurs
when converting the ratio back to a float.
The current implementation is more expensive due to its reliance
on big integers. Faster implementations are available in literature
where the latest one seems to be Errol:
https://cseweb.ucsd.edu/~lerner/papers/fp-printing-popl16.pdf
This change also introduces Float.ratio/1 which receives a
float and returns a pair of integers whose ratio is exactly equal
to the original float and with a positive denominator.
Closes #3400

Fix Dialyzer warnings on opaque protocol calls ( #5286 )
...
Prior to this change, calling a protocol function with an opaque type
would yield a warning, as Dialyzer concludes that the impl_for/1
function can't handle opaque arguments, since all clauses would
destructure their arguments in some way.
By adding a catch-all clause that does not destructure its argument,
Dialyzer no longer draws this conclusion, and the warnings go away.
As noted in the protocol.ex comment, this is technically a hack as it
relies on Dialyzer not being smart enough. However, I would not expect
it to break soon, if ever.
