Make log also accept a base. ( #1667 )
...
Make `log` in `racket/base` optionally accept a second argument.
The second argument is the log `base`. The docs also recommend
`fllogb` when precision is important.
* Error message when base is 1
* Added docs.
* Add tests.

doc clarifications on eqv?
...
Part of the clarification is duplicating information about numbers
and character in the documentation of `eqv?`. Since those two type
are the only special cases of `eqv?`, the duplication seems helpful
and managable.
