[client] enable useful extra warnings

Browse Source 
-Wno-sign-compare is used to suppress warnings related to comparing signed
values with unsigned ones. It's too pedantic.

-Wunused-parameter is also too pedantic, especially since all parameters
have to be named in C.

Otherwise, -Wextra lets us catch bugs, such as x < 0 for unsigned x.

On gcc, we pass -Wimplicit-fallthrough=2 so it will recognize our fall
through comment.
