py: Implement full behaviour of dict.update(), and dict().

Add keyword args to dict.update(), and ability to take a dictionary as
argument.

dict() class constructor can now use dict.update() directly.

This patch loses fast path for dict(other_dict), but is that really
needed?  Any anyway, this idiom will now re-hash the dictionary, so is
arguably more memory efficient.

Addresses issue #647.
py: Fix configuration of math module.
py: Allow tail call optimisation in mp_call_function_n_kw.

This saves 4 words of stack space per Python call.
py: Properly fix configuration of float and math module.

Simplify detection of quote characters in mp_str_print_quoted.

Once a double quote has been found, the subsequent discovery of a single quote
won't change behaviour at all, so don't bother looking for one.
