Make rustc-serialize, bignum, rational, complex into opt-out features
...
Making bignum optional allows skipping the rustc-serialize and rand
dependencies too, and it makes a big difference in num's build time.
With default (all) features, clean build time including dependencies: 27
seconds.
With no default features, clean build time including dependencies (none):
5 seconds.

If T is an unsigned integer type, these methods are guaranteed to

Vendor deprecated/unstable traits from std::num
...
This commit brings in a load of unstable and/or deprecated traits from
the `std::num` module. These traits provide for some degree of generic
programming over numeric types. They are not stable in `std` mostly
because we want more time to iterate on their design. Moving them to the
`num` crate allows existing code to keep using this functionality as we
do so.

pow: avoid unnecessary overflows
...
The code was performing an extra squaring of the base, which might
trigger an arithmetic overflow that doesn't matter to the result. Now
this squaring is only attempted when enough exp remains to need it.
A new doctest tries pow(6u8, 3), where an extra square would exceed 256.

Now, arithmetic binary operator traits take operands by value,
but non-copyable types such as `BigUint` should not always moved out when
applying operators.
This commit implements these operators not only for bare structs also
these references.
By-value implementations are forwarded to by-reference implementations
for now. In the future, by-value implementations may be replaced with
more efficient implementations (for example, the implementation that
reuses moved buffers.)
