  1. api: remove Send bound from Arbitrary/Testable traits 

    The Send bound is a relic from the past. Indeed, the docs for the
Arbitrary trait have been outdated for quite some time. quickcheck
stopped running each test in a separate thread once
`std::panic::catch_unwind` was stabilized many moons ago. With
`catch_unwind`, the `Send` bound is no longer necessary.

We do need to retain the `'static` bound though. Without that,
implementing shrink seems implausible.

  3. api: make arbitrary use full number range 

    This commit tweaks the Arbitrary impls of number types (integers,
floats) to use the full range with a small bias toward "problem" values.
This is a change from prior behavior that would use the `size` parameter
to control the range of integers.

In retrospect, using the `size` parameter this way was probably
misguided. Instead, it should only be used to control the sizes of data
structures instead of also constraining numeric ranges. By constraining
numeric ranges, we leave out a huge space of values that are never
tested.

  4. api: add Arbitrary impl for CString 

    We add a little sophistication here for whether the CString is
completely valid UTF-8 or whether it's just an arbitrary mix of bytes.
(Excluding NUL of course.)

  5. rand: remove rand as a public dependency 

    This removes the use of the rand_core crate as a public dependency. It
is now an implementation detail.

We achieve this primarily by turning the `Gen` trait into a concrete
type and fixing the fallout.

This does make it impossible for callers to use their own `Gen`
implementations, but it's unclear how often this was being used (if at
all). This does also limit the number of RNG utility routines that
callers have easy access to. However, it should be possible to use
rand's `SeedableRng::from_{rng,seed}` routines to get access to more
general RNGs.
