This addresses an issue discovered by Inon Kaplan (PhD candidate in the
Hebrew University School of Computer Science and Engineering), Ron Even (BSc
graduate of Bar Ilan University) and Amit Klein (faculty member in the Hebrew
University School of Computer Science and Engineering). Details will be
provided in their paper, to be presented in a forthcoming academic conference.
The ID generation for IPv4 is changed to return a completely random number.

Since everything fits inside an int64, we avoid using crypto/rand.Int, which
can allocate and uses the much more complex big.Int.

Also:
- Add a secure RNG type to prevent mixing up with the default PRNG
- Give the PRNG the name `InsecureRNG` to make it more obvious to future
contributors that some RNGs are inappropriate in certain instances.
- Some tests were injecting fake RNGs and had to be relaxed: they relied on the
stack calling the RNG a specific number of times and in a specific order.
That order is now changed, and is too brittle to unit test.
- Remove the double package comment in pkg/rand. The linter complains.

This undocumented behavior manifests in Linux and some apps depend on it.

rand.Read() results in a syscall to the host on every call instead
we can wrap it with a bufio.Reader to buffer and reduce number of syscalls.
This is especially important for TCP where every newly created endpoint
reads random data to initialize the timestamp offsets for the endpoint.

* Rename syncutil to sync.
* Add aliases to sync types.
* Replace existing usage of standard library sync package.
This will make it easier to swap out synchronization primitives. For example,
this will allow us to use primitives from github.com/sasha-s/go-deadlock to
check for lock ordering violations.

This change also adds extensive testing to the p9 package via mocks. The sanity
checks and type checks are moved from the gofer into the core package, where
they can be more easily validated.

We have been unnecessarily creating too many savable types implicitly.
