Unless we're using the global source for math/rand, (*rand.Rand).Read
should not be called concurrently. We seed the rng in daemon.Run to
avoid ambiguity or hiding global side effects inside packages.

- `timeoutconn` handles state, yet calls to Read/Write make a copy of
that state (non-pointer receiver) so any outbound calls will not have
the state updated
- Even without the copy issue, the renew methods can in edge cases set a
new deadline _after_ DisableTimeouts have been called, consider the
following racy behavior:
1. `renewReadDeadline` is called, checks `renewDeadlinesDisabled`
(not disabled)
2. `DisableTimeouts` is called, sets `renewDeadlinesDisabled`
3. `DisableTimeouts` invokes `c.SetDeadline`
4. `renewReadDeadline` invokes `c.SetReadDeadline`
To fix the above, the `Conn` receiver was made to be a pointer
everywhere and access to renewDeadlinesDisabled is now guarded
by an RWMutex instead of using atomics.

Before this change, the step correlation code returned early in several cases:
- did not set f.planning.done in the cases where it was a no-op
- did not set f.planning.err in the cases where correlation did not
succeed

package is now at 95% code coverage and the additional tests codify
all behavior specified in the docs
There is a slight change in behavior:
Intervals are now [duration) instead of (duration].
If the leftmost interval is not keep=all, the most recently created
snapshot will be destroyed if there are other snapshots within
that first interval.
Since we recommend keep=all all over the docs, and zrepl 0.3
will put holds on that snapshot if it is being replicated,
I feel like this is an acceptable change in behavior.
