Addition by @problame: move getPipeCapacityHint() into platform-specific
code. This has the added benefit of not recognizing the envvar as an
envconst on platform that do not support resizing pipes. => won't show
up in (zrepl status --raw).Global.Envconst
fixes#424
cloes #449
A fairly common pattern when presented with JSON is to pipe it to `jq`.
This also allows one to `zrepl status --mode raw > log` and operate on
the JSON there.
closes#442
Primary goals:
- Scrollable output ( fixes#245 )
- Sending job signals from status view
- Filtering of output by filesystem
Implementation:
- original TUI framework: github.com/rivo/tview
- but: tview is quasi-unmaintained, didn't support some features
- => use fork https://gitlab.com/tslocum/cview
- however, don't buy into either too much to avoid lock-in
- instead: **port over the existing status UI drawing code
and adjust it to produce strings instead of directly
drawing into the termbox buffer**

From:
github.com/golang/protobuf v1.3.2
google.golang.org/grpc v1.17.0
To:
github.com/golang/protobuf v1.4.3
google.golang.org/grpc v1.35.0
google.golang.org/protobuf v1.25.0
About the two protobuf packages:
https://developers.google.com/protocol-buffers/docs/reference/go/faq
> Version v1.4.0 and higher of github.com/golang/protobuf wrap the new
implementation and permit programs to adopt the new API incrementally. For
example, the well-known types defined in github.com/golang/protobuf/ptypes are
simply aliases of those defined in the newer module. Thus,
google.golang.org/protobuf/types/known/emptypb and
github.com/golang/protobuf/ptypes/empty may be used interchangeably.
Notable Code Changes in zrepl:
- generate protobufs now contain a mutex so we can't copy them by value
anymore
- grpc.WithDialer is deprecated => use grpc.WithContextDialer instead
Go1.12 is now actually required by some of the dependencies.
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
