First tried lts-14.7, but the version of cabal-install currently in debian
unstable (2.2.0.0) is not able to parse its cabal files.
Small fix for MonadFail changes.

Don't fully understand the need for the MonoLocalBinds language extension,
which was not needed before but now ghc complains if it's not included,
but I've tested it and it does work.
All the rest of the changes are straightforward AMP changes and dep
updates.
Removed fgl from stack.yaml because it seems that indirect dep no longer
needs to be specified for stack to build.
Added custom-setup stanza since stack now warns without one.

* gpg keyrings in /usr/share/debug-me/ will be checked
to see if a connecting person is a known developer of software
installed on the system, and so implicitly trusted already.
Software packages/projects can install keyrings to that location.
(Thanks to Sean Whitton for the idea.)
* make install will install /usr/share/debug-me/debug-me_developer.gpg,
which contains the key of Joey Hess. (stack and cabal installs don't
include this file because they typically don't install system-wide)
* debug-me.cabal: Added dependency on time.

Just in case, only allow printable characters in this, not control
characters.

When built with old websockets, compression is not supported. Client and
server will negotiate that so version skew between them is not a
problem.

Do include it in the data that gets signed, so it can be recovered
by trying each likely (recently seen) Activity as the prevMessage, and
checking the signature.
The UserState and DeveloperState already had the necessary state about
recently seen hashes, so this does not impact data use.
One tricky bit is that relayFromSocket needs to wait for the TMChan
to be empty before calling restorePrevActivityHash. Otherwise, the
hashes of items in the channel that have not been processed yet won't be
tried. The TMChan is not really being used as a channel since only 1
item can be in it. It could be converted to a TMVar, but closeTMChan is
used so I left it as a channel.
Note that the server does not restore hashes of messages that pass
through it; it's just a dumb relay.
Sending a single key press now only needs 94 bytes of data to be sent,
down from 169!
---
Also switched to SHA512, since hashes are no longer being sent over
the wire and so the larger size does not matter. SHA512 is slightly
faster and more secure.

This way it's not tied to details of the haskell binary library,
and implementations in other languages should be fairly simple to do.
The haskell protobuf library was used because it does not need extra
tooling or build steps. So I didn't write a .proto file, but one could
fairly easily be written by following ProtocolBuffers.hs and translating
it.
ProtocolBuffers.hs is *extremely* repetative and tedious code. Surely
there must be a way to not need to write all of that? Oh well, I wrote
it..
Sizes of serialized messages:
">>> debug-me session started": 121
sending a single key press: 169
This seems equally as efficient as the binary serialization was;
that was 165 bytes before elapsedTime was added.

Nice, was able to reuse all the protocol stuff from Role.Developer for
this.

Incomplete, but the client is able to connect and send messages which
get logged.
Split up debug-me.hs into Role/*
Switched from cereal to binary, since websockets operate on lazy
ByteStrings, and using cereal would involve a copy on every receive.

I tried both binary and cereal. For a ActivityMessage that takes 341
bytes in JSON and has a dataSize of 129, both used 165 bytes. Went with
cereal since lazy bytestrings are not needed, and I might want to use
https://hackage.haskell.org/package/safecopy later.
(Perhaps I should be using protocol buffers or something to make it
easier for non-haskell implementations? But that would complicate things
a lot.)

use now.

Prevent DOS of user side by limiting the size of the BackLog that
is maintained. This should not cause problems in even high latency
environments, and should prevent memory use > 16 mb.
The developer side does not keep much data, other than a list of the
Hashes of things it has recently sent, so is not susceptable to memory
DOS.

Most of the time, ByteStrings will be able to be encoded as utf8, so avoid
base64 when not needed.
Adjusted some of the types in order to generate more usual JSON. In particular,
removed StartActivity.
The JSON now looks like this (with the signature still not populated):
{"signature":{"v":""},"prevActivity":{"hashValue":{"v":"3b1abe614dd43bdb2d9a56777884e2d0f3bac9796e2d25c1ad52bb689c117286"},"hashMethod":"SHA256"},"activity":{"echoData":{"v":""},"enteredData":{"v":"l"}}}
203 bytes to send a single keystroke is not great when there's really
only 1+64(hash) bytes of unique data. So, may end up adding a wire
encoding on top of this. But, JSON is good to have for storage of the
proofs, etc.
Also, it does compress well. Two such JSON objects gzip -9 to 219
bytes, and three to 265 bytes. So, 37 bytes per keystroke. This is
*exactly* as efficient as gzip -9 of $c$hash formatted data.

Fairly straightforward, but did have to decide how to encode all the
ByteStrings, since they are not necessarily utf-8. Used base64.

I discovered the posix-pty library while looking for a way to forward
SIGWINCH to the slave pty. It's taken care of a lot of nasty pty
handling details, so let's use it!
Unfortunately, this broke control-d exiting debug-me, which used to work
great. I think that the problem is that readPty never returns B.empty,
even on control-d. Or perhaps, posix-pty is doing something to the pty
that prevents control-d getting through.
I kept all the withoutMode code; at least withoutMode EnableEcho
is still needed.

Still all in a single process with no serialization, but now there are
separate threads for the user and developer sides, and they communicate
Activity back and forth.
Signatures are not checked yet, but both user and developer check that
the other side is sending Activity that forms a valid hash chain with
previous Activity.
The echo simulation is included, but may be buggy. This seems to work
well enough with 0 latency at least.

Lots of terminal mode fun. Has a few warts still, but it works well
enough to be comfortable, and even vim works ok.
