Ethan Atkins bb8b9a1c99 Fix switching between raw and canonical input ... There were a number of issues with swithcing between raw and canonical issues that affected both the server and the thin client. These were reported in #5863 and #5856. In both cases, there were issues with reading input or having the input be displayed. Debugging those issues revealed a number of issues with how we were using the jline 3 system terminal and the hybrid interaction with the jline 2 terminal. This commit eliminates all of our internal jline 2 usage. The only remaining jline 2 usage is that we create and override the global terminal for the scala console for scala versions < 2.13. By moving away from jline 2, I was also able to fix #5828, which reported that the home, end and delete keys were not working. One of the big issues that this commit addresses is that the NetworkClient was always performing blocking reads on System.in. This was problematic because it turns out that you can't switch between raw and canonical modes when there is a read present. To fix this, the server now sends a message to the client when it wants to read bytes and only then does the client create a background thread to read a single byte. I also figured out how to set the terminal type properly for the thin client on windows where we had been manually setting the capabilities to ansi, which only worked for some keys. This fix required switching to the WindowsInputStream that I introduced in a prior commit. Before we were using the jline 2 wrapped input stream which was converting some system events, like home and end, to the wrong escape sequence mappings. The remainder of the commit is mostly just converting from jline 2 apis to jline 3 apis. I verified that tab completions, the scala console, the ammonite console and a run task that read from System.in all work with both the server and the thin client on mac, linux and windows after these changes.
