Replace Boris with PsySH

[damiankloip]

This is still a WIP, but thought I would post for now anyway.

In a nutshell, PsySH is much better, in every way. A couple of things off the top of my head now:

• Function, variable, and namespace autocompletion - MASSIVE!
• Ability to add custom commands in the shell itself
• Better support for exceptions/ability to get previous exceptions
• View user space code
• View docblocks
• Many more things.....

That's basically the examples I was going to put in here to show it off :) And yeah, not too shabby..

[damiankloip]

Also notice that it pages the output. Regular dump (default eval) just tells you the FQCN etc..

[weitzman]

Looks great. The exit command gives a fatal (see below). Any way to avoid that?

Can we backport this to 6.x?

[damiankloip]

@weitzman Yes, I noticed this too and was looking at this earlier. At first I thought this was an issue with PsySH, and we could fix it by adding our own Loop implementations. But IMO the real issue is that \Drupal\Core\DependencyInjection\Container::__sleep is calling trigger_error, otherwise it would be caught by PsySH and we would have no problem. https://www.drupal.org/node/2190643 added the trigger_error instead. Looks like DX reasons, and probably the exception being caught, and not having an indicative backtrace.

@jibran how about we get a working/merged version here first? :)

[jibran]

@damiankloip it's merged. Can we move to 6.x now?

[damiankloip]

Sure. Just open a new PR :) This is open source.

[damiankloip]

Also, why not 7.x?
