Hermès Bélusca-Maïto 01729482ae [CONSOLE.DLL] 
- Fix passing and retrieving gui terminal front-end information.
- Fix default (global) console parameters saving.

[CONSRV]
- PSEH2-protect calls to CreateRemoteThread when 1. calling console app. control handlers and 2. retrieving console settings from console.dll.
- Introduce a new way of locking consoles when being used, and store them in a list.
