Log:
[CONSRV]
Commit my work that I've done during my trip from Albi back to Paris (part 1/2):
- QuickEdit and InsertMode are input modes that are related to CONSRV terminal(s),
therefore remove them from CONDRV that needs to be agnostic about terminal specificities.
- Separate history helper functions from the line discipline functions to different
files.
