435b5b7ff9 Unify code that validates identifiers in Kakoune 
Session/Client/User modes names are now requiered to be "identifiers"
they must be in [a-zA-Z0-9_-]. Option names are the same except they
do not allow '-' as they need to be made available through the env vars
and '-' is not supported there.

Fixes #1946

db7b43acd5 Restore client name after converting to client 
When Kakoune forked the sever to background, the newly converted
to client process (the original client/server process) was not
preserving its previous client name.

aa82a90c39 Remote: stricter validation of the session names 
Creating a session will not accept any slashes in the session path,
connecting to an existing session will accept at most one slash to
allow for specifying the session of a different user.

event mode.

4fc20b8d7d Rework client quitting and handling of remote errors 
Client quitting no longer immediately unwinds, client is just pushed
for deletion until we get back to the main loop, similarly to what
happens for buffer and window deletion.
