Subject: core: add options "setvar" and "delvar" in command /buffer, rename
 option "localvar" to "listvar"

The option "localvar" (introduced long time ago, in WeeChat 0.3.0) is still
recognized by WeeChat, to stay compatible with any extension/script calling
it (or referencing it in the documentation).

It is deprecated and will be removed in a future release.
