Implement automatic terminal-local environment variables via `local-environment-variables'.
* lisp/env.el (setenv, getenv): Add optional terminal parameter. Update docs.
(setenv): Handle `local-environment-variables'.
(read-envvar-name): Also allow (and complete) local
environment variables on the current terminal.
* src/callproc.c: Include frame.h and termhooks.h, for terminal parameters.
(Qenvironment): New constant.
(Vlocal_environment_variables): New variable.
(syms_of_callproc): Register and initialize them.
(child_setup): Handle Vlocal_environment_variables.
(getenv_internal): Add terminal parameter. Handle
Vlocal_environment_variables.
(Fgetenv_internal): Add terminal parameter.
* src/termhooks.h (get_terminal_param): Declare.
* src/Makefile.in (callproc.o): Update dependencies.
* mac/makefile.MPW (callproc.c.x): Update dependencies.
* lisp/termdev.el (terminal-id): Make parameter optional.
(terminal-getenv, terminal-setenv, with-terminal-environment):
Disable functions.
* lisp/mule-cmds.el (set-locale-environment): Convert `terminal-getenv' calls
to `getenv'.
* lisp/rxvt.el (rxvt-set-background-mode): Ditto.
* lisp/x-win.el (x-initialize-window-system): Ditto.
* lisp/xterm.el (terminal-init-xterm): Ditto.
* lisp/server.el (server-process-filter): Fix reference to the 'display frame
parameter.
