emacs: Support socket activation via systemd Add 'services.emacs.socketActivation.enable' for generating an 'emacs.socket' systemd unit. Emacs since version 26 has supported socket activation, whereby an external process manager such as systemd listens on a socket and passes it to the Emacs daemon when the manager launches it. This improves startup time of the user session and avoids launching the daemon when not needed, for example when launching the user session via SSH. This implementation hard-codes the socket path to the default for the version of 'programs.emacs.finalPackage', because systemd does not perform shell expansion in the socket unit's 'ListenStream' parameter and it seems like an advanced use-case to change the socket path. Shell expansion would be desirable as the socket path usually resides in directories such as $XDG_RUNTIME_DIR or $TMPDIR. Tests were added to verify behavior in the following cases: - Emacs service with socket activation disabled - Emacs 26 with socket activation enabled - Emacs 27 with socket activation enabled PR #1314 2020-06-08 21:01:17 +00:00			`[Install]`

services/emacs: Update systemd definitions, drop Emacs 26 support Emacs 27 added Type=notify support and updated the service definition to remove the use of `emacsclient' to kill the service. Emacs 28 changes the `StartupWMClass' in emacsclient.desktop to `Emacsd'. Update our emacs.service and emacsclient.desktop definitions to match upstream changes. When killing emacs.service, the socket is removed, and subsequently starting the service manually results in a service without a socket. Prevent this by adding `RefuseManualStart=true' to the service's Unit definition. Drop Emacs 26 support as it is no longer shipped in nixpkgs. Update the tests to verify the following configuration scenarios: - Emacs version: 27, 28 - Socket activation: disabled, enabled 2021-05-23 20:24:30 +00:00			`Description=Emacs text editor`
