Michael Albinus f8a9edce73 Fix some oddities, uncovered by Tramp tests 
* lisp/net/tramp-gvfs.el (tramp-gvfs-enabled): Prevent crash for
older Emacsen.

* lisp/net/tramp.el (tramp-process-running-p): Simplify.

* test/lisp/net/tramp-tests.el (tramp-test28-process-file): Adapt test.
(tramp-test33-environment-variables): Unset "INSIDE_EMACS" initially.

;;; Commentary:
;; Access functions for the GVFS daemon from Tramp. Tested with GVFS
;; 1.0 (Ubuntu 8.10, Gnome 2.24). It has been reported also to run
;; with GVFS 0.2.5 (Ubuntu 8.04, Gnome 2.22), but there is an
;; incompatibility with the mount_info structure, which has been
;; worked around.
;; It has also been tested with GVFS 1.6 (Ubuntu 10.04, Gnome 2.30),
;; where the default_location has been added to mount_info (see
;; <https://bugzilla.gnome.org/show_bug.cgi?id=561998>.
;; With GVFS 1.14 (Ubuntu 12.10, Gnome 3.6) the interfaces have been
;; changed, again. So we must introspect the D-Bus interfaces.
;; All actions to mount a remote location, and to retrieve mount
;; information, are performed by D-Bus messages. File operations
;; themselves are performed via the mounted filesystem in ~/.gvfs.
;; Consequently, GNU Emacs with enabled D-Bus bindings is a
;; precondition.
;; The GVFS D-Bus interface is said to be unstable. There were even
;; no introspection data before GVFS 1.14. The interface, as
;; discovered during development time, is given in respective
;; comments.
;; The user option `tramp-gvfs-methods' contains the list of supported
;; connection methods. Per default, these are "afp", "dav", "davs",
;; "gdrive", "media", "nextcloud" and "sftp".
;; "gdrive" and "nextcloud" connection methods require a respective
;; account in GNOME Online Accounts, with enabled "Files" service.
;; The "media" connection method is responsible for media devices,
;; like cell phones, tablets, cameras etc. The device must already be
;; connected via USB, before accessing it.
;; Other possible connection methods are "ftp", "http", "https" and
;; "smb". When one of these methods is added to the list, the remote
;; access for that method is performed via GVFS instead of the native
;; Tramp implementation. However, this is not recommended. These
;; methods are listed here for the benefit of file archives, see
;; tramp-archive.el.
;; GVFS offers even more connection methods. The complete list of
;; connection methods of the actual GVFS implementation can be
;; retrieved by:
;;
;; (message
;; "%s"
;; (mapcar
;; #'car
;; (dbus-call-method
;; :session tramp-gvfs-service-daemon tramp-gvfs-path-mounttracker
;; tramp-gvfs-interface-mounttracker "ListMountableInfo")))
;; See also /usr/share/gvfs/mounts
;; Note that all other connection methods are not tested, beside the
;; ones offered for customization in `tramp-gvfs-methods'. If you
;; request an additional connection method to be supported, please
;; drop me a note.
;; For hostname completion, information is retrieved from the zeroconf
;; daemon (for the "afp", "dav", "davs", and "sftp" methods). The
;; zeroconf daemon is pre-configured to discover services in the
;; "local" domain. If another domain shall be used for discovering
;; services, the user option `tramp-gvfs-zeroconf-domain' can be set
;; accordingly.
;; Restrictions:
;;
;; * Two shares of the same SMB server cannot be mounted in parallel.
;;; Code:
;; D-Bus support in the Emacs core can be disabled with configuration
;; option "--without-dbus". Declare used subroutines and variables.
