commit 5696f07ad37bb3cf5250fe7c2e0a2471933fe041

    Reduce byte compiler warning
    
    * tex.el (): Move `(eval-when-compile (require 'dbus))' before
    `declare-function's of dbus related functions because otherwise they
    seem ineffective.
    Both NOERROR optional argument for `(require 'dbus)' and `(featurep
    'dbusbind)' test are removed deliberately because
    (1) Now all supported emacsen have dbus.el.
    (2) Even if emacs is built with configure option "--without-dbus", it
        doesn't cause error to load dbus.el just to get macro definition
        of `dbus-ignore-errors'.
    This way, it works fine even when
    (a) Emacs used for byte-compiling lacks D-Bus support.
    (b) Emacs at run time has D-Bus support.
    without relying on `TeX--if-macro-fboundp'.
    
    (): Remove `declare-function' for `dbus-ignore-errors' because it's
    now guaranteed that the macro is expanded away at byte compile time.
    (): Remove `defvar' for `dbus-debug' because `dbus.el' provides a
    suitable defvar.
