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.
