Clean up D-Bus documentation (bug#41744)

* doc/lispref/errors.texi (Standard Errors): The error symbol
dbus-error is defined even when Emacs is built without D-Bus.

* doc/misc/dbus.texi (Bus Names, Introspection)
(Nodes and Interfaces, Methods and Signal)
(Properties and Annotations, Arguments and Signatures)
(Synchronous Methods, Receiving Method Calls, Signals)
(Alternative Buses, Errors and Events): Clarify wording.  Fix
indentation of and simplify examples where possible.  Improve
Texinfo markup and cross-referencing where possible.
(Type Conversion): Ditto.  Remove mentions of Emacs' fixnum range
now that we have bignums.

* lisp/net/dbus.el (dbus-return-values-table)
(dbus-call-method-asynchronously, dbus-send-signal)
(dbus-register-signal, dbus-register-method)
(dbus-string-to-byte-array, dbus-byte-array-to-string)

has established to the BUS under the same unique name (see
`dbus-get-unique-name'). It depends on the libraries Emacs is
linked with, and on the environment Emacs is running. For
example, if Emacs is linked with the GTK+ toolkit, and it runs in
a GTK+-aware environment like GNOME, another connection might
already be established.
When PRIVATE is non-nil, a new connection is established instead of
reusing an existing one. It results in a new unique name at the bus.
