manual: Provide consistent errno documentation.

The @errno macro is extended to render the canonical error string in
every documented errno error.  Redundant entries and "???" are
removed.  Sixty-six errors now at least contain the error string as
the description, where no description (or "???") existed before.

	* manual/errno.texi: Remove redundant error strings.
	* manual/macros.texi (@errno): Render the error string in
	every description.
