dtmf/spandsp: Move dtmfdetect to use libspandsp
Remove our copy of the tone_detect.c file and use the original from libspandsp. Also move the element to the spandsp plugin.

- * SECTION:element-dtmfdetect
- * @short_description: Detects DTMF tones
- *
- * This element will detect DTMF tones and emit messages.
- *
- * The message is called <classname>&quot;dtmf-event&quot;</classname> and has
- * the following fields:
- * <itemizedlist>
- * <listitem>
- * <para>
- * gint <classname>type</classname> (0-1):
- * The application uses this field to specify which of the two methods
- * specified in RFC 2833 to use. The value should be 0 for tones and 1 for
- * named events. Tones are specified by their frequencies and events are
- * specfied by their number. This element can only take events as input.
- * Do not confuse with "method" which specified the output.
- * </para>
- * </listitem>
- * <listitem>
- * <para>
- * gint <classname>number</classname> (0-16):
- * The event number.
- * </para>
- * </listitem>
- * <listitem>
- * <para>
- * gint <classname>method</classname> (2):
- * This field will always been 2 (ie sound) from this element.
- * </para>
