funcs/func_jitterbuffer: Tweak documentation
This patch merely reformats and cleans up a bit of the jitterbuffer documentation for the wiki. git-svn-id: https://origsvn.digium.com/svn/asterisk/branches/13@420639 65c4cc65-6c06-0410-ace0-fbb531ad65f3

+ <para>Jitterbuffers are constructed in two different ways.
+ The first always take three arguments: <replaceable>max_size</replaceable>,
+ <replaceable>resync_threshold</replaceable>, and <replaceable>target_extra</replaceable>.
+ Alternatively, a single argument of <literal>default</literal> can be provided,
+ which will construct the default jitterbuffer for the given
+ <replaceable>jitterbuffer type</replaceable>.</para>
+ <para>The arguments are:</para>
+ <para><replaceable>max_size</replaceable>: Length in milliseconds of the buffer.
+ Defaults to 200 ms.</para>
+ <para><replaceable>resync_threshold</replaceable>: The length in milliseconds over
+ which a timestamp difference will result in resyncing the jitterbuffer.
+ Defaults to 1000ms.</para>
+ <para>target_extra: This option only affects the adaptive jitterbuffer. It represents
+ the amount time in milliseconds by which the new jitter buffer will pad its size.
+ Defaults to 40ms.</para>
