Something I've been itching to do for a while now. A minor optimization in app_voicemail.
Since the dtable in base_encode always gets populated with the same values every time and never
changes, make it static and const and only initialize it once. Also, there's no reason to
define BASEMAXINLINE twice, so remove the redundant #define.
