Summary:                    [patch] UUI Information is treated as a null
terminated string, it's really a binary value.
Description: 
  UUI is being treated in libpri as a null terminated string, The truth is
that the standard actually even defines "\000" to be a marker for user
specific data. The implementation as it is wouldn't work for several custom
uses of UUI.
  The patch included makes that field a binary value. I also have included
a patch for asterisk, since then it takes a different approach to getting
and setting the UUI from the channel: we need to take into account that
this variable is a binary one. I created two new functions that allow to
set and get a variable from the channel by coding it in base64. Possibly
not the most elegant way, but it does the job pretty well.

We already have base64 encoding in main/utils.c. Please use that code :-)
