[arm-allstar] Ezstream and NPTEE

[David McGough]

Hi Lee,

I've seen this same problem, but don't as of yet have a well tested
solution; I've experimented with a couple methods to fix this.  Resolving
this issue is on the To-Do list.  Ultimately, It'll probably require
either a modification to the "lame" software, or a software shim to detect
stream interruptions and restart the lame/ezstream software.
