Add setjmp/longjmp for ARM and ColdFire to the codec lib, and use it in the Vorbis codec to better handle out of memory conditions (to exit rather than crash; the AAC codec could use it too). setjmp/longjmp comes from newlib 1.17.0 with a few minor changes (combine parts of some files, remove support for some architectures, change some ifdef's).
