Subject: Merged r6271:6278 from jcorgan/t182 into trunk. Implements
ticket:182.
Created new top-level component, gr-utils, to hold commonly used utility
scripts (originally in gnuradio-examples). These now install into the
system path, allowing their use from wherever.
Reorganization of gnuradio-examples component:
* Commonly used utility scripts moved from python/usrp into gr-utils.
* Examples now install into $(prefix)/share/gnuradio/examples/...
* Channel coding examples moved into gr-trellis/src/examples, now install
from there, only if gr-atsc itself is going to built and installed.
* ATSC example scripts now install into example hierarchy
* Cruft has been moved into 'limbo' in repository, do not get installed
Trunk passes 'make distcheck'.
