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'.
