examples: Reworked locations and installation of examples.
All python and GRC examples directly associated with a top-level component are now in that examples directory. Examples are split into c++, python, and grc dirs but are all installed into $prefix/share/gnuradio/examples/<component>.

+This is generated by the 1/2 AWGN code (5 7) operated twice, ie,
+(xk+1 xki) [xk-1 xk-2] -> [xk+1 xki].
+We also puncture the first (MSB) bit and Gray map the symbols.
