Merged eb/binstats -r3848:3906 into trunk. These changes
(1) fix a problem with gr_feval* where when called from a live
flowgraph, they resulted in the call back into Python occuring without
holding the Global Interpreter Lock causing a SIGSEGV.

(2) add gr_bin_statistics_f which combines statistics gathering...

Implements ticket:3 and fixes ticket:42. The common functionality of
run_tests.in for Python QA has been extracted into run_tests.sh in the
top-level and the individual run_tests just invoke that with the right
path parameters. Also fixed Cygwin 'make check' bug by adding fix by...

Trial fix for ticket:45

Changed interpretation of second argument to gr_buffer_add_reader from
"history" to "nzero_preload". If the argument is 0, no zeros are
preloaded into the buffer. This is a less surprising interpretation
than the old behavior, which when passed a zero, inserted buffersize-1...

Several enhancements to gr-trellis and gnuradio-examples/python/channel-coding:
-Added fsm constructor for generating FSM directly from the
generator matrix of binary convolutional codes.
-Added functionality to fsm class to compute the best way to
go from any state to any other state (useful for termination)...
