Updates to udp source/sink (select(), wait, cleanup)

Use select() to avoid blocking on recv() in gr_udp_source (only known
way to avoid blocking on Cygwin).

Add wait argument to gr_udp_source to allow waiting for connection
or accepting lack of connection as EOF; add --no-wait option to...

Discard data in gr_udp_sink until receiver is started.

Also fixes warnings from gcc 4.3 and adds <boost/bind.hpp> for usrp2.

Use getaddrinfo in gr_udp_{source,sink}

Using getaddrinfo allows more common code between posix and winsock
systems. Remove unused variables and #include files. Close sockets
when done.

Changes to gr_udp_{source,sink} for MinGW

Initialize and cleanup after winsock DLL. Interpret winsock error
codes. Use DWORD instead of timeval for setting timeout.

Ignore ENOPROTOOPT return from setsockopt(SO_LINGER)

SO_LINGER is not valid for SOCK_DGRAM sockets on Windows, so we
expect setsockopt to return ENOPROTOOPT (invalid option for
protocol) on Cygwin and MinGW. If it happens on any other system
it should probably be ignored there, too.

Nevermind that last checkin. THIS is the right answer that doesn't have us possibly looking back at input item -1.

Fixes small bug by handling boundaries properly.

The oversampling rate can be only a few values as defined by the number of channels and input sample rate.
This now checks to make sure the user-specified rate is valid.
Also added some documentation to describe the oversample rate parameter.

Reworking variables to avoid recalculations/assignments.

Channelizer can now produce any rational ratio of the sample rate in [fs/N, fs] where fs is the input sample rate and N is the number of channels. The ratios work out to be N/i for i in [1, N].
