On some systems (e.g., Debian/lenny) UDP errors are reported on the
following send() or recv() call. To avoid having errors (such as
ECONNREFUSED) from an old connection showing up on the first write
to a new connection, we do a recv() on disconnect() to flush them.
This may not work for all errors on all systems, but it works in
some simple cases of interest.

Remove source address specifications for sink; add connect() and
disconnect() to sink; add get_port() to source; add optional EOF
signaling (using zero-length packets) to sink and source; modify
dial_tone, vector, and audio examples to match new code; add qa
test case.

d_object to delete all of the plotting widgets. As far as Valgrind tells me, this cleans up my memory leaks although libqt and libqwt still have some of their own.
This checkin also disables the Waterfall3D plotting. It wasn't working anyway, but was also causing its own segfault upon deletion. Once it's working and deleting nicely, it will be re-enabled.

buffer as opposed to a best effort based on a hand-made timer. The interval between GUI updates is settable through the qtsink_X objects with set_update_time(newtime). This update makes the plotting much more stable. It also fixes the time scale of the waterfall plot to actually mean the right thing.

This change was needed because gr_ofdm_sampler derives directly from
gr_block, but functions (from the runtime's point of view) as a
decimator. It takes many items in to produce a single output
item. Without this change, values of fft_size > ~4096 would result
in the scheduler complaining that it could never fullfil the block's
request for samples.
When deriving from gr_sync_interpolator or gr_sync_decimator, their
constructors set the hint automatically.

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
dial_tone_sink.py.
Remove system dependencies from .h files; remove unused data members
and (useless?) public open and close functions.

Subject: [Discuss-gnuradio] tx_samples.cc is not accepting the gain
parameter input.
Hi,
I observed that tx_samples.cc is not accepting the gain input parameter
(ie., -g option). I just changed like this in my code.
Its working, so posting the changes. If it is acceptable please take it.
best regards,
srinivas.
