usrp2: make the booty smaller than the number of recv frames
...
This may fix some of our woes when the host cannot keep up.
That is, with a smaller booty, the managed buffers will get
freed up and the call to get buffer will never block waiting
for a buffer to become free. This has several side effects:
1)
Overflows are more likely to occur in the pirate thread.
Pirate-based overflows will overwrite old packets, whereas
socket-based overflows will discard newer incoming packets.
2)
The pirate thread will continue to pull in async packets
rather than loosing them in a socket-based overflow.

uhd: replaced frame params for the zero copy interfaces with a device address
...
the device address gives a key, value pair of infinite optional capabilities
added a cast option to the device address to cast string to type T
added call to the zero_copy_if to get send and recv frame sizes
changed the usrp2 impl to calculate recv/send spp from the data transport
