This patch adds USRP2 device support and future support for
other UHD based devices. On receive, a sample buffer class,
which is indexable by timestamps, is used to temporarily
hold data until the requested samples are available.
On transmit, samples are sent immediately unless sample
alignment is known to be off - during startup or after the
occurrence of underruns or other errors. To regain
synchronization at these moments, timestamps are compared
against the current device time and dropped unless there
exists significant delay margin to physically arrive at the
device before deadline.
