With transceiver integration, the resampling filter files were
dropped. This created a working resampling implementation for
the USRP2 / N200, but with spectrum irregulaties that likely
caused issues at longer range operation. Simply reinsert the
filter files and modify the filter initialization to use them.

Usage:
./configure --with-usrp1
Enable non-UHD USRP1 support through the gnuradio-based
driver. Requires gnuradio (libusrp) to be installed.
./configure --with-resample
Enable host-based 400ksps to 270.833ksps resampling.
Only supported for UHD devices. If not enabled, the GSM
sample rate is requested directly from the device.

Move push and pull of buffers into a dedicated file. This will
allow us to swap out resampling, non-resampling, and possibly
floating point device interfaces while presenting a single
floating point abstration in the interface itself.

Remove radio clock and vector interfaces into their own
files. This clears up and simplifies the radio interface
and, additionaly, prepares for a further split of the I/O
portion for optional resampler use.
