This forces an even number of samples in the min or max case,
preserving the alignment of interleaved samples in the face
of RX overruns or TX underruns.

This is a custom build for USRP2 FPGA. It allows using a BasicRX or
LFRX board and feed two independent, real signals. In addition, instead
of the CIC/HB decimator, which optimizes frequency response, it uses an
integrate and dump decimator, which optimizes for time-domain impulse
response.
These changes have been made in dsp_core_rx.v:
* A second DDC has been added, sharing a frequency register with
the existing DDC.
* The output of the two DDCs are interleaved as I1 Q1 I2 Q2I ...
into the receive FIFO. This limits the host configured decimation
to 8 intead of 4. Use gr.deinterleave to recover the streams.
* The ADCs are hardcoded:
RX_A ==> DDC #1 I-input
0 ==> DDC #1 Q-input
RX_B ==> DDC #2 I-input
0 ==> DDC #2 Q-input
Thus, the input mux has been disabled.
* The CIC/HB decimator has been replaced by an integrate and dump at
the decimation rate.
* To assist with meeting timing, the external RAM has been disabled.
The basic application is to coherently sample two real IF streams and
downconvert to baseband, while minimizing the impulse response duration
of the resampling filters.

FPGA build to use integrate-and-dump decimator instead of CIC/HB combination. This provides a much shorter time duration impulse response for the same decimation rate, at the expense of worse stop-band rejection.
