b535098017 Merged features/inband -r4812:5218 into trunk. This group of changes includes: 
* working stand-alone mblock code
 * work-in-progress on usrp inband signaling

usrp now depends on mblock, and guile is a dependency.

5a17f48e73 Adds capability to independently delay the Auto T/R switching signal by a configurable number of clock ticks, to allow users to precisely align their T/R output with the pipeline delays in the transmitter. 
There are two new registers:

FR_ATR_TX_DELAY (7'd2)
FR_ATR_RX_DELAY (7'd3)

...and the corresponding db_base.py methods to set them:

db_base.set_atr_tx_delay(clock_ticks)
db_base.set_atr_rx_delay(clock_ticks)

These methods are inherited by all the daughterboard objects so you can
call them from your scripts as:

subdev.set_atr_tx_delay(...)

...where 'subdev' represents the daughtercard object you're working with.

The FPGA synthesis for the 2 RXHB, 2 TX case expands from 95% to 96%,
with no additional synthesis messages or impact on timing.

886cbb6ba4 New FPGA binaries (.rbfs). These include fixes for the scaling in the CIC decimator so that signals are now roughly leveled, independent of the decimation rate. Decimating by 44 now works too ;)

706545cb6c Applied patch from Brett Trotter that stuffs zeros into the head of the tx signal processing pipeline when the Tx FIFO is empty. 
This results in the DACs outputing zeros when there's no data, unless
the tx pipeline is disabled on the host.
