usrp1 previously had 1 rx and 1 tx dsp with multiple freq params,
it now has N and M dsps each with one freq param.
This is more consistent with the multi-dsp model.
The hack here is to only apply stream commands and sample rate changes to dsp0.

Created new type ref_vector for representing a vector of pointers.
Can be created from std::vector or a pointer.
Removes the convenience constrcutors for send/recv, its not needed.
Removes malloc/free overhead when using send/recv with pointer.

Leave the tx digital always enabled, flush with zeros is enough to turn it "off".
Fixed the flush routine to send something (when zero) to ensure zeros go out.

today we added shutoff the DAC when not transmitting using EOB as an indicator
added various other features and cleaned up code for soft time control

The max send spp is the frame size minus the alignment padding.
This allows us to copy a remainder into a new buffer and always
commit multiples of the alignment size (512 bytes).
Reworked the managed send buffer implementation to handle the above.
Uses only managed memory, and only mem-copied under the alignment.

converted all size_t timeout_ms to double timeout
bounded and alignment buffer now take double timeout
added timeout to device::send and zero_copy_if::get_send_buff

used dummy packers and unpackets that have a header size of zero
created wrapper around the data transport to handle non-512 multiple sends
honor the eob flag on send to flush the send buffer

Get clock values from clock control, where the master setting lives.

everything that should have two is now stored into a dictionary of slot to type
the set and get functions are now bound with a third argument for dboard slot
the dboard iface has yet to be completed with the correct registers for a vs b
