How messy would option 1 be? Option 2 (or 3) more closely follows the
existing UHD model where the shared code is mainly limited to the
transport. I think that would be the best approach unless option 1 can
be done very cleanly.

What is the difference between option 2 and 3? Does option 2 create a
second impl class within the usrp2 directory? I think a separate
directory is appropriate.

b100 and usrp1 implementations were created based on copies of
existing usrp2 / e100 code without explicit class reuse. For example,
b100 / e100 / usrp1 exist separately, but share the same ad9862 codec.
There is some copied code between the three codec versions, but that
was less messy than creating a unified codec impl for all three.
