From ce28185909272d2aebc0e8279a4ab2c3cca16c02 Mon Sep 17 00:00:00 2001
From: Tom Rondeau <tom@trondeau.com>

Subject: ctrlport: blocks: added controlport support to add_const_XX blocks.
Removed add_const_XX template concept and reimplemented as separate
blocks for bb, ss, ii, ff, and cc support. The work functions should
be converted into VOLK calls.
