Merge branch 'probe'
Added gr_probe_signal_X and gr_probe_signal_vX.
core: added volk version of add_ff.
core: new multiply_const_ff and multiply_ff blocks done using Volk.
core: moving multiply_const_ff from gengen to general to take advantage of volk.
Also adds SSE and AVX and unaligned Volk versions for this.
core: moving multiply_cc and multiply_const_cc out of gengen and into general so they can make use of volk calls.
QA code now explicitly tests the cc versions of these blocks.
cmake: fixed up swig deps properly for make -j*
Also took the time to fix up the swig index file generation.This may have not-been auto-regenerating before as well.
swig: fix rules for generated index files
gr: changed the way trellis/gengen generated.i is made
gr: the CMakeLists.txt took a chill pill
trellis: performed generation re-work on gr-trellis lib
core: re-work gengen generation (hope its simpler)
core: attempt at fixing up generation logic in gengen (filter, trellis TODO)
gr: squashed cmakelists.txt into one commit
