docs: installing generated _doc.i files under autotools.
docs: autotools Makefile.am generates empty swig_docs .i files; builds in autotools and cmake.
The autotools build does not auto-generate the Python documentation for each block like we do with the cmake build, but the empty .i files are required to build things regardless. The swig_doc.py and doxyxml files are distributed with the autotools build in case someone wants to generate this on their own (see README.doxyxml for how to do this)....
work on swig docs, added to core and digital
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.
Merge remote branch 'jblum/master'
reed-solomon: fixed the signed/unsigned warnings in the RS code.
Some of these had to be done through type-casting since changingthe actual data type would cause the tests to fail. make teststill passes.
I'm sorry but llrintf had one of the best conversions of all time
usrp: these guys shouldn't still be here...
core: really fixed this on 32-bit machines (actually tested). Forced to promote to a 64-bit int to handle the overflow, so this is going to take a hit on 32-bit machines.
core: fixed float_to_int for 32-bit machines.
