Feature/calcuttj padding clean2

[calcuttj]

Includes padding additions for the issues presented by Gray. This is based off an earlier commit than the head of master because when I updated it, it wouldn't build correctly when configured for ups because of new additions to wscript

Gray gave thumbs up on ICARUS tests via email @HaiwangYu please take a look and merge if/when you are okay.

[HaiwangYu]

@brettviren, great! I will merge it soon.

@calcuttj, thanks for making this PR. I did some tests and this PR results a segfault for a sim-sigproc test for PDSP single APA. See page 5 and 6 of this note:
pr341.pdf

Could you look into this when having an opportunity? Thanks!
