PN update. changed some logging data, changed how functions with low/no coveage are validated, add functionality to validate the entire program, including shared objects, at once.

I will not attempt validation on functions that haven't been covered. In theory, they should validate immediately when validated using recursive validation. The intuition is we might actually have coverage for these functions because of errors in how coverage is generated.

Optimized PN, sort vectors of functions to validate by the number of boundaries found by the infernces for those functions. The concept is that if there are 3 or fewer variables, these layouts are essentially P1, so they should validate immediately. By sorting them, when recurisve validation is used, hopefully a larger portion of functions will be validated immediately, if all these "safer" functions are grouped together.

PNTransformDriver will now perform shuffle validation, if appropriate. To determine if shuffle validation is appropriate, I also changed PNStackLayout.hpp to return if shuffle validation is appropriate for a layout. 

Also enforce that a.ncexe is the first file to be modified, and minor code clean up and tweaks to logging information.

PN Will not register modificaitons, but instead will accumulate modifications that succeed. This is a hack because zsh will not pass if I delay modifications until the end. 

Also a few additions to logging, error logging, and comments. Some minor cleanup as well.

PNTransformDriver.cpp: important comments as to what padding is actually added for a variable.

PN optimization. PN will now do a binary search algorithm to find bad modifications. All functions with coverage are now validated, and validated faster than previous version that only validated if coverage was above the threshold. 

This version does not have shuffle validation, I will add that feature in a future update. It was easier to remove it for this optimization. Typically this is only used for Main. 

New logging summary output including how many functions are modified with high coverage, low coverage and no coverage.

PNTransformDriver.cpp using basename of shared objects to match file name stored in db. This is a temporary fix due to the way shared objects are currently stored in the db.

coverage will get the basename of a shared object absolute address to compare against the stored url of a shared object. This should be corrected such that the db stores the absolute path of the shared object and comparison does not require me to take the basename.

I had a change of heart, a summary report of functions exceeding the PN threshold is given by PN now, not coverage.cpp. This way the summary is based on the threshold passed on PN not a hard coded 50% like I had it before.

coverage.cpp, prints out to stdout the total number of non-plt funcs (functions that don't begin with '.') that exceed 50% coverage.

Second, and last partial commit which now fully updates the toolchain for the manual testing infrastructure.
