Refactor debug info generation

The primary purpose of this patch is to refactor the way the -dbg packages and associated files are generated. In the original code it's being done in one operation with the splitting and stripping of the files within the populate_packages. The code was split from there, and then modified in two steps to get to the final version.

The first step implemented the new method where the split occurs and then the strip occurs. This makes it easier to tailor each of them as things change in the future.

The second path refactors this to eleminate multiple file walks and file identification processing. The behavior of the system is the same, only things are more efficient.

The fourth patch is simply a bug fix to some pre/post actions I found while diagnosing and debugging. This patch is separate from the rest of the refactoring and should be merged, even if the others are not.

FYI, I also did timing on this to see how it impacted system performance. The times below affect ONLY the do_package [and later] stages, on my specific host. (8 core with a 16/16 build configuration)

Original before these changes:

real    37m29.035s
user    41m14.322s
sys     31m0.006s

After the changes -- using "debian" style debuginfo, i.e. the same output as the original style:

real    36m48.160s
user    42m17.636s
sys     31m47.846s

After the changes -- using the new "fedora" style debug info:

real    38m48.793s
user    44m9.822s
sys     37m48.803s

The first two are nearly the same. Any deviation is likely due to the additional hardlink/symlink processing.

The fedora style introduces additional steps in the process that rewrite source code references and duplicate specific source code files into the -dbg directory for later (easier) debugging.
