performance improvements in elfwriter and log size reduction in zipr.cpp.  note:  please implement a 'very verbose' option to zipr if you need these full logs, because they are way too big.

These comments and additional output give clarity 
to the case where two free ranges abut and need to 
be merged together.

had elfwriter use .text instead of .zipr_text for first .text segment.  gdb hates not having a .text segment.

Updates to elfwrite to handle more segments, new cfar configs typed out, and scons added to get-packages.

many updates esp. regarding interfacing NOL/NOH with ps-analyze, set-interpreter assertions being hit, writing an elf header that's bigger than 4k, etc.

Remove DetermineWorstCaseInsnSize as public interface and force callers to specify account_for_fallthrough when calling other WC*S functions.

1. There are now opening/closing sizes for
   each dollop entry. 

2. Each plugin must identify whether it
   plopped the instruction or not (as 
	 opposed to simply plopping bytes in the
	 dollop entry opening and closing
	 sections).

1. Update semantics of how plugins determine
   the size and space of the dollop that they
	 will plop. 
2. Add sorting for plugin invocation based on
   lexigraphical sorting.

support in zipr for better mapping of scoops->section types, support in move-globals to move only the necessary bits for adding to the .got.plt, and relocation tables, etc.  also first support in CFI for multi-module support (not working yet, but can add relocations and got entries for dladdr, dlsym, and,zestcfi)

1. A dollop can not plop itself atop its own pin
2. Dollops that fallthrough to one another will now
   be properly aligned adjacent to one another even
	 if they are not coalesced by zipr-proper. This
	 basically gives the plugin the ability to preplace
	 fallthrough dollops consecutively without having
	 to trick zipr into doing it for them.

Update to zipr to support relro scoops, and fix to move globals/SplitScoop to handle file size properly.
