Add padding sections to a zipr'd program where
the gap between two existing sections is greater
than a certain minimum boundary.

Added emt support for prefork+bilr+p1 (sketchy still), K6+NOG (seems stable with all xforms enabled).  I also did some peasoup/cfar fixes to support determunistic ID assignment for IRDB objects -- this was needed for marshaling because the EMT plugin uses ID matching to find identical objects (stack, scoop, instruction, etc.)  Next, I fixed bugs in p1transform where the p1.map wasn't getting proper IDs. Lastly, I added an option to zipr/elfwrite to disable bss-optimization, this was necessary for marshaling as that bss segments stay named/mapped to the binary and cannot be combined with other segments.

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.

No commit message

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.

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)
