66df7389d2 Refactoring: pass upx_compress_config_t to Packer::compressWithFilters() 
so that formats can set conf_lzma.max_num_probs.

Also renamed compression parameters to use cconf & cresult.

268e322e1c Extra parameter for compressWithFilters and packExtent, 
to fix 2-pass problem with --brute on linux/elf386.
Only one decompression method is allowed, chosen by
smallest output for .text; but Elf headers come first.

664a82e7c9 Start re-organizing the packing of Elf, by making Elf32 come first, 
with Big endian and Little endian derived from it.
I386 still uses the old way, but PowerPC (both Linux and Darwin [Mac])
use the new way.
