cfa8107ab9 src: make sort order deterministic, next try 
We cannot compare pointers as they may point to qsort-local objects.
And we must make sure that cmp(a,b) always agrees with cmp(b,a).

d8395d8c42 Fix usage of _te32/_te64/_te16 for Elf classes 
How did it ever work?  UPX_RSIZE_MAX_MEM of 768MiB, Elf32_Off of only
32-bits, and preponderance of little-endian and small positive integers
hides many mis-uses of _te64/_te32.
ELF does not help: e_phnum, e_shnum, Elf32_Section, Elf64_Section are all
16-bit, but sh_info and sh_link are 32-bit.
Templatizing p_elf.h (following the example of p_mach.h) failed
because of complexity.  (Plus too many special cases of ELF where 32-bit
and 64-bit are not parallel.)

c75d7a685d src: major cleanups, introduce new eXtended Span class 
- initial minimally invasive eXtended Span implementation
- rename ptr_diff to ptr_diff_bytes
- move some files to util subdir
- lots of cleanups
- start using the new checked pointers - this needs some real-world testing
