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.)

adb0ca8250 Many changes for ELF shared libraries on Linux and Android 
Handling more than 2 PT_LOAD (and thus more than 1 executable PT_LOAD)
required extensive changes.  But the bonus is the infrastructure
to support a different (de-)compression algorithm for each PT_LOAD.
