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.)

05ff7e35a1 Warn for big shell scripts, and send them to --force-execve. 
Also propagte error code when execve() fails for compressed shell,
to avoid confusion of `hlt` ==> SIGSEGV.

9e8de4abe5 i386: new stub strategy to avoid problems with early mmap layout 
The stub occupies the same region that execve() would create
for the original progam.  The stub copies everything to a new area,
erases the original region, replaces it with the de-compressed
program, and erases the copy of itself via the escape hatch.
The copy is inexpensive via mmap() of /proc/self/exe.

5a94136764 "python -c" works, so python is a shell. [However, scripts often use: 
#!/usr/bin/env python
instead of
	#!/usr/bin/python
because for a long time python was not "blessed" by living in /usr/bin;
many users have python in /usr/local or some other place in $PATH.
And /usr/bin/env does not take "-c".]
