a13b4d10d9 After upx-3.96, the de-compressing stub for ELF moved 
... so unpack() of newly-compressed ELF by upx-3.96 now says
"CantUnpackException: need a newer version of UPX"

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

e7ca5c54ff Fix --brute for p_lx_elf.cpp, which compresses multiple pieces 
Force all pieces to use the same de-compressor.
(Future: allow each PT_LOAD to choose its own.)
Has minor wobbles due to page alignment, and size of de-compressor.
64-bit only for now.

700c8730cf Modernize libc usage: stop using off_t, use modern printf. 
C++ 14 is here, and old versions of MSVC and MSVCRT have
haunted us long enough.

f383629282 compressWithFilters(..., inhibit_compression_check=0) // SourceForge bug 3541020 
Not good to check compression ratio on every block when blocksize < file_size,
as when --force_execve of Elf > 0x80000 bytes.
