ed0665407a More: prefer movzbl over movb fetch to register 
Avoids hardware failure of writing 0x00 instead of the fetched byte.
1 cycle faster, 1 byte larger (but often recouped later when OR of 32-bits).
Avoid changing win*pe.S for now.

ea2a190bd1 ELF2 main programs pass src/testsuite and upx-testsuite-v2 
Decompressing lzma required many adjustments.
Backwards compatibility probably is broken for
    stub/amd64-win64.pe.h
    stub/arm64-win64.pe.h
Also: shared libraries need memfd_create.

c36977f0b1 ELF: amd64-linux main programs use 2-step de-compressor 
The first $ARCH to move to 2-step de-compressor for ELF main programs.
De-compressor uses memfd_create to comply with strictest SELinux
settings (no PROT_WRITE on any PROT_EXEC page).
First step de-compressor always uses NRV2B to de-compress the second step,
and the second step can use a different de-compressor for each PT_LOAD.

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.

If not enough room on last page of .text, and ElfXX_Ehdr not PF_X,

e7f1e99a5e Merge branch 'jreiser' into devel 
O_BINFO simplifies stubs on linux Elf;
PowerPC64 (big endian: Apple Macintosh G5) and PowerPC* cleanup;
-fpie simplification; shlib for arm64, amd64.

A big merge due to suspending activity on 'devel' branch
during stabilization for release of UPX-3.94.
There were intermediate merges with private branch 'jreiser',
and attempted rebase onto 'devel' did not go well.
Verfication of cases ({ET_EXEC, -fpie, shlib} x {$ARCH}) is in progress.
