John Reiser 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.

John Reiser 52400e2561 /proc/self/exe now is optional 
... for the benefit of 'unshare', 'chroot', etc.
If not present, then upx run-time stub unmaps all pages of original main program.

Markus F.X.J. Oberhumer a1d090a6fd src/stub: add a "clang-format off" directive 2023-10-15 10:55:15 +02:00
John Reiser 0515be4334 LZMA on AMD64 had bug in calling sequence, leading to random exit(127) 
LzmaDecode randomly decided that the input had ended in the middle,
because of error in interface between ELFMAINX and the decoder.

Thanks to Kevin Gosse!

John Reiser 5de83a606e Cleanup after Thierry Fauck changes for ppc64le. 
We need a "UPX standard" compiler in order to re-compile the stubs for ppc64le;
meanwhile use Thierry's "pre-compiled" stubs.
Revert powerpc stubs to those produced by UPX standard powerpc.405-linux-gcc-3.4.5.
Cleanup the workarounds that Thierry used because he lacked upx-stubtools 20130920.
ARMv8 (64-bit) compiles but is incomplete and does not run yet.
