John Reiser 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.

John Reiser 067895fa5f Fix brk+munmap in folded stubs for main programs 
qemu emulating a compressed ET_EXEC revealed an access to ElfXX_Phdr
on the discarded side of brk() during cleanup. qemu was more aggressive
than the Linux kernel implementation of brk().

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

John Reiser 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.
