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.

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().

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.
