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.

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.

https://github.com/upx/upx/issues/341   i386 .so decompression
https://github.com/upx/upx/issues/609   armv7 .so on Android
https://github.com/upx/upx/issues/625   amd64 .so execution
https://github.com/upx/upx/issues/654   armv7 .exe
Not yet: .so on MIPS, PowerPC, PowerPC64

c34fe09a79 Revamp --android-shlib 
Android "Oreo" wants to deal with ElfXX_Shdr[].  So splice 4KiB into PT_LOAD[0]
with an "extra" copy of them.  This requires careful relocation processing.
It also costs a page at run time, and an average of a page in the file
(depending on fragmentation at the boundary between r-x and rw- .)
