Also, de-compressing arm64 shlib restores .init_array[0],
although supposedly *_RELATIVE relocation should overwrite.

John Reiser 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

John Reiser 82ed25bb44 Major fix 64-bit un_shlib_1() and unpack(), but not --android-shlib 
Also canUnpack() is really a 'bool' which sets overlay_offset
when 'true'; confusing!

John Reiser 03436d2415 Bug in handling DT_GNU_HASH table. 
Fix includes a more-general and stronger heuristic to find the end of
GNU_HASH table when there is no ElfXX_Shdr for it.  64-bit only for now.
(This is needed to help prevent SIGSEGV when processing tampered .exe.)
