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.)

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- .)

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.

Merge branch 'jreiser' into devel

O_BINFO simplifies stubs on linux Elf;
PowerPC64 (big endian: Apple Macintosh G5) and PowerPC* cleanup;
-fpie simplification; shlib for arm64, amd64.
A big merge due to suspending activity on 'devel' branch
during stabilization for release of UPX-3.94.
There were intermediate merges with private branch 'jreiser',
and attempted rebase onto 'devel' did not go well.
Verfication of cases ({ET_EXEC, -fpie, shlib} x {$ARCH}) is in progress.
