Merge branch 'jreiser-elfstub' into devel
...
New stub strategy on Linux: Linux adds too many other segments
to the address space: [vdso], [sigpage], ...; and qemu might
arrange them differently. Thus the only reliable mappings
are the PT_LOAD of the compressed file itself; all other
address space is unknown! First, the compressed file uses
.bss to occupy all unused pages up to the original brk(0).
Then at run time, the stub gets another mapping of /proc/self/exe,
and uncompresses the user program on top of the original pages.
[*BSD unchanged for now?]

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.

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.
