e85e8bec5d New option --catch-sigsegv on amd64, arm64, arm.v4a 
Catch SIGSEGV during de-compression, and print state info
("auto debug") using /proc/self/maps and gdb.
This was motivated by suspicion of unreliable hardware
which triggered "Heisenbugs": a crash which cannot be reproduced.
If SIGSGV occurs without the "auto debug" info, then that
implies an error user code after de-compression, often when
user code accesses /proc/self/exe, which is not the un-compressed file.

f6e3df69eb stub/amd64-win64.pe.h matches upx-v4.2.4 
so that anti-virus checkers of apps for 64-bit Windows that are newly-
compressed by upx should not complain about new matches with malware.
This costs a few bytes and a small fraction of cycles in NRV2
de-compressors, but is considered to be a tolerable concession
to the cesspool environment of software for Microsoft Windows.
