Previously, there was a window after starting the upload thread but
before the SIGTERM handler was installed, where receipt of SIGTERM
could have interrupted an in-progress upload. There was also the
possibility that a second SIGTERM sent after the exception handler
stopped running would interrupt an in-progress upload. By pulling the
signal handler out of ExceptionHandlerServer and into the main
function, these races are avoided.

I've heard/lived enough horror stories about AV, outbound-blocking
firewalls, etc. on Windows, that I think the best approach is to have
chrome.exe embed the majority of crashpad_handler and jump to it as
early as possible when running in that mode.
So, move most of crashpad_handler into a static_library with just main()
in the executable target.
