VS2013 does not support defaulting move constructor and assignment
operator. This adds explicit definitions of those methods for two
classes.
This fix is required because we still support building addons with
VS2013 and the incompatibility is in v8.h.

Since V8 5.9 V8 installs a default signal handler for some signals
when creating a default platform instance that prints a stack trace.

However, Node already does the same thing, so it would seem like the
two different stack traces would be printed; also, the V8 handler
would lead to a `SIGSEGV` under some circumstances, rather than
letting the abort continue normally.

Resolve this by disabling V8’s signal handler by default.

There are a few patches that likely have to be included in this PR #14582

I can reproduce the libxmljs failures reported by CITGM :/ I assume it’s the same kind of problem that made us introduce setTimeouts in our garbage collection tests but it might be good if somebody had a closer look.

(The errors occur both when using pre-compiled binaries and when compiling from source, so it’s not an ABI compatibility thing.)

They are not specific to this PR, they have been in master for a while. (I did not track CitGM well enough to know when they appeared, so I assumed they were always there)

They aren't on v6.x fwiw. 8.x needs a bit of ecosystem love

Yeah, if @refack is right it’s probably a V8 5.9+ thing but nothing to worry about
