It's easier to interpret an "SEGV_MAPERR", "FPE_INTDIV", or "ILL_ILLOPC"
rather than "code 1".
Alongside the decoded instruction pointer from the previous commit, we
now get a message like:
Received signal 11 (SIGSEGV), code SEGV_MAPERR, at address 0x00005637dd5c1346, for address 0x0000000000000004

From the user and machine context provided in the signal handler.

This is the infrastructure code, without actually getting the
instruction pointer from the machine context.

Extracted from existing code; I'm going to need it for some GDB/LLDB
commands in an upcoming commit.

For regular strings, it'll call strlen() for us, removing the need of
our doing it. We just have to remove the one case where we were passing
iovec into it: make asyncSafeToString() return a string_view too.

It's common between the two implementations, though currently completely
unused on Windows because we don't start debuggers.

This further reduces the size of the header.

This declutters the header from code that doesn't need to be there and
is only used in the .cpp anyway. This code used to be in qtestcase.cpp
before commit c0014becca2cd376eadd5c8a0265e5cf47c9aa01, which we now
amend. Additionally, since Windows code doesn't need to be async-safe
anyway, we can simplify it.
I'm also going to need the toHexString() lambda in another place.

This file is convoluted and hard to read due to #if all over the place.
Let's split the two very different implementations.
This is the conclusion, which removes the Unix code from the Windows
file and the Windows code from the Unix file.
Drive-by remove the unnecessary header #includes.

This is the first commit, which just copies the files around without any
changes, to help with Git history.
