malloc(0) and realloc(ptr, 0) have implementation-defined behavior in
that the standard allows them to either return a unique pointer or a
nullptr for zero-sized allocation requests. Normalize by always using
a nullptr.
- Introduce node::malloc, node::realloc and node::calloc that should
be used throught our source.
- Update all existing node source files to use the new functions
instead of the native allocation functions.

Calling v8::Debug::DebugBreak() directly from the signal handler is
unsafe because said function tries to grab a mutex. Work around that
by starting a watchdog thread that is woken up from the signal handler,
which then calls v8::Debug::DebugBreak().
Using a watchdog thread also removes the need to use atomic operations
so this commit does away with that.

The `--security-revert={cvenum}` command line flag is a special purpose
flag to be used only in stable or LTS branches when a breaking change
is required to address a security vulnerability. Whenever a vulnerability
requires a breaking change, and a CVE has been assigned, the flag can
be used to force Node to revert to the insecure behavior that was
implemented before the fix was applied.
Note that this flag is intended to be used only as a last resort in the
case a security update breaks existing code. When used, a security
warning will be printed to stderr when Node launches.
The `--security-revert={cvenum}` flag takes a single CVE number as an
argument. Multiple instances of the `--security-revert={cvenum}` flag
can be used on the command line to revert multiple changes.
Whenever a new `--security-revert={cvenum}` is enabled, it should be
documented in the release notes and in the API docs.
Master and the first release of a new major (e.g. v6.0) should not have
any reverts available.
Every time a new `--security-revert={cvenum}` is added, there should be
a semver-minor bump in the stable and LTS branch.

Before this commit, sending a SIGUSR1 at program exit could trigger a
hard to reproduce race condition where `v8::Debug::DebugBreak(isolate)`
got called when the isolate was in the process of being torn down.
A similar race condition is in theory possible when sending signals
to two threads simultaneously but I haven't been able to reproduce
that myself (and I tried, oh how I tried.)
This commit fixes the race condition by turning `node_isolate` into
a `std::atomic` and using it as an ad hoc synchronization primitive
in places where that is necessary.
A bare minimum std::atomic polyfill is added for OS X because Apple
wouldn't be Apple if things just worked out of the box.

Previous logic didn't allow parent to propagate to the init callback
properly. The fix now allows the init callback to be called and receive
the parent if:
- async wrap callbacks are enabled and parent exists
- the init callback has been called on the parent and an init callback
exists then it will be called regardless of whether async wrap
callbacks are disabled.
Change the init/pre/post callback checks to see if it has been properly
set. This allows removal of the Environment "using_asyncwrap" variable.
