This fixes a race condition in the watchdog timer used for vm timeouts.
The condition would terminate the main stack's execution instead of the
code running under the sandbox.

Adds flags that marks WinCtrlCHandlerRoutine as disabled instead of
removing it. Trying to remove the controller from the controller
handle itself leads to deadlock.

When a vm script aborted after a timeout/signal interruption, test
whether the local timeout/signal watchdog was responsible for
terminating the execution.
Without this, when a shorter timer from an outer `vm.run*` invocation
fires before an inner timeout, the inner timeout would throw an error
instead of the outer one, but because it did not witness the timeout
itself, it would assume the termination was the result of a signal
interruption.

- Adds the `breakEvalOnSigint` option to `vm.runIn(This)Context`.
This uses a watchdog thread to wait for SIGINT and generally works
just like the existing `timeout` option.
- Adds a method to the existing timer-based watchdog to check if it
stopped regularly or by running into the timeout. This is used to
tell a SIGINT abort from a timer-based one.
- Adds (internal) `process._{start,stop}SigintWatchdog` methods to
start/stop the watchdog thread used by the above option manually.
This will be used in the REPL to set up SIGINT handling before
entering terminal raw mode, so that there is no time window in
which Ctrl+C fully aborts the process.

Switch from running the loop with UV_RUN_ONCE to UV_RUN_DEFAULT, because
it's possible that the poll returns earlier than expected and thus the
timer is not run on a single interation.
The loop is not stopped either from the timer callback or from the async
handle's.

is no justifiable reason to also require that it be included in every

Now that we are building with C++11 features enabled, replace use
of NULL with nullptr.
The benefit of using nullptr is that it can never be confused for
an integral type because it does not support implicit conversions
to integral types except boolean - unlike NULL, which is defined
as a literal `0`.
Mechanically replace assert() statements with UNREACHABLE(), CHECK(),

The exceptions are src/node.h and src/node_object_wrap.h because they

Eliminate a race condition between uv_async_send and the closing of the
corresponding handle.
Also made errors in Watchdog constructor call abort()
Fixes#6088
Previous code was calling uv_loop_delete() directly on a running loop,
which led to race condition aborts/segfaults within libuv. This change
changes the watchdog thread to call uv_run() with UV_RUN_ONCE so that
the call exits after either the timer times out or uv_async_send() is
called from the main thread in Watchdog::Destroy(). The timer/async
handles are then closed and uv_run() with UV_RUN_DEFAULT is called so
that libuv has a chance to cleanup before the thread exits. The main
thread meanwhile calls uv_thread_join() and then uv_loop_delete() to
complete the cleanup.
Add a watchdog class which executes a timer in a separate event loop in
a separate thread that will terminate v8 execution if it expires.
Add timeout argument to functions in vm module which use the watchdog
if a non-zero timeout is specified.
