V8's interpreter performs stack checks both at the call site and at the
function entry. A recursive function could therefore trigger stack
overflow at two different source locations. Instead of recursion, call
JSON.stringify on a deeply nested array.

Commit c5b07d4 ("lib: fix beforeExit not working with -e") runs the
to-be-evaluated code at a later time than before because it switches
from `process.nextTick()` to `setImmediate()`.
It affects `-e 'process.on("message", ...)'` because there is now a
larger time gap between startup and attaching the event listener,
increasing the chances of missing early messages. I'm reasonably
sure `process.nextTick()` was also susceptible to that, only less
pronounced.
Avoid the problem altogether by evaluating the code synchronously.
Harmonizes the logic with `Module.runMain()` from lib/module.js
which also calls `process._tickCallback()` afterwards.

There are places in the code base where setTimeout() or
setInterval() are called with just a callback and no duration/interval.
The timers module will use a value of `1` in that situation.
An unspecified duration or interval can be confusing. Did the original
author forget to provide a value? Did they intend to use setImmediate()
or process.nextTick() instead of setTimeout()? And so on.
This change provides a duration or interval of `1` to all calls in the
codebase where it is missing. `parallel/test-timers.js` still tests the
situation where `setTimeout()` and `setInterval()` are called with
`undefined` and other non-numeric values for the duration/interval.

Commit 93a44d5 ("src: fix deferred events not working with -e") defers
evaluation of the script to the next tick.
A side effect of that change is that 'beforeExit' listeners run before
the actual script. 'beforeExit' is emitted when the event loop is
empty but process.nextTick() does not ref the event loop.
Fix that by using setImmediate(). Because it is implemented in terms
of a uv_check_t handle, it interacts with the event loop properly.

- 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.
