This commit removes two truthy checks for object properties that
are immediately followed by a strict equality check. The other
item in the comparison is guaranteed to be a function by this
point in the code, so the truthy check is redundant.

Writing data to TLSWrap instance during handshake will result in it

until the end of the handshake.
Technically, it gets cleared on `~TLSWrap` invocation, however this
won't ever happen because every `WriteWrap` holds a reference to the
`TLSWrap` through JS object, meaning that they are doomed to be alive
for eternity.
To breach this dreadful contract a knight shall embark from the
`close` function to kill the dragon of memory leak with his magic
spear of `destroySSL`.
`destroySSL` cleans up `write_item_queue_` and frees `SSL` structure,
both are good for memory usage.

As shown in https://github.com/nodejs/node/issues/9096, the offset and
end value of the `slice` call are coerced to numbers and then passed to
`FastBuffer`, which internally truncates the mantissa part if the number
is actually a floating point number. This actually affects the new
length of the slice calculation. For example,
> const original = Buffer.from('abcd');
undefined
> original.slice(original.length / 3).toString()
'bc'
This happens because, starting value of the slice is 4 / 3, which is
1.33 (approximately). Now, the length of the slice is calculated as
the difference between the actual length of the buffer and the starting
offset. So, it becomes 2.67 (4 - 1.33). Now, a new `FastBuffer` is
constructed, with the following values as parameters,
1. actual buffer object,
2. starting value, which is 1.33 and
3. the length 2.67.
The underlying C++ code truncates the numbers and they become 1 and 2.
That is why the result is just `bc`.
This patch makes sure that all the offsets are coerced to integers
before any calculations are done.

Commit 93a44d5 ("src: fix deferred events not working with -e") defers

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
