Move the internally defined symbol `fs.realpathCacheKey` to
the internal fs module, where it’s more appropriate.
The symbol was recently added in c084287a60, but since
`internal/fs` is only available in the v7.x branch, this

When both --debug-brk and --eval are set, and a filename is
specified, its full path is not set correctly, causing an error
for relative filenames with './' omitted.
For example, 'node --debug-brk -e 0 hello.js' throws an error.
Since the script referenced by the filename is never run anyway,
this change skips resolving its full path if both --debug-brk and
--eval are set.

Writing data to TLSWrap instance during handshake will result in it
being queued in `write_item_queue_`. This queue won't get cleared up
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.

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

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.
