Add an ExitCode enum class and use it throughout the code base
instead of hard-coding the exit codes everywhere. At the moment,
the exit codes used in many places do not actually conform to
what the documentation describes. With the new enums (which
are also available to the JS land as constants in an internal
binding) we could migrate to a more consistent usage of the
codes, and eventually expose the constants to the user land
when they are stable enough.

When intializing the constructor for cluster master we are heavily using
a generic structure, but the effect of passing arguments that are
related to shared_handle is that there is a stale argument passed.
We can avoid such scenarios as all the remaining entities are being
destructured from the message object.

Historically `error.errno` of system errors thrown by Node.js
can sometimes be the same as `err.code`, which are string
representations of the error numbers. This is useless and incorrect,
and results in an information loss for users since then they
will have to resort to something like
`process.binding('uv'[`UV_${errno}`])` to get to the numeric
error codes.
This patch corrects this behavior by always setting `error.errno`
to be negative numbers. For fabricated errors like `ENOTFOUND`,
`error.errno` is now undefined since there is no numeric equivalent
for them anyway. For c-ares errors, `error.errno` is now undefined
because the numeric representations (negated) can be in conflict
with libuv error codes - this is fine since numeric codes was
not available for c-ares errors anyway.
Users can use the public API `util.getSystemErrorName(errno)`
to retrieve string codes for these numbers.
