It is possible to bypass parameter validation in crypto.scrypt and
crypto.scryptSync by crafting option objects with malicious getters as
demonstrated in the regression test. After bypassing validation, any
value can be passed to the C++ layer, causing an assertion to crash
the process.

This commit modifies test-crypt-scrypt.js to use a regular expression
for the function name in the error message, similar to what is done for
the error code.
The motivation for this change comes from a case where we (Red Hat)
patch OpenSSL and the memory limit checking is done in a different
function, meaning that the function name from which this error
originates differs from that when linking to the OpenSSL version shipped
with Node.js.

This commit makes the crypto builtin an internal builtin, and
changes usage of the builtin from using process.binding('crypto')
to use internalBinding instead.

Scrypt is a password-based key derivation function that is designed to
be expensive both computationally and memory-wise in order to make
brute-force attacks unrewarding.
OpenSSL has had support for the scrypt algorithm since v1.1.0. Add a
Node.js API modeled after `crypto.pbkdf2()` and `crypto.pbkdf2Sync()`.
Changes:
* Introduce helpers for copying buffers, collecting openssl errors, etc.
* Add new infrastructure for offloading crypto to a worker thread.
* Add a `AsyncWrap` JS class to simplify pbkdf2(), randomBytes() and
scrypt().
