doc: fix typo in crypto Hash.digest() note

Added the word 'has' to the sentence.
Closes #4652.
Add bytesWritten to tls.CryptoStream

This adds a proxy for bytesWritten to the tls.CryptoStream.  This
change makes the connection object more similar between HTTP and
HTTPS requests in an effort to avoid confusion.

See issue #4650 for more background information.

buffer: slow buffer copy compatibility fix

Fix issue where SlowBuffers couldn't be passed as target to Buffer
copy().

Also included checks to see if Argument parameters are defined before
assigning their values. This offered ~3x's performance gain.
buffer: clean up copy() asserts and tests

Argument checks were simplified by setting all undefined/NaN or out of
bounds values equal to their defaults.

Also copy() tests had a flaw that each buffer had the same bit pattern at
the same offset. So even if the copy failed, the bit-by-bit comparison
would have still been true. This was fixed by filling each buffer with a
unique value before copy operations.
buffer: error and misc cleanup

Changed types of errors thrown to be more indicative of what the error
represents. Also removed a few unnecessary uses of the v8 fully
quantified typename.

Backport of 16bbecc from master branch. Closes #4633.
buffer: remove minor Buffer::Copy deoptimizations

* Omit ToObject() call. Buffer::Data() and Buffer::Length() know how
  to deal with Values.

* Don't check if the argument is undefined because it realistically
  never is and undefined->integer coercion achieves the same thing.
