doc: buffer: clarify typed array construction

It's possible to construct a typed array from a buffer but the buffer
is treated as an array, not a byte array as one might expect.

Fixes #7786.

buffer: improve {read,write}{U}Int* methods

Increase the performance and simplify the logic of Buffer#write{U}Int*
and Buffer#read{U}Int* methods by placing the byte manipulation code
directly inline.

Also improve the speed of buffer-write benchmarks by creating a new
call directly to each method by using Function() instead of calling by
buff[fn].

stream: only end reading on null, not undefined

The [Stream documentation for .push](http://nodejs.org/api/stream.html#stream_readable_push_chunk_encoding)
explicitly states multiple times that null is a special cased value
that indicates the end of a stream. It is confusing and undocumented
that undefined *also* ends the stream, even though in object mode
there is a distinct and important difference.

The docs for Object-Mode also explicitly mention null as the *only*
special cased value, making no mention of undefined.

repl: fix multi-line input

The refactor in 3ae0b17c broke the multiline input's visual appearence.
While actually switching to this mode, the `...` prefix is not
displayed.

Additionally, account only SyntaxErrors that are happening at the parse
time, everything else should not be switching repl to the multiline
mode.

V8 seems to ignore the default value for want_separate_host_toolset and
