child_process: remove .track option

Since net.Server's `connection` property is deprecated now, we don't
need API to track socket's state to keep `connection`s value up-to-date.
typed arrays: fix DataView endianness regression

Fix an off-by-one error introduced in 9fe3734 that caused a regression
in the default endianness used for writes in DataView::setGeneric().

Fixes #4626.
dtrace: fix generation of v8 constants on freebsd

Every constant is certainly 4 bytes now, but freebsd's objdump utility
prints out odd byte sequences (5-bytes, 6-bytes and even 9-bytes long)
for v8's data section. We can safely ignore all upper bytes, because all
constants that we're using are just `int`s. Since on all supported
platforms `int` is 32bit long (and anyway v8's constants are 32bit too),
we ignore all higher bits if they were read.
gyp: fix build with dtrace support on FreeBSD

Fix undefined reference to `gelf_getsym`... and other undefined symbols
from libelf, by adding `-lelf` to linker options on FreeBSD.

http: close connection on 304 and chunked encoding

Force the connection to close when the response is a 304 Not Modified
and the user has set a "Transfer-Encoding: chunked" header.

RFC 2616 mandates that 304 responses MUST NOT have a body but node.js
used to send out a zero chunk anyway to accommodate clients that don't
have special handling for 304 responses.

It was pointed out that this might confuse reverse proxies to the point
of creating security liabilities, so suppress the zero chunk and force
the connection to close.
buffer: remove float write range checks

Removed range checks when writing float values, and removed a few
includes and defines. Also updated api docs to reflect that invalid 32
bit float is an unspecified behavior.
build: Add some gyp artifacts to .gitignore
http: close connection on 204 and chunked encoding

This is similar to commit 2cbf458 but this time for 204 No Content
instead of 304 Not Modified responses.

When the user sends a 204 response with a Transfer-Encoding: chunked
header, suppress sending the zero chunk and force the connection to
close.
gitignore: ignore v8.log files
streams: Support objects other than Buffers

We detect for non-string and non-buffer values in onread and
turn the stream into an "objectMode" stream.

If we are in "objectMode" mode then howMuchToRead will
always return 1, state.length will always have 1 appended
to it when there is a new item and fromList always takes
the first value from the list.

This means that for object streams, the n in read(n) is
ignored and read() will always return a single value

Fixed a bug with unpipe where the pipe would break because
the flowing state was not reset to false.

Fixed a bug with sync cb(null, null) in _read which would
forget to end the readable stream
streams2: Handle sync read callbacks nicely
test: Add test for negative stream drain counter
tls: make slab buffer's size configurable
