Add generic functions for (U)Int read/write operations on Buffers. These
support up to and including 48 bit reads and writes.
Include documentation and tests.
Additional work done by Trevor Norris to include 40 and 48 bit write
support. Because bitwise operations cannot be used on values greater
than 32 bits, the operations have been replaced with mathematical
calculations. Regardless, they are still faster than floating point
operations.

Performance improvement by moving checks for floating point operations
to JS and doing the operation on a protected internal function that
assumes all arguments are correct. Still abort if the operation
overflows memory. This can only be caused if the Buffer's length
property isn't the same as the actual internal length.

Running fill() with an empty string would cause Node to hang
indefinitely. Now it will return without having operated on the buffer.
User facing function has been pulled into JS to perform all initial
value checks and coercions. The C++ method has been placed on the
"internal" object.
Coerced non-string values to numbers to match v0.10 support.
Simplified logic and changed a couple variable names.
Added tests for fill() and moved them all to the beginning of
buffer-test.js since many other tests depend on fill() working properly.

When replying to a HEAD request, do not attempt to send the trailers and
EOF sequence (`0\r\n\r\n`). The HEAD request MUST not have body.
Quote from RFC:
The presence of a message body in a response depends on both the
request method to which it is responding and the response status code
(Section 3.1.2). Responses to the HEAD request method (Section 4.3.2
of [RFC7231]) never include a message body because the associated
response header fields (e.g., Transfer-Encoding, Content-Length,
etc.), if present, indicate only what their values would have been if
the request method had been GET (Section 4.3.1 of [RFC7231]).

Unexport the http.parsers freelist. It was originally exported by Ryan
in commit 0003c701 but the commit log doesn't mention why and it's never
been documented. It's unclear if there are any users.
The lifecycle of parser objects changed recently and it seems better to
not let people shoot themselves in the foot so easily.
If it turns out there are actually users, we can always re-export it
again - probably under a slightly different name, to force people to
update their code to the new way of things.

Currently, cluster workers can be removed from the workers list in three
different places:
- In the exit event handler for the worker process.
- In the disconnect event handler of the worker process.
- In the disconnect event handler of the cluster master.
However, handles for a given worker are cleaned up only in one of these
places: in the cluster master's disconnect event handler.
Because these events happen asynchronously, it is possible that the
workers list is empty before we even clean up one handle. This makes
the assert that makes sure that no handle is left when the workers
list is empty fail.
This commit removes the worker from the cluster.workers list only when
the worker is dead _and_ disconnected, at which point we're sure that
its associated handles are cleaned up.

replace unescaper during parsing. However, the function was only
being used as a fallback for when the native decoder throws (on a
malformed URL). This patch moves the call to the native function and
the try/catch around it into querystring.unescape then has the parser
always invoke it, so that an override will always be used.

This is the Node side of the fix for Node's cluster module on Windows.
https://github.com/joyent/node/issues/7691
The other required part is
https://github.com/joyent/libuv/pull/1384
Windows and Unix return certain socket errors (i.e. EADDRINUSE) at
different times: bind on Windows, and listen on Unix.
In an effort to hide this difference, libuv on Windows stores such
errors in the bind_error field of uv_tcp_t, to defer raising it at
listen time.
This worked fine except for the case in which a socket is shared in
a Node cluster and a bind error occurs.
A previous attempt to fix this (
d1e6be14603da36fe00e
) was flawed becaused in an attempt to relay the error at the JS level
it caused the master to start accepting connections.
With this new approach, libuv itself is relaying the bind errors,
providing for a uniform behavior of uv_tcp_listen.
