    this._httpMessage.emit('close');
                      ^

Fixes #4586.

For example, to cross-compile from my OS X laptop for Raspberry Pi, you would
do something like:

  $ make binary BINARYNAME=node-v`python tools/getnodeversion.py`-linux-arm-pi \
      DESTCPU=arm CONFIG_FLAGS="--dest-os=linux"

Fix an out-of-bound read/write bug due to integer wrapping. Reported by
Dean McNamee.

Raise a TypeError when the argument to send() or sendto() is anything
but a Buffer.

Fixes the following assertion:

  $ node -e 'require("dgram").createSocket("udp4").send("BAM")'
  node: ../../src/udp_wrap.cc:220: static v8::Handle<v8::Value>
  node::UDPWrap::DoSend(const v8::Arguments&, int): Assertion
  `Buffer::HasInstance(args[0])' failed.
  Aborted (core dumped)

Fixes #4496.

The example clarifies now that diff[0] * 1000000000 + diff[1] equals
the result in nanoseconds.

CPU time values must be Numbers, not Integers, as they can be too large
for Integers on 32 bit platforms.

When building custom `node` versions (e.g., floating features/fixes from
different versions) it's often useful to specify a custom tag which
easily identifies build when invoking `node -v`.

Introduce a way to specify this tag in `node_version.h` file or by
running `./configure --tag="<tag>"`. Insert it right after the patch
version (and before `-pre`, if build is not a release).

Apply the same optimization to res.end(buf) that is applied to res.end(str).

Speeds up `node benchmark/http_simple_auto -k -c 1 -n 25000 buffer/1`
(non-chunked response body) by about 750x. That's not a typo.

Chunked responses:

  $ cat tmp/http-chunked-client.js
  // Run `node benchmark/http_simple` in another terminal.
  var http = require('http'), url = require('url');
  var options = url.parse('http://127.0.0.1:8000/buffer/1/1');
  options.agent = new http.Agent({ maxSockets: 1 });
  for (var i = 0; i < 25000; ++i) http.get(options);

Before:

  $ time out/Release/node tmp/http-chunked-client.js
  real    16m40.411s
  user    0m9.184s
  sys     0m0.604s

After:

  $ time out/Release/node tmp/http-chunked-client.js
  real    0m5.386s
  user    0m2.768s
  sys     0m0.728s

That's still a 185x speed-up.

Fixes #4415.

Use res.end() for the final chunk so we can benchmark the 'hot path' shortcut
in lib/http.js that packs the headers and the body into a single packet.

Man pages go into $PREFIX/man on OpenBSD, not $PREFIX/share/man.

Make parser errors bubble up to the ClientRequest instead of the underlying
net.Socket object.
