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.

Backport of 16bbeccd from master branch. Closes #4633.

Added the word 'has' to the sentence.
Closes #4652.

Handle Z_DATA_ERROR errors from inflateSetDictionary() gracefully.
Fixes the following assertion:

  node: ../src/node_zlib.cc:167: static void node::ZCtx::Process
  (uv_work_t*): Assertion `ctx->err_ == 0 && "Failed to set
  dictionary"' failed.
  Aborted (core dumped)

Fixes #4632.

Handle Z_NEED_DICT errors graciously. Fixes the following assertion:

  node: ../src/node_zlib.cc:161: static void node::ZCtx::Process
  (uv_work_t*): Assertion`ctx->dictionary_ != __null && "Stream
  has no dictionary"' failed.
  Aborted (core dumped)

Fixes #4632.

* npm: Upgrade to v1.2.2

* dns: make error message match errno (Dan Milon)

* tls: follow RFC6125 more stricly (Fedor Indutny)

* buffer: reject negative SlowBuffer offsets (Ben Noordhuis)

* install: add simplejson fallback (Chris Dent)

* http: fix "Cannot call method 'emit' of null" (Ben Noordhuis)

* Allow wildcards only in left-most part of hostname identifier.
* Do not match CN if altnames are present

This reverts commit 30e23704.

Works properly with b4b750b6

This reverts commit 45024e7b.

It's making test/simple/test-tls-check-server-identity.js fail:

  AssertionError: Test#4 failed: { host: 'b.a.com',
    cert: { subject: { CN: '*.a.com' } },
    result: false }
      at <omitted>/test/simple/test-tls-check-server-identity.js:201:10

This test starts two clustered HTTP servers on the same port.
It expects the first cluster to succeed and the second cluster
to fail with EADDRINUSE.

Reapplies commit cacd3ae0, accidentally reverted in a2851b62.

Reject negative offsets in SlowBuffer::MakeFastBuffer(), it allows
the creation of buffers that point to arbitrary addresses.

Make tools/install.py work with python 2.5

2.5 is still fairly widespread and does not include a json lib as
standard. Most python folk will have simplejson if they are in that
boat.

In general it seems a bit tricky to solve this perfectly...

see #4592

Fix the following exception:

  http.js:974
    this._httpMessage.emit('close');
                      ^
  TypeError: Cannot call method 'emit' of null
      at Socket.onServerResponseClose (http.js:974:21)
      at Socket.EventEmitter.emit (events.js:124:20)

      at process._tickCallback (node.js:386:13)
      at process._makeCallback (node.js:304:15)

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"

* npm: Upgrade to v1.2.0

  - node-gyp v0.8.2 (Nathan Rajlich)
  - Faster installs from github user/project shorthands (Nathan Zadoks)

* typed arrays: fix 32 bit size/index overflow (Ben Noordhuis)

* http: Improve performance of single-packet responses (Ben Noordhuis)

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.
