Fixes the build on FreeBSD <= 9 with the default compiler.

Fixes #4186.

This test is only passing because it's skipped normally.

Just sends a buffer to a server, which echoes it back, and then measures
the Gbits/second.  Very similar to throughput.js, but using a single
process, so that it's possible to dtrace and get the jsstack frames for
profile comparison.

Disabled the following unit tests:

* test-eio-race.js
* test-eio-race2.js
* test-eio-race4.js

These tests are known to fail on busy boxes due to being timing sensitive,
and are deemed not meaningful tests.

See https://github.com/joyent/node/issues/4272

Fixes #4272.

Fixes the following error message:

  TypeError: exceptions must be old-style classes or derived
  from BaseException, not str

Fixes #4303.

OR'ing together two large values, like `SSL_OP_ALL | SSL_OP_NO_TICKET`,
produces a negative number. To wit:

  assert((0x80000000 | 0x4000) === -0x7fffc000); // true
  assert((0x80000000 | 0x4000) ===  0x80004000); // false!

It's easy to work around by doing a logical shift, like this:

  assert((0x80000000 | 0x4000) >>> 0 ===  0x80004000); // true

But that's not very intuitive. Let's be more lenient in what we accept.

Use Number::New() instead of Integer::New(). The latter wraps large values,
e.g. 0x80000000 becomes -2147483648 instead of 2147483648.

Thin archive needs binutils >= 2.19, disable it for supporting old ar
even if static libraries are linked within a local build.

Patch by Henry Rawas and Scott Blomquist.

* fix gyp build
* don't require libexecinfo, it's not there
* libpthread doesn't implement sem_timedwait(), fall back to sem_wait()

Fixes #4287.

This commit contains one additional patch that makes gyp work on DragonFlyBSD,
see https://codereview.chromium.org/11348152/ for details.

Make HandleSSLError() correctly process a zero status code: sometimes it
indicates an error and sometimes it doesn't.

The purpose of this file was to remap the old libeio API to the new one.
We dropped libeio in ee77a6a9 and this file has been broken ever since.

Ergo, remove it.

Don't interpret floating point numbers, e.g. ".1234", as REPL commands.

Fixes #4268.

Many assertion tests are duplicated in buffer.js. These few could be easily
removed and still have all tests pass.

While updating the readline test cases to test both "terimal: false" and
"terminal: true" mode, it turned out that the test case testing utf8 chars
being sent over multiple write() calls was failing. The solution is to use
a string_decoder instance when parsing the "keypress" events.

Before this commit, readline was inconsistent in whether or not it would emit
"line" events with or without the trailing "\n" included. When "terminal"
mode was true, then there would be no "\n", when it was false, then the "\n"
would be present. However, the trailing "\n" doesn't add much, and most of the
time people just end up stripping it manually.

Part of #4243.

* Added isIP method to make use of inet_pton to cares_wrap.cc
* Modified net.isIP() to make use of new C++ isIP method.
* Added new tests to test-net-isip.js.

Don't define the _LARGEFILE_SOURCE and _FILE_OFFSET_BITS flags, they're
inherited from libuv now.
