Before this change, _unrefActive would keep the unrefList sorted when
adding a new timer.
Because _unrefActive is called extremely frequently, this linear scan
(O(n) at worse) would make _unrefActive show high in the list of
contributors when profiling CPU usage.
This commit changes _unrefActive so that it doesn't try to keep the
unrefList sorted. The insertion thus happens in constant time.
However, when a timer expires, unrefTimeout has to go through the whole
unrefList because it's not ordered anymore.
It is usually not large enough to have a significant impact on
performance because:
- Most of the time, the timers will be removed before unrefTimeout is
called because their users (sockets mainly) cancel them when an I/O
operation takes place.
- If they're not, it means that some I/O took a long time to happen, and
the initiator of subsequents I/O operations that would add more timers
has to wait for them to complete.
With this change, _unrefActive does not show as a significant
contributor in CPU profiling reports anymore.

Previously, 'configure' would not return an exit status
if gyp blows up. This can be tested via:
date >> node.gyp ; ./configure && echo A-OK
You will get "A-OK" even though gyp had failed.

In very unlikely case, where `deflateInit2()` may return error (right
now happening only on exhausting all memory), the `ZCtx::Error()` will
be called and will try to `Unref()` the handle. But the problem is that
this handle was never `Ref()`ed, so it will trigger an assertion error
and crash the program.

The test wasn't checking directly that an assertion was thrown. Instead,
it was checking that spawn did not sucessfully spawn a non-existent
command.
However, the command chosen, dir, exists in GNU coreutils, so it exists
on Linux (though not on BSD derived OS X). The test as written passed on
Linux, even with the TypeError it is supposed to be checking for deleted
from spawn(). It would also pass on Windows if a ls.exe existed.
The approach is unnecessarily obscure, assert.throw() is for asserting
code throws, using it is more clear and works regardless of what
commands do or do not exist.

Add a test that goes through the whole matrix of:
- command line options (--enable-ssl*)
- secureOptions
- secureProtocols
and makes sure that compatible test setups actually work as expected.
The test works by spawning two processes for each test case: one client
and one server. The test passes if a SSL/TLS connection from the client
to the server is successful and the test case was supposed to pass, or
if the connection couldn't be established and the test case was supposed
to fail.
The test is currently located in the directory 'test/external' because
it has external dependencies.
* openssl: Update to 1.0.1j (Addressing multiple CVEs)
* uv: Update to v0.10.29
* child_process: properly support optional args (cjihrig)
* crypto: Disable autonegotiation for SSLv2/3 by default (Fedor Indutny,
Timothy J Fontaine, Alexis Campailla)
This is a behavior change, by default we will not allow the negotiation to
SSLv2 or SSLv3. If you want this behavior, run Node.js with either
`--enable-ssl2` or `--enable-ssl3` respectively.
This does not change the behavior for users specifically requesting
`SSLv2_method` or `SSLv3_method`. While this behavior is not advised, it is
assumed you know what you're doing since you're specifically asking to use
these methods.
adds a note to the crypto docs passing along
the advice that openssl gives about what
key derivation function they recommend.

Always set ssl2/ssl3 disabled based on whether they are enabled in Node.
In some corner-case scenario, node with OPENSSL_NO_SSL3 defined could
be linked to openssl that has SSL3 enabled.
In the case of a pipe'd input, i.e. from the CI the fd will be a PIPE
and when listen() is called it will return ENOTSOCK instead of EINVAL.

The order of the callbacks is non-deterministic, so don't expect the
error messages to come back in the same order every time, instead just
verify they are expected messages.
This change disables SSLv2/SSLv3 use by default, and introduces a
command line flag to opt into using SSLv2/SSLv3.
SSLv2 and SSLv3 are considered unsafe, and should only be used in
situations where compatibility with other components is required and
they cannot be upgrade to support newer forms of TLS.
Because of constant-timeness change made in openssl-1.0.1j the error is
no longer returned from EVP_DecryptFinal_ex. Now it just return 0, and
thus the error message does not contain proper error code. Adapt to this
change, there is not much that we could do about it.
