This change cleans up outstanding comments on #3032. It improves error
handling when no isolate file is provided and adds the --prof-process
flag to the node binary which executes the tick processor on the

Commit a9c0c65 ("src: define getpid() based on OS") made src/env.cc
use `GetCurrentProcessId()` on Windows for the PID in log messages.
`GetCurrentProcessId()` is also what is used by libuv, OpenSSL and V8.
This commit makes `process.pid` use `GetCurrentProcessId()` instead of
`_getpid()` for consistency.

This feature supports the Intel Vtune profiling support for JITted
JavaScript on IA32 / X64 / X32 platform. The advantage of this profiling
is that the user / developer of NodeJS application can get the detailed
profiling information for every line of the JavaScript source code.
This information will be very useful for the owner to optimize their
applications.
This feature is a compile-time option. For windows platform, the user
needs to pass the following parameter to vcbuild.bat: "enable-vtune"
For other OS, the user needs to pass the following parameter to
./configure command: "--enable-vtune-profiling"

Before this commit, sending a SIGUSR1 at program exit could trigger a
hard to reproduce race condition where `v8::Debug::DebugBreak(isolate)`
got called when the isolate was in the process of being torn down.
A similar race condition is in theory possible when sending signals
to two threads simultaneously but I haven't been able to reproduce
that myself (and I tried, oh how I tried.)
This commit fixes the race condition by turning `node_isolate` into
a `std::atomic` and using it as an ad hoc synchronization primitive
in places where that is necessary.
A bare minimum std::atomic polyfill is added for OS X because Apple
wouldn't be Apple if things just worked out of the box.

ALPN takes precedence over NPN and the server does not send NPN

Previous logic didn't allow parent to propagate to the init callback
properly. The fix now allows the init callback to be called and receive
the parent if:
- async wrap callbacks are enabled and parent exists
- the init callback has been called on the parent and an init callback
exists then it will be called regardless of whether async wrap
callbacks are disabled.
Change the init/pre/post callback checks to see if it has been properly
set. This allows removal of the Environment "using_asyncwrap" variable.

Overall construction time of Typed Arrays is faster in JS, but the
problem with using it normally is zero-fill of memory. Get around this
by using a flag in the ArrayBuffer::Allocator to trigger when memory
should or shouldn't be zero-filled.
Remove Buffer::Create() as it is no longer called.
The creation of the Uint8Array() was done at each callsite because at
the time of this patch there was a performance penalty for centralizing
the call in a single function.

This adds a new `--tls-cipher-list` command line switch
that can be used to override the built-in default cipher
list. The intent of this is to make it possible to enforce
an alternative default cipher list at the process level.
Overriding the default cipher list is still permitted at
the application level by changing the value of
`require('tls').DEFAULT_CIPHERS`.
As part of the change, the built in default list is moved
out of tls.js and into node_constants.h and node_constants.cc.
Two new constants are added to require('constants'):
* defaultCipherList (the active default cipher list)
* defaultCoreCipherList (the built-in default cipher list)
A test case and doc changes are included.
A new NODE_DEFINE_STRING_CONSTANT macro is also created in
node_internals.h
When node_constants is initialized, it will pick up either
the passed in command line switch or fallback to the default
built-in suite.
Within joyent/node, this change had originaly been wrapped
up with a number of other related commits involving the
removal of the RC4 cipher. This breaks out this isolated
change.

Buffers now have a maximum size of Smi::kMaxLength, as defined by V8.
Which is ~2 GB on 64 bit and ~1 GB on 32 bit.
The flag --use-old-buffer allows using the old Buffer implementation.
This flag will be removed once V8 4.4 has landed.
The two JS Buffer implementations have been split into two files for
simplicity.
Use getter to return expected .parent/.offset values for backwards
