Drop the previous Mutex and ScopedLock classes from platform files.
Add new Mutex, RecursiveMutex and LockGuard classes, which are
designed after their C++11 counterparts, so that at some point
we can simply drop our custom code and switch to the C++11
classes. We distinguish regular and recursive mutexes, as the
latter don't work well with condition variables, which will be
introduced by a followup CL.

Thread class was receiving an isolate parameter by default.
This approact violates the assumption that only VM threads
can have an associated isolate, and can lead to troubles,
because accessing the same isolate from different threads
leads to race conditions.
This was found by investigating mysterious failures of the
CPU profiler layout test on Linux Chromium. As almost all
threads were associated with some isolate, the sampler was
trying to sample them.
As a side effect, we have also fixed the DebuggerAgent test.
Thanks to Vitaly for help in fixing isolates handling!

the only platform that it works on is linux (using the prctl API to set the
names of the threads). Other platforms are setup to build properly if the
flag is set, but their thread names are not currently set.

This issue was raised by Brett Wilson while reviewing my changelist for readability. Craig Silverstein (one of C++ SG maintainers) confirmed that we should declare one namespace per line. Our way of namespaces closing seems not violating style guides (there is no clear agreement on it), so I left it intact.

The object delivered to the debug message handler contains additional information on the current break handling the messages.
Clients which require just JSON message parsing can simply get the JSON using the GetJSON message on the message object to still have the previous behaviour.
NewMessageHangler(const v8::Debug::Message& message) {
v8::String::Value val(message.GetJSON());
OldMessageHandler(Vector<uint16_t>(const_cast<uint16_t*>(*val), val.length()));
}
Refactored some of the debugger code to use internal handles instead of API handles. Also changed Object to JSObject is some places.
The access to the active context when the break occurred is still not implemented. I will add this in a new CL, as this one is quite big already.

ENABLE_DEBUGGER_SUPPORT is enabled by default unless it is on Android platform.
On Android platform, it can also enabled by passing -DENABLE_DEBUGGER_SUPPORT flag to the compiler.
This should not affect any existing build (I hope, cross my fingers) except the build in real Android environment (in other word, it only affects me now).
There are lot of room for code refactoring in stead of using #ifdef all over the place. I will leave this to v8 folks.

During bind and listen socket errors are now handled. If the listen socket is occoupied the agent will retry its bind operation until success or shutdown.
Added orderly shutdown of the debugger agent both with and without a client connected.

The debugger agent listens on a TCP/IP port for a remote debugger connection. When such a connection is established the debuger JSON protocol is communicated between the agent the the remote debugger. The messages containing the JSON protocol has a RFC-822 like header with a Content-Length field and with the body containing the JSON in UTF-8 encoding.
The D8 shell has option --debugger-agent to start the debugger agent.
