Support profiler stack sampling in any situation. After this change, almost all profiler ticks (except GC ones) have a stack sample data associated.

Tested under Linux, OS X, and Windows.

Cleaned up the handling of strings moving, so strings moved by GC and strings changing representation are handled equivalently.

When the debugger agent terminates the used port can be stuck in TIME_WAIT for some time depending on the OS and the state of the socket. With this change will allow the debug agent to start listening on a port still in TIME_WAIT. During development of both V8 and embedding applications this makes it much easier to restart an application using the debugger agent.

This also makes it possible to run the tests involving the debugger agent multiple times without failure.

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.

Removed the close method for socket and added shutdown instead. The shutdown method is the one to use when terminating socket communication. The close call is in the destructor.

The FreeBSD version is a copy of the Linux version which should work on FreeBSD as well. According to the FreeBSD documentation clock_gettime is part of the standard C library so the assumption is that no additional link libraries is required for FreeBSD.
