In several places throughout the code we write directly to stderr
to report warnings (deprecation, possible eventemitter memory leak).
The current design of simply dumping the text to stderr is less
than ideal. This PR introduces a new "process warnings" mechanism
that emits 'warning' events on the global process object. These are
invoked with a `warning` argument whose value is an Error object.
By default, these warnings will be printed to stderr. This can be
suppressed using the `--no-warnings` and `--no-deprecation` command
line flags. For warnings, the 'warning' event will still be emitted
by the process, allowing applications to handle the warnings in custom
ways. The existing `--no-deprecation` flag will continue to supress
all deprecation output generated by the core lib.
The `--trace-warnings` command line flag will tell Node.js to print
the full stack trace of warnings as part of the default handling.
The existing `--no-deprecation`, `--throw-deprecation` and
`--trace-deprecation` flags continue to work as they currently do,
but the exact output of the warning message is modified to occur
on process.nextTick().
The stack trace for the warnings and deprecations preserve and point
to the correct call site.
A new `process.emitWarning()` API is provided to permit userland
to emit warnings and deprecations using the same consistent
mechanism.
Test cases and documentation are included.

Based on the conversation in #4243 this implements a way to increase
and decrease the size of the thread pool used in v8.
Currently v8 restricts the thread pool size to `kMaxThreadPoolSize`
which at this commit is (4). So it is only possible to
decrease the thread pool size at the time of this commit. However with
changes upstream this could change at a later date.
If set to 0 then v8 would choose an appropriate size of the thread pool
based on the number of online processors.

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
provided isolate file.
