Set the `req.buffer` property, which serves as a way of keeping
a `Buffer` alive that is being written to a stream, on the C++
side instead of the JS side.
This closes a hole where buffers that were temporarily created
in order to write strings with uncommon encodings (e.g. `hex`)
were passed to the native side without being set as `req.buffer`.

If user make some actions during (e.g. stepOver native call)
that requests program break and disconnect DevTools frontend then
AgentImpl won't be disconnected until other message from frontend.
The root of issue:
1. Inspector requests program break.
2. User requests disconnect (e.g. refresh page with DevTools frontend).
3. On program break V8Inspector call runMessageLoopOnPause on
V8NodeInspector.
4. Message loop will wait until next message from frontend.
5. After message Agent will be disconnected.
We can dispatch all pending message on step 3 to solve a problem.

Commit 2272052 ("net: bind to `::` TCP address by default") from
April 2014 seems to have accidentally changed the default listen
address from 127.0.0.1 to 0.0.0.0, a.k.a. the "any" address.
From a security viewpoint it's undesirable to accept debug agent
connections from anywhere so let's change that back. Users can
override the default with the `--debug=<host>:<port>` switch.

When node is running with --inspect flag, default console.log,
console.warn and other methods call inspector console methods in
addition to current behaviour (dump formatted message to stderr and
stdout). Inspector console methods forward message to DevTools and
show up in DevTools Console with DevTools formatters. Inspector
console methods not present on Node console will be added into it.
Only own methods on global.console object will be changed while in a
debugging session. User are still able to redefine it, use
console.Console or change original methods on Console.prototype.

Make the inspector code easier to reason about by restructuring it
to avoid manual memory allocation and copying as much as possible.
An amusing side effect is that it reduces the total amount of memory
used in the test suite.

Fix handle leaks in Buffer::New() and Buffer::Copy() by creating the
handle scope before looking up the env with Environment::GetCurrent().
Environment::GetCurrent() calls v8::Isolate::GetCurrentContext(), which
creates a handle in the current scope, i.e., the scope created by the
caller of Buffer::New() or Buffer::Copy().

Current implementation tracks connected/disconnected status separately
which potentially introduces race condition.
This change introduces notion of session IDs and also posts
connect/disconnect events into the same queue as the messages. This way
Node knows what session given response belongs to and can discard
messages if the frontend for that session had disconnected.
This also fixes an issue when frontend was unable to attach to V8
instance that was running infinite loop.

Disable stdio buffering, it interacts poorly with printf() calls from
elsewhere in the program (e.g., any logging from V8.) Unbreaks among
other things the `--trace_debug_json` switch.
Undoes commit 0966ab99 ("src: force line buffering for stderr"), which
in retrospect is not a proper fix. Turning on line buffering fixed a
flaky test on SmartOS but the test wasn't failing on other platforms,
where stderr wasn't line-buffered either. Mark the test flaky again,
it failed once in a run of 333 tries on the smartos-64 buildbot.
Disabling buffering should be safe even when mixed with non-blocking
stdio I/O because libuv goes to great lengths to reopen the tty file
descriptors and falls back to blocking I/O when that fails.
