On Windows the default UDP send buffer size is 8192. OSX default is
9216. On Linux default is 212992. The values are too small on Windows
and OSX. This cannot make good use of the A-MPDU of 802.11n (64KB),
which is the most common network for Cast Streaming.

We have also seen strong evidence that the default buffer size is
limiting, e.g. long packet queuing delay on Windows, p2p socket seeing
a lot of EWOULDBLOCKs.

This code uses pacer maximum burst size (in bytes) as the send buffer
size. Also added an option "send_buffer_min_size" to allow application
to choose an even larger value for send buffer size.

r299567 disabled SSLv3 fallback. This change adds an enterprise policy option
to control this value so that enterprises can reenable the fallback if they
need it.

This option is in contrast to the one added in r299755. That one allows
enterprises to be more aggressive in disabling SSLv3, while this one is
intended for those who need to more slower that Chrome's default.

Revert of [Mac] Enter should trigger the buttons in the new avatar bubble. (patchset #1 id:1 of https://codereview.chromium.org/644023002/)

Reason for revert:
This doesn't do what it's supposed to do, and after more discussions with groby@, Enter is really only used for default buttons on Mac, not all buttons.

Original issue's description:
> [Mac] Enter should trigger the buttons in the new avatar bubble.

We need the ability to observe the Mojo message pump in order to correctly
resolve promises at the end of microtasks triggered by signaling Mojo handles.

Another approach James and I discussed for this CL was to trigger
MessageLoop::TaskObserver, but that requires a PendingTask, which we don't
have. I investigated removing the PendingTask argument from
MessageLoop::TaskObserver, but it's used in a number of tests. Instead, this CL
follows the approach used by MessagePumpLibevent and introduces a specialized
observer interface for the message pump.

There is a bug in Mavericks for applications linked against OSX 10.8 and
earlier. It requires Screens Have Separate Spaces to be enabled, and for the
window to be on a secondary screen. When AppKit Fullscreen is invoked on the
window, its final frame is 22pt too short.

This CL detects when these specific conditions occur so that the window's size
can be fixed.

Note: This is a bug buried in AppKit. Playing with methods like
-[NSWindowDelegate window:willUseFullScreenContentSize:] will not fix the
problem.

Mechanical change that adds instrumentation required to locate the source of jankiness (i.e. a long-running fragment of code executed as a part of the task that causes jank) in the code. See the bug for details on what kind of jank we are after.
A number of similar CLs were landed, and none of them caused issues. The code of the instrumentation is highly optimized and is not expected to affect performance. The code simply creates a diagnostic task which is identical to ones created by PostTask or IPC message handlers.
Landing as TBR since this is a mechanical, safe and temporary change.

Before:
* We'd send the message "containing" the message pipe (handle) first.
* Upon receiving it, the other side would create an endpoint (and
  dispatcher, etc.)
* The other side then sent a message back indicating the new ID (and
  telling the first side to run the message pipe.
* Upon receiving that "run" message, the first side would start sending
  messages for that message pipe.

This makes for rather complicated handshaking, which would only get more
complicated if, e.g., the second side wanted to forward the message pipe
handle that it received to someone else (e.g., over another channel).

Now:
* We "remotely allocate" an ID for the other side and send a message
  telling it to create an endpoint with that ID.
* We forward all the messages queued to that message pipe endpoint
  immediately (since we already know the destination ID).
* We send the message "containing" the message pipe (handle).
* The other side then creates a dispatcher and associates it with the
  (already-existing) endpoint.

Still to do:
* We need to track IDs that we've allocated for the remote side more
  carefully (in case of wrap-around, to avoid collisions).
* Convert everything over to the "attach and run" mode of operation (and
  possibly rename "attach and run" to something shorter), and delete the
  various separate "attach" and "run" methods.

Commit c4a3f88c ("TestWebServer needs to
use a free port") has caused TestWebServer to use a random port number
in each invocation.

This does not play well with tests that assume the server will be
running on a specific port (for example, an HTML asset trying to do XHR
whose contents cannot be changed at runtime).

start() and startSsl() can now be passed an optional port number; if it
is being used, the server will fail to start like it did before the
commit mentioned above.
