In-app messaging to communicate the imminent 32-bit deprecation to 32-bit-only
users.

In Google Chrome-branded builds, show an infobar at startup to users with
32-bit-only systems, and add a message to the about page for those users
advising that automatic updates will soon stop because the system
configuration is about to become unsupported.

A provision is made to change this message to an "end-of-the-line" message for
the final 32-bit-compatible build. When this switch is flipped, the autoupdate
status and promotion button on the about page will be hidden. The
"end-of-the-line" message will appear there, alongside the icon normally used
for failed updates. The startup infobar text will change at that point as
well.

No observable changes for non-branded Chromium builds (since they're not
receiving updates through this mechanism) or for users with 64-bit-capable
systems (because they're not being obsoleted).

Give QuickTime the plugin stream data in writeable memory as it modifies it.

This broke after switching the fetching of plugin stream data to the plugin process because now the data from ResourceDispatcher is passed directly to the plugin and it's read-only.
