The browser processes gets the real process ids, so they look correct in the task manager. When it asks the zygote to reap a process, we use the process ids internal to the sandbox.
While we are at it, reap the sandbox process after it clones the zygote and figure out zygote's actual process id. Save the actual process id rather than that of the sandbox.
Original review: http://codereview.chromium.org/262020
This is try 2 - initialize the sandbox host and zygote for InProcessBrowserTest.

BUG=20012, 20714, 23072
TEST=Process IDs for renderers should be correct in the task manager and you should be able to use the end process button to kill them.

The localtime (and localtime_r) functions try to access /etc/localtime
in the filesystem. For sandboxed renderers, this fails, the the
functions default to a UTC timezone.
These functions are called from within WebCore and V8 and there's no
clean way to patch the source code in place to do a hairpin turn and
manage an IPC. Additionally, we cannot overwrite the calls with the
usual symbol resolution procedures since the same chrome binary must
serve as both the unsandboxed browser and sandboxed renderer.
Thus we patch the GOT at runtime if we find, in the zygote process,
that we are sandboxed.
BUG=16800
TEST=Run javascript:alert(new Date().getTimezoneOffset()) in a sandboxed renderer. The resulting timezone offset (in minutes) should be correct for the local timezone.

This is hopefully the last step before our renderers can run cleanly
in a chroot.
WebKit needs to be able to ask for the correct font to use in the case
that the current font doesn't include glyphs for certain code points.
Currently we make a fontconfig call in our WebKit port to handle this.
This patch changes this so that the call is sent our via
ChromiumBridge. Since we are at ChromiumBridge, we could make a sync
IPC to the browser. However, fontconfig is a single threaded library
and we are already using it on the UI thread in the browser, so the
sync IPC would have to terminate on the UI thread. Even if this
doesn't deadlock, it causes huge spikes in latency.
So, instead, we send the IPC to the sandbox host process which is
already setup to handle fontconfig requests from Skia. See:
