BrowserContext outlives AwContents, it's equivalent to profiles in chrome, or
something like normal vs incognito mode that contains AwContents. From this, it
looks like AwBrowserContext can directly create and own this in the constructor.
(If it's a DEPS/layering violation, you can pass it in from
AwMainDelegate->AwContentBrowserClient->AwBrowerContext)

I just need some place in native/ to construct this. It is owned by
AwBrowserContext, and will only be created once. Is there a better place?

[boliu, 2013/01/03 08:48:35]

AwMainDelegate is in lib/ which can include native/. You can following the
existing AwWebContentsViewDelegate::Create example in 
AwMainDelegate::CreateContentBrowserClient to pass in a geo "factory function".
We might just consolidate to an actual factory interface after we get a bunch of
these.

Passed it in the ctor to AwContentBrowserClient.
