docs: rewrite resources documentation
Huge overhaul. Includes all new dev guides about how resources are used
on Android and how to provide alternatives, including how to handle
runtime configuration changes (restarts). Plus all new reference
docs for all the resource types (drawables, strings, menus, etc.).

Merge commit '479a49f74f77855825ba69b105c065422c24246a'
* commit '479a49f74f77855825ba69b105c065422c24246a':
sdk doc change for esr: Add "resources" tab content. Fix links pointing to the old locations. Change Android.mk to output samples files to resources/samples. Misc other fixes.
I haven't touched instances of "behaviour", "dequeue", "removeable",
"resizeable", or "removeable" because all are accepted variant spellings
and I don't know what the policy is on such things.
