Elliott Hughes 95c6cd753f Stop using the __ANDROID_API_x__ constants.
Historically we've made a few mistakes where they haven't matched the
right number. And most non-Googlers are much more familiar with the
numbers, so it seems to make sense to rely more on them. Especially in
header files, which we actually expect real people to have to read from
time to time.
