find_nth() will be inefficient on a trie. Since find_nth() is only used
internally and only for enumerating properties, we can add a foreach()
function to do this directly.

All the other property stuff is already here. Property setting was
only in libcutils previously to leverage a utility function / constant
or two.
Unfortunately in the process of fixing a race condition we would've
had to do break abstraction boundaries and put some libc-internal
details into libcutils so instead of that we'll just move this
into bionic.
Along with Iee1ca9b7, this now passes:
$ adb shell am instrument -w -e class android.os.SystemPropertiesTest \
com.android.frameworks.coretests.systemproperties/android.test.InstrumentationTestRunner
