// The network stack can be compiled using system_current (non-finalized) SDK, or finalized system_X
// SDK. There is also a variant that uses system_current SDK and runs in the system process
// (InProcessNetworkStack). The following structure is used to create the build rules:
//
// NetworkStackAndroidLibraryDefaults <-- common defaults for android libs
// / \
// +NetworkStackApiStableShims --> / \ <-- +NetworkStackApiCurrentShims
// +NetworkStackReleaseApiLevel / \ +NetworkStackDevApiLevel
// +jarjar apistub.api[latest].* / \ +module src/
// to apistub.* / \
// / \
// NetworkStackApiStableDependencies \
// / \ android libs w/ all code
// +module src/ --> / \ (also used in unit tests)
// / \ |
// NetworkStackApiStableLib NetworkStackApiCurrentLib <--*
// | |
// | <-- +NetworkStackAppDefaults --> |
// | (APK build params) |
// | |
// | <-- +NetworkStackReleaseApiLevel | <-- +NetworkStackDevApiLevel
// | |
// | |
// NetworkStackApiStable NetworkStack, InProcessNetworkStack, <-- APKs
// TestNetworkStack
