Add full support for UIDs in VPNs. Major: + Implement the functions mentioned in http://go/android-multinetwork-routing correctly, including handling accept(), connect(), setNetworkForSocket() and protect() and supporting functions like canUserSelectNetwork(). + Eliminate the old code path of getting/setting UID ranges through SecondaryTableController (which is currently unused) and mUidMap. Minor: + Rename some methods/variables for clarity and consistency. + Moved some methods in .cpp files to match declaration order in the .h files. Bug: 15409918 Change-Id: Ic6ce3646c58cf645db0d9a53cbeefdd7ffafff93

Refactor: Encapsulate permissions and interfaces into a Network class. Currently, there's a lot of logic in NetworkController surrounding events such as interface addition/removal, network creation/destruction and default network change, because these events are interwined. For example, adding an interface means also adding a corresponding default network rule if the interface is being added to the current default network. When we introduce VPNs into this mix, things will get hairy real quick for all this logic in NetworkController. In this refactor, we introduce an abstract base class Network which supports adding and removing interfaces. The main concrete implementation of this is PhysicalNetwork, which allows setting permissions and "default network" state. Since we've moved network permissions into the above class, and user permissions into NetworkController, PermissionsController is unused and has been removed. Also fix a few bugs in RouteController: + Use uidEnd correctly. + Check for all error cases in inet_pton. + Check the return value of android_fork_execvp() correctly. + The "return cmd1() && cmd2()" pattern is wrong. Rewrite that code. Also (non-functional changes): + Remove instantiations of RouteController. It has static methods only. + Reorder some blocks in CommandListener so that the most frequent commands are checked first. + Remove unused paramError() and clearNetworkPreference(). + Change all return codes to int (negative errno) wherever applicable. + Add WARN_UNUSED_RESULT everywhere. + Cleanup some style in RouteController and NetworkController. + Use uid_t instead of unsigned for user IDs. + Add clearer log messages at the source of failures. + Add a check for when fwmark bits are set without corresponding mask bits.

Return negative errno (instead of positive) on failure. http://ag/489245 changed some return values from bools to errno values. However, in forthcoming CLs, @lorenzo uses the convention of negative errno to indicate failure. So, be consistent with that style. Change-Id: I3eac8f142c36a2e779cda289c07ee374c49e2f6b
