e09b20aee85f1dfd8c18c3d8581ac875d939ba70 06-Jul-2014 Sreeram Ramachandran <sreeram@google.com> 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.

This is a cosmetic change, i.e., there's no change in functionality.

This is the poor man's RTTI. It turns out that maintaining separate lists (or
maps) of the different types of networks gets burdensome pretty quickly
(especially in an upcoming CL where we add functions like
canUserSelectNetwork()).

f4f6c8de3f091be4b91a5a9d7f14e8882ec6d502 23-Jun-2014 Sreeram Ramachandran <sreeram@google.com> 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.
