Introduce ClatCoordinator to replace netd/ClatdController.
This is a startup commit. Starting clatd needs to prepare local
464xlat ipv4 address, local 464xlat ipv6 address, tun interface,
clat read/write sockets. These will be implemented from this
and followup commits. This commit implements that prepare local
464xlat ipv4 address.

configure_packet_socket() is moved from ClatdController. Only change
the failure return value from errno to -errno. The remaining parts
are the same.
The test is modified from ClatdControllerTest::ConfigureIpv6Address.
Simply set socket filter to an interface and check that the packet
socket is bound to the interface. We can't check the socket filter
because there is no way to fetch it from the kernel.

isIpv4AddressFree() is moved from ClatdController without behavior
change.
selectIpv4Address() and its test are moved from ClatdController as well.
They have been refactored slightly for testing because function pointer
of isIpv4AddressFreeFunc is not a global variable anymore. We can't set
global function pointer to change selectIpv4Address() behavior for
testing. Instead isIpv4AddressFree is sent as an argument of function
pointer. For public caller, selectIpv4Address() has no behavior change.
For test caller, they can call an internal selectIpv4AddressInternal
(.., fn) to change isIpv4AddrFreeFn function pointer for testing.
