ParcelFileDescriptor rely on garbage collection to close handler.
When there is any error during starting clat or quick on/off
IPv6 only network, the file descriptor may not be able to be closed
before next clatStart is called. This may be problematic. For
example, the same v4- tun interface has not closed yet and clatStart
has been called again.

This is a startup commit. Starting clatd needs to prepare local

clat read/write sockets. These will be implemented from this

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

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.
