In order to get counted by mts code coverage, this native test needs to
be run as part of mts.

Don't need anymore since ClatCoordinator uses common lib to access

bpf_connectivity_headers already pulls in bpf_headers,
which already pulls in bpf_syscall_wrappers.

for jni ClatdCoordinator.

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.

detect_mtu() is moved from ClatdController without behavior
change. The unique_fd for socket fd is replaced by primitive int
because libbase is not supported in mainline.

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.

Introduce the library libclat to implement clat functions for jni.
It is helpful for unit test.
makeChecksumNeutral() and its test are moved from ClatdController
without behavior change.
