As announced in commitbe28c14ac8("udplite: Print deprecation notice."), it's time to deprecate UDP-Lite. As a first step, let's drop support for IPv6 UDP-Lite sockets. We will remove the remaining dead code gradually. Along with the removal of udplite.c, most of the functions exposed via udp_impl.h are made static. The prototypes of udpv6_sendmsg() and udpv6_recvmsg() are moved to udp.h, but only udpv6_recvmsg() has INDIRECT_CALLABLE_DECLARE() because udpv6_sendmsg() is exported for rxrpc since commited472b0c87("rxrpc: Call udp_sendmsg() directly"). Also, udpv6_recvmsg() needs INDIRECT_CALLABLE_SCOPE for CONFIG_MITIGATION_RETPOLINE=n. Note that udplite.h is included temporarily for udplite_csum().
