This change is to migrate the getaddrinfo tests defined in the old file system/extras/tests/bionic/libc/common/test_getaddrinfo.c to the new place bionic/tests/netdb_test.cpp. The test here is more thorough, and catches a bug in getservbyname(3) that was breaking getaddrinfo(3)'s ability to look up services by name without a hint that would cause it to ask for a specific protocol.
