Two utils to manipulate addresses in format "addr[:port]". I.e., network address (domain name or numeric), optionally followed by port number: * net_addr_str_find_port(), to return pointer to port number substring (or NULL if not present). * net_getaddrinfo_addr_str(), which is effectively getaddrinfo() wrapper taking a "addr[:port]" string as a parameter. The header file is named socketutils.h to emphasize that these utility functions are implemented on top of BSD Sockets API (and other POSIX/ANSI C functions), and thus portable to other POSIX systems (e.g., Linux), so can be used in apps testing POSIX compatibility. More utility functions (beyond address manipulation) can be added later. Signed-off-by: Paul Sokolovsky <paul.sokolovsky@linaro.org>
