utils: add helper wrapper for osmo_strlcpy()
Add wrapper for osmo_strlcpy() which uses sizeof() to automatically determine buffer's size and use it for GSMTAP logging. This is pretty common use case for osmo_strlcpy() so it's a good idea to save some typing by using generic define. Related: OS#2864 Change-Id: I03d0d3d32a8d572ad573d03c603e14cdc27a3f7b
