tweak OSMO_STRBUF_APPEND(), add OSMO_STRBUF_APPEND_NOLEN()

In OSMO_STRBUF_APPEND, use local variable names that are less likely to shadow
other local variables: prefix with _sb_.

In OSMO_STRBUF_APPEND, add a check to add to .pos only if it is not NULL.

Add OSMO_STRBUF_APPEND_NOLEN(), which works for function signatures that don't
return a length. This is useful for any osmo_*_buf() string writing functions,
so that these write directly to the strbuf.
