Neels Hofmeyr 04eb56f146 add osmo_quote_str(),osmo_quote_str_buf() and test ... Rationale: with osmo_escape_str(), you get the escaped contents of the string, but not so graceful handling of NULL strings. The caller needs to quote it, and for NULL strings not quote it. osmo_quote_str() is like osmo_escape_str() but always quotes a non-NULL string, and for a NULL string returns a literal NULL, i.e. it should (tm) give the exact C representation of a string. That's useful in testing, to show exactly what char* situation we have, without jumping through hoops like if (str) printf("\"%s\"", osmo_escape_str(str, -1)); else printf("NULL"); Copy the unit test for osmo_escape_str() and adjust. To indicate that the double quotes are returned by osmo_quote_str(), use single quotes in the test printf()s. I considered allowing to pick the quoting characters by further arguments, but that complicates things: we'd need to escape the quoting characters. Just hardcode double quotes like C.
