add osmo_str_tolower() and _toupper() with test
We already have osmo_str2lower() and osmo_str2upper(), but these lack: * proper destination buffer bounds checking, * ability to call directly as printf() argument. Deprecate osmo_str2upper() and osmo_str2lower() because of missing bounds checking. Introduce osmo_str_tolower_buf(), osmo_str_toupper_buf() to provide bounds-safe conversion, also able to safely convert a buffer in-place. Introduce osmo_str_tolower(), osmo_str_toupper() that call the above _buf() equivalents using a static buffer[128] and returning the resulting string directly, convenient for direct printing. Possibly truncated but always safe. Add unit tests to utils_test.c. Replace all libosmocore uses of now deprecated osmo_str2lower(). Naming: the ctype.h API is called tolower() and toupper(), so just prepend 'osmo_str_' and don't separate 'to_lower'. Change-Id: Ib0ee1206b9f31d7ba25c31f8008119ac55440797
