Change subject: add osmo_{escape,quote}_str_buf2() for OSMO_STRBUF_APPEND() use
......................................................................


Patch Set 1:

> _buf changes

We've recently added the OSMO_STRBUF_APPEND() macro, which works well with function signatures like snprintf(), i.e. first arguments are buf and len, and it returns an *int* len of characters that would have been written.

The _buf functions generally return a char* to be useful for printf formats. They can't be used with OSMO_STRBUF_APPEND() directly because that requires the int return val. However, they *can* be used with OSMO_STRBUF_PRINTF():

  OSMO_STRBUF_PRINTF(sb, "%s", osmo_gsm48_classmark_a5_name_buf(...));

So, this patch should probably not bother to introduce _buf functions that adhere to the snprintf() signature. It is fine to return a char* and use those with OSMO_STRBUF_PRINTF().
