trust: make filesystem path construction flexible
To handle pathnames longer than the fixed length (previously 256), this adds a set of internal API functions around the gnutls_pathbuf_st struct, which enables to safely and efficiently construct pathnames. The new API initially uses the statically allocated buffer and starts allocating memory on heap only after the limit has reached.
