udf: Remove struct ustr as non-needed intermediate storage

Although 'struct ustr' tries to structurize the data by combining
the string and its length, it doesn't actually make much benefit,
since it saves only one parameter, but introduces an extra copying
of the whole buffer, serving as an intermediate storage. It looks
quite inefficient and not actually needed.

This commit gets rid of the struct ustr by changing the parameters
of some functions appropriately.

Also, it removes using 'dstring' type, since it doesn't make much
sense too.

Just using the occasion, add a 'const' qualifier to udf_get_filename
to make consistent parameters sets.
