Subject: [PATCH] CLEANUP: patterns: get rid of pattern_data_setstring()

This function was only used to call chunk_init_len() from another chunk,
which in the end consists in simply assigning the source chunk to the
destination chunk. Let's remove this indirection to make the code clearer.
Anyway it was the only place such a function was used.
