Gets some possible patterns that have to be matched against the user agent. With the given
user agent string, we can optimize the search for potential patterns:
- We check the first characters of the user agent (or better: a hash, generated from it)
- We compare the length of the pattern with the length of the user agent
(the pattern cannot be longer than the user agent!)
