Translate well known filesystem-like wilcards ('?' for single character and '*' for 0 or more) to:

  a) Suitable SQL pattern (with '_' and '%' instead) for 'like' and 'ilike' comparsion.
  b) Suitable regular expression.

In both cases whithout breaking anything. That is, exitent meaningful ('%', and '_' for DB
and '.', '+', '[', etc... for regular expressions) should be properly escaped.
