MEDIUM: pattern: The function pattern_exec_match() returns "struct pattern" if the patten match.
Before this commit, the pattern_exec_match() function returns the
associate sample, the associate struct pattern or the associate struct
pattern_tree. This is complex to use, because we can check the type of
information returned.
Now the function return always a "struct pattern". If <fill> is not set,
only the value of the pointer can be used as boolean (NULL or other). If
<fill> is set, you can use the <smp> pointer and the pattern
information.
If information must be duplicated, it is stored in trash buffer.
Otherwise, the pattern can point on existing strings.
