Use heap to allocate PatternMatch to avoid potential stack overflow
When apt-cache search with many args (> 130) is given the allocation of PatternMatch on the stack may fail resulting in a segmentation fault. By using the heap the max size is much bigger and we also get a bad_alloc expection instead of a segfault (which we can catch *if* this ever becomes a pratical problem). No test for the crash as its not reproducable with the MALLOC_ settings in framework. Closes: 759612
