* check return values of memory allocation and abort gracefully in out-of-memory situations * use sblist (linear dynamic array) instead of linked list - this removes one pointer per filter rule - removes need to manually allocate/free every single list item (instead block allocation is used) - simplifies code * remove storage of (unused) input rule - removes one char* pointer per filter rule - removes storage of the raw bytes of each filter rule * add line number to display on out-of-memory/invalid regex situation * replace duplicate filter_domain()/filter_host() code with a single function filter_run() - reduces code size and management effort with these improvements, >1 million regex rules can be loaded with 4 GB of RAM, whereas previously it crashed with about 950K. the list for testing was assembled from http://www.shallalist.de/Downloads/shallalist.tar.gz closes #20
