- Some random changes.. with no success - Grepping console buffer is not working * Cleanup the 'ds' and 'dp' commands - Implement 'dpa' to attach - Allow to list childrens of pid - Also list all attachable pids * Fix segfault by leaking.. needs some cleanup * Fix r_debug_reg_list (NULL) issue --HG-- rename : libr/cons/filter.c => libr/cons/grep.c
