opkg: - replace package list parser by something that works with fixed buffers to avoid slurping the whole file into memory during parsing - fix a possible null pointer dereference in opkg_remove_cmd() - get rid of upgrade, it cannot upgrade single packages and kills the system in most cases - get rid of the flag operation, not needed - bump package revision
