libc/inet/resolv.c:
Collapse __length_dotted into __length_question (the sole user of it). Make __length_question and __decode_answer static, they are used only once by only one function. Delete __decode_question, it is unused. All in all, four less .o files in libc.a. Document what __dns_lookup returns (length of the packet). Propagate packet len into __decode_answer, __length_question, __decode_dotted and check that we do not use data past the end of the packet. Rename some variables/parameters to better names (len -> packet_len, data -> packet etc). Add mini-doc how DNS packets look like. Style cleanup.
