2aeb201c97 libbb: new option FEATURE_ETC_SERVICES: if off, /etc/services reads often avoided 
In practice, "wget http://host.com/" always uses port 80.
People explicitly set non-standard ports via options or parameters
("telnet 1.2.3.4 567" or "telnet 1.2.3.4 ftp") instead of modifying
/etc/services.

e2afae6303 sed: prevent overflow of length from bb_get_chunk_from_file 
This fragment did not work right:

                temp = bb_get_chunk_from_file(fp, &len);
                if (temp) {
                        /* len > 0 here, it's ok to do temp[len-1] */
                        char c = temp[len-1];

With "int len" _sign-extending_, temp[len-1] can refer to a wrong location
if len > 0x7fffffff.

518fb3ba19 udp_io, traceroute: Standardise IPv6 PKTINFO handling to be portable 
The current standard (RFC 3542) is for IPV6_RECVPKTINFO to be given to
setsockopt, and IPV6_PKTINFO to be used as the packet type. Previously,
RFC 2292 required IPV6_PKTINFO to be used for both, but RFC 3542
re-purposed IPV6_PKTINFO when given to setsockopt. The special
Linux-specific IPV6_2292PKTINFO has the same semantics as IPV6_PKTINFO
in RFC 2292, but was introduced at the same time as IPV6_RECVPKTINFO.

Therefore, if we have IPV6_RECVPKTINFO available, we can use the RFC
3542 style, and if not, we assume that only the RFC 2292 API is
available, using IPV6_PKTINFO for both.

0fd5dbba8f lineedit: improve multiline PS1 - redraw using last PS1 line. Closes 10381 
This patch only affects prompts with newlines.

We redraw the prompt [+ input] occasionally, e.g. during tab completion,
history browsing or search, etc, and we expect it to align with prior
redraws, such that the visible effect is that only the input changes.

With multi-line PS1, redraw always printed the prompt some lines below
the old one, which resulted in terminal scroll during every redraw.

Now we only redraw the last PS1 line, so vertical alignment is easier to
manage (we already calculated it using only the last line, but re-drew
all lines - that was the culprit), which fixes those extra scrolls.

Notes:
- We now use the full prompt for the initial draw, after clear-screen (^L),
  and after tab-completion choices are displayed. Everything else now
  redraws using the last/sole prompt line.

- During terminal resize we now only redraw the last[/sole] prompt line,
  which is arguably better because it's hard to do right (and we never did).

- Good side effect for reverse-i-search: its prompt now replaces only the
  last line of the original prompt - like other shells do.
