* john/erts/fix-port-leak/OTP-13939/ERL-193:
  Add a testcase for OTP-13939/ERL-193
  Mark socket disconnected on tcp_send_or_shutdown_error

# Conflicts:
#	lib/kernel/test/gen_tcp_misc_SUITE.erl

This allows the use of ~ts/~tp/~tw in calls to error_logger:format/2,
error_logger:error_msg/2 and error_logger:info_msg/2.

This reverts commit 5d9bb41114544c9205a8b8f26642bad8231e8d4e.

* raimo/kernel/inet_ntoa_1-IPv6-lowercase/ERIERL-20/ERL-429/OTP-13006:
  Accept IPv6 address %suffixes when parsing
  Adjust inet:ntoa/1 to RFC5952, but not deeper
  Update inet:ntoa according to modern RFCs

This only implements decimal suffixes, and furthermore only with
a leading "0".  A complete implementation would probably allow one
and probably two digit suffixes without.

But what primarily is missing is translating interface names to
and from interface indexes.

This also only implements the parsing, and uses the FreeBSD trick of
squeezing in the Scope Id in the second 16-bit word of the fe80::/64
or ff02:/64 address prefix.  But inet_drv is not prepared to handle
this word, so it might only work on FreeBSD, not being supported even
there...  So inet_drv needs to handle this too.
