ii: Update to 1.8

1.8 (2018-02-04):
    - prevent nick collisions by only setting the nick after the server
      accepted it and print a message about change to server log.
    - remove query.sh.
    - add OpenBSD pledge(2) support.
    - fix QUIT message string.
    - raw IRC output to stdout.
    - add quit command (/q [string]).
    - write timestamp in outfile as UNIX timestamp (UTC+0).
    - server host (-s) doesn't default to irc.freenode and is now required.
    - add option (-u) to connect directly to a UNIX domain socket, this
      is useful for tunneling connections.
    - remove "in" file when leaving a channel (enabled commented code).
    - remove "in" files on exit.
    - use IRC_MAX (512), instead of PIPE_BUF (4096) on most systems.
      PIPE_BUF is guaranteed to be atleast 512 bytes for atomic operations.
    - Makefile: always be verbose.
    - use C99 and -D_DEFAULT_SOURCE
    - remove obsolete gethostbyname, use getaddrinfo.
    - IPV6 support.
    - timeout now uses separate exit statuscode 2.
    - cleanup:
        - use arg.h for command-line option parsing.
        - use sbase util functions (estrtol, eprintf).
        - use and import OpenBSD strlcpy().
        - man page typos.
    - style:
        - linewrap to 79 characters.
        - coding style fixes.
        - non-roman numerals for LICENSE period.

Add SHA512 digests for distfiles for chat category

Problems found with existing distfiles:
	distfiles/icb-5.0.9.tar.gz
	distfiles/icb.2.1.4.tar.Z
	distfiles/zenicb-19981202.tar.gz
No changes made to these /distinfo files.

Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden).  All existing
SHA1 digests retained for now as an audit trail.

Log message:
Import ii-1.7 as chat/ii.

ii is a minimalist FIFO and filesystem-based IRC client. It creates an irc
directory tree with server, channel and nick name directories.
In every directory a FIFO in file and a normal out file is created.

The in file is used to communicate with the servers and the out files
contain the server messages. For every channel and every nick name there
are related in and out files created. This allows IRC communication from
command line and adheres to the Unix philosophy.
