Log message:
Update irssi to 0.8.13 (and bump pkgrevision irssi-icb).
Also contains security fix for CVE-2009-1959 (patch-ab).
Based on patch provided by Leonardo Taccari in PR 41785.

ChangeLog for 0.8.13
Features:

    * Reject some obviously invalid values in /set.
    * Add perl bindings for Window::get_history_lines
    * Use an io channel to write the config file.
    * Use memory slices instead of memory chunks for text buffer.
    * Remove methods to create/destroy TextBuffer and TextBufferView and low
      level api to add/remove lines, scripts should be fine using
      Window::print_after and TextBufferView::remove_line.
    * Add print_after method to Window perl object analogous to
      gui_printtext_after but which also expands formats and forces a full line.
    * Better mapping of signal parameters to Perl. All signals used in scripts
      now need to be registered with Irssi::signal_register.
    * Add public header with interfaces to manage statusbar items (bug #535)
    * Recode: assume utf-8 encoding for an ascii string in which no escape
      character occurs (bug #392).
    * Allow /BAN, /UNBAN, /KICBAN, /KNOCKOUT if channel is not synced.
      Requesting ban lists from an unsynced channel will ask them from the
      server, banning a user whose u@h irssi does not know will ban nick!*@* and
      only bans irssi knows about can be removed.
    * Allow storing multiple "other" prefixes such as +q and +a \ 
(original patch
      by JasonX)
    * Add /set autolog_ignore_targets for cherry-picking targets that shouldn't
      get logged.
    * Add support for 16 colors. Formats KBGCRMYW and mirc colors are now mapped
      to colors 8-15. fe-text translates colors 8-15 to bold/blink+0-7 if the
      terminal supports only 8 colors. If your theme uses one of the high color
      formats and you really want bold you can change %FMT<string> to %fmt%_%_,
      it will work fine in all irssi versions.
    * Better 005 PREFIX support (bug #580).
    * Display 407 numerics other than "duplicate channel".
    * Fix display of ratbox-style operspy whois.
    * Recode outgoing irc away messages (bug #412).
    * Recode outgoing irc quit messages.
    * Remove scrollback_levelclear_levels setting and add a 'level' option to
      'sb levelclear' to specify a comma separated list of levels.
    * Add perl __WARN__ handler for scripts (bug #427).
    * Add Irssi::command_parse_options function to parse options for a command.
    * Revert recode changes introduced in 0.8.12.
    * Add completion for /WINDOW SERVER.
    * Support for reading kicks/msgs from TARGMAX/MAXTARGETS 005 tokens.
    * Enhancements to the redirections code.
    * Support for RPL_WHOISACTUALLY (338 numeric) for both ratbox and ircu
      (bug #428).
    * -idle option of /notify is gone.
    * /layout save now makes window-channel bindings instantly effective
      (bug #35).
    * /ping without arguments does not send anymore a ctcp ping to a channel
      (bug #542).
    * Track IRC operator status of nicks a bit better.
    * new 'actlist_names' option to add active items names in 'act' statusbar
      item.
    * new 'word_completion_backward' command to scroll backwards in the
      completion list.
    * add 'list' option to /bind to print all the available commands.
    * show setter/time in +I lists
    * apply -usermode before -autosendcmd (bug #548).
    * reduce memory usage of the scrollback buffer and make the display in /sb
      status more accurate (higher).
    * fix data getting dropped when a lot is sent at a time (e.g. when attaching
      to irssi-proxy, bug #528).
    * introduce the type Irssi::Irc::Client and signals to communicate with
      proxy clients to allow for scripting parts of the irssi-proxy.
    * Add sb_search.pl, a script for /SCROLLBACK SEARCH

Bugfixes:

    * Fix /NOTIFY list when nick is seen joining (bug #642).
    * Include hostmask in 001 event sent by proxy (bug #650).
    * Be more power-friendly: don't run any always-on <1s timers (bug #641).
    * Don't get confused by a failed /JOIN -window (bug #644).
    * Properly initialize embedded Perl (PERL_SYS_INIT3).
    * Replace invalid utf-8 bytes with U+FFFD when drawing a line.
    * Properly unload the original script when using /script load to reload it.
      (bug #525, patch by Lukas Mai)
    * Clean up script loading in general:
       * Don't leak local variables to eval'd code.
       * Set filename/line number to get better error messages from perl.
       * Use three-arg open and lexical filehandles to avoid surprises.
       * Include error reason in message for unopenable scripts.
       * Don't wrap script code in sub handler { } - this avoids spurious
	 warnings and should at least allow __END__ to work properly. (Patch by
	 Lukas Mai)
    * Fix NETSPLIT_SERVER_REC in signals for Perl.
    * Remove buggy /SCROLLBACK redraw and /SET scrollback_save_formats.
    * Always preserve the active mainwindow when resizing.
    * Ignore DNS not found errors when considering reconnect.
    * Do not strip the comma in a mirc color if it is not followed by a digit
      (bug #250).
    * Fix building perl module with perl-5.10 (bug #630).
    * fix leak with $L expando.
    * fix possible crash with /script reset.
    * ignore exceptions take precedence over ignores in all cases.
    * honour -channels preference for ignore -replies (bug #227).
    * Fix mode display in whois with unreal (379 numeric) (bug #479).
    * Fix regressions that prevented external modules from building/working
      (bugs #537 #539).
    * Fix /set hilight_level not taking effect immediately (bug #598).
    * Fix bold, blinking and indentation in /LASTLOG and buf.pl.

Log message:
LIBTOOL_OVERRIDE generally doesn't need to be specified anymore... just
set OVERRIDE_DIRDEPTH to find any libtool scripts deeper in the WRKSRC
tree unless they're named something other than "libtool".

SHLIBTOOL_OVERRIDE generally doesn't need to be specified either -- just
define it to the empty list and shlibtool-override will look for libtool
scripts.
