-kill the "iconv" option which doesn't serve any purpose anymore
-remove libmikmod from default options - it is buggy and possibly a
security risk (it is disabled in "configure" per default too)
-remove shout option - this didn't work anyway (can be fixed, but
I haven't used shout so far)
-enable ipv6 option - the comment on options.mk stating that IPv6
disables IPv4 doesn't seem to ve valid anymore
-fix some configure args which changed spelling over time
-fix a crash in case libmikmod is enabled and used
bump PKGREVISION
