Log message:
Set INSTALLATION_DIRS properly. Fixes installation on at least SunOS.

Log message:
Remove example rc.d scripts from PLISTs.

These are now handled dynamically if INIT_SYSTEM is set to "rc.d", or
ignored otherwise.

Log message:
Drop superfluous PKG_DESTDIR_SUPPORT, "user-destdir" is default these days.

Log message:
Rename internal "getline" to unbreak build on NetBSD.
Support staged installation.

Log message:
Convert @exec/@unexec to @pkgdir or drop it.

Log message:
Fix a typo in a comment.

Log message:
Convert packages that test and use USE_INET6 to use the options framework
and to support the "inet6" option instead.

Remaining usage of USE_INET6 was solely for the benefit of the scripts
that generate the README.html files.  Replace:

	BUILD_DEFS+=	USE_INET6
with
	BUILD_DEFS+=	IPV6_READY

and teach the README-generation tools to look for that instead.

This nukes USE_INET6 from pkgsrc proper.  We leave a tiny bit of code
to continue to support USE_INET6 for pkgsrc-wip until it has been nuked
from there as well.
