Log message:
Move scrollkeeper/omf.mk to rarian/omf.mk.
scrollkeeper is nowadays included in rarian, so the omf.mk file should
be there as well.
Adapt all references.

Log message:
move the install/deinstall templates from scrollkeeper to rarian
to reflect where the work is done
(call the backwards-compatible rarian version "install-scrollkeeper"
to leave room for a future non-compatibility version)

Log message:
remove the meat of scrollkeeper -- the library is not used by any pkg
anymore, and the users of .omf file install scripts are redirected to
"rarian" which provides compatible (to the caller) implementations

Log message:
rarian conflicts with scrollkeeper, so the reverse is also true.  Then,
add a conflicts line with rarian.

Log message:
Switch to use the scrollkeeper compatible wrappers which come with
the new "rarian" document manager. rarian (as configured currently)
can read .omf files directly, so the wrappers are basically no-ops.
Keep the "rarian" dependency anyway to avoid major reorganisations
in the future.

Log message:
Whitespace cleanup, courtesy of pkglint.
Patch provided by Sergey Svishchev in private mail.

Log message:
We use iconv, so add its buildlink3.mk. Also set ICONV=iconv in the
environment to avoid the build failing due to the 'extra smart' build
system in here taking "iconv" in intltool-merge.in and replacing it
with "/usr/pkg/bin/iconv"

Log message:
DESTDIR support.
