This PR addresses a number of issues I've had with the qpage port for some time (rc.subr, ability to set some compile-time options) and also incorporates the patches from PR ports/123437. I filed this separate PR to avoid overloading the limited scope of ports/123437, but this patch encompasses that PR for ease of diffing/patching/committing. I hope this is not a problem. PR ports/123437 may be closed, and I'll follow up with the submitter.

Please also note that the patch removes all lines from files/qpage.sh.  The file should be removed/sent to the attic/... if that is not an automatic action on a zero-byte file.

Summary of changes
------------------
Makefile:
- Added rc.subr integration and removed references to etc/rc.d/qpage.sh

- Changed ${INSTALL_SCRIPT} to ${INSTALL_DATA} in post-install target


pkg-descr:
- Removed old maintainer e-mail address


pkg-plist:
- Removed etc/rc.d/qpage.sh entry (rc.subr integration)


files/:
- Removed qpage.sh and added qpage.in (rc.subr integration)
