Deprecate ports broken for more than 6 months

Mark a few ports BROKEN (unfetchable)

- Replace Mk/bsd.linux-apps.mk and Mk/bsd.linux-rpm.mk with
  Mk/Uses/linux.mk.
- Replace USE_LINUX=yes with USES+=linux and USE_LINUX=(.*) with
  USES+=linux:\1 in all ports.
- Replace USE_LINUX_APPS with USE_LINUX in all ports.
- Use INSTALL_SCRIPT instead of INSTALL_PROGRAM to install scripts in some
  ports.
- When USE_LINUX_RPM is defined, simplify the way DISTFILES and EXTRACT_ONLY
  are defined.
- Remove BRANDELF_DIRS and BRANDELF_FILES handling.  In the very rare cases
  that it is still necessary ports can run ${BRANDELF} from post-patch.
- Remove AUTOMATIC_PLIST handling.  Only one port used it.
- Fix Linux MASTER_SITES.
- Replace OVERRIDE_LINUX_BASE_PORT and OVERRIDE_LINUX_NONBASE_PORTS with
  default versions framework.

Mega-patch to cleanup the ports infrastructure regarding our linux bits:
  - USE_LINUX now implies NO_FILTER_SHLIBS=yes. It also doesn't use FreeBSD
    tools to strip binaries anymore, so it's not neccesary anymore to override
    STRIP and STRIP_CMD.
  - USE_LINUX_PREFIX implies NO_MTREE now.
  - In the USE_LINUX case, USE_XLIB now depends upon the linux X11 libraries
    instead upon the native FreeBSD libraries.
  - The variable LINUX_BASE_PORT contains a string which is suitable as an
    item in *_DEPENDS, so if a port BATCH_DEPENDS or FETCH_DEPENDS upon the
    default (or overriden) linux base, ${LINUX_BASE_PORT} should be used
    instead of a hardcoded reference.
  - Change all ports to comply to the "new world order".
  - The Ports Collection now allows to override the default linux_base port.
    Specify e.g. OVERRIDE_LINUX_BASE_PORT=rh-9 in /etc/make.conf to use
    ${PORTSDIR}/emulators/linux_base-rh-9 (the logic is to use

Respect the user's USE_LINUX setting.

Say hello to the linux mega patch, it consolidates our linux bits a
little bit and allows to proceed to a more recent linux_base from
a stable (read as: the major bugs should be ironed out or identified
and most linux ports build just fine) source.

It also allows to ship 4.11 with a working linuxolator (the EOLed
linux_base is marked forbidden because of a security hole).

This is a major update, please read UPDATING (and CHANGES if you
develop linux ports).

Changes:
 - change the default linux_base from v7 to v8
 - add a newer freetype to linux_base-8 for nicer fonts display [1]
 - don't let cpio use hardlinks in the linux_base-8 port to quiet some
