Drop support for Linux Fedora 10 (ports part)
games/dsnake only worked with linux-f10

Should fix INDEX

- 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.

Cleanup plist

Update CentOS base to 6.5, add userland ports

The Fedora 10 infrastructure ports have been in use since June 2009 and, while
having served a great deed, have become unsupported upstream and hence affected
by unfixed security vulnerabilities. In addition to that, many recent Linux
binaries need newer libc / stdlibc++ versions.

This commit adds the linux-c6- userland as drop-in replacement for the -f10
infrastructure, as well as upgrading the linux_base-c6 port to CentOS 6.5.

If you want to switch to linux-c6 ports, please define at /etc/make.conf:

    OVERRIDE_LINUX_BASE_PORT=c6
    OVERRIDE_LINUX_NONBASE_PORTS=c6

Add staging support for linux-f10-* ports maintained by emulation@
(category multimedia).

Add NO_STAGE all over the place in preparation for the staging support (cat:
multimedia)

Remove expiration date, a false positive in my last commit.

Noticed by:     bsam

Set the expiration date for all ports which depend upon linux_base-fc4 to
the EoL of the last 7.x release. The 7.x branch is the only supported
FreeBSD version not yet at his EoL which needs a linux 2.4 based linuxulator
environment (linux_base-f10 doesn't work there).

I didn't bump the portrevision, this is mostly done as a hint for ports
committers to tell them that at least the emulation@-owned ports need
to stay until then (even the forbidden ones). The dependent ports need to
go at the same time, but are free to be deleted before.

Discussed with: bsam

Fix the "Whom" header: emulation -> bsam.

libv4l is a collection of libraries which adds a thin abstraction layer on
top of video4linux2 devices. The purpose of this (thin) layer is to make it
easy for application writers to support a wide variety of devices without
having to write separate code for different devices in the same class. libv4l
consists of 3 different libraries: libv4lconvert, libv4l1 and libv4l2.

libv4lconvert offers functions to convert from any (known) pixel-format
to V4l2_PIX_FMT_BGR24 or V4l2_PIX_FMT_YUV420.

libv4l1 offers the (deprecated) v4l1 API on top of v4l2 devices, independent
of the drivers for those devices supporting v4l1 compatibility (which many
v4l2 drivers do not).

libv4l2 offers the v4l2 API on top of v4l2 devices, while adding for the
application transparent libv4lconvert conversion where necessary.
