mplayer: fix ARM floating point related build failures

This commit fixes two separate, but related build failures:

 * A failure that was happening when the ARM CPU supports NEON,
   floating point is enabled, but not with the NEON FPU. In this case,
   the NEON ARM assembly is rejected by the assembler, with messages
   like "Error: selected FPU does not support instruction -- `vmul.f32
   q0,q0,q1'". To fix this, we pass -mfpu=neon when we build mplayer
   with NEON support.

   Fixes:

 * A failure that was happening when the ARM CPU supports NEON, but
   the configuration is anyway using soft-float. In this case, mplayer
   attempts to compile NEON floating point instructions, but this
   obviously fail in a soft-float context, with errors such as 'Error:
   selected processor does not support ARM mode `vmov d0,r7,r8''. To
   fix this, we do not allow NEON to be enabled when we are in a
   soft-float configuration.

libcap: add menu entry to install tools.

libcap provides a set of tools to manipulate capabilities, among which
`setcap(8)` and `getcap(8)`. A new menu entry has been added to install them.

[Thomas: mark the new option as requiring MMU support, because the
programs use fork(), and completely rework the new .mk logic as it
wasn't taking into account the BR2_PREFER_STATIC_LIB case.]

smack: new package.

SMACK stands for Simplified Mandatory Access Control Kernel. It is a Linux
Security Module which provides a Mandatory Access Control mechanism,
like SELinux, but aiming towards simplicity.

This package provides the tools to load/unload the policy from the
kernel as well as a library allowing applications to interact with
SMACK. The proper kernel options are also set.

[Thomas:
- fixed license to be LGPLv2.1 instead of LGPLv2.1+. Even though the
  debian/copyright file has the "or later" indication, none of the .c
  source files carry it, so I suppose LGPLv2.1 is more correct.
- added !BR2_PREFER_STATIC_LIB dependency.
- added dependency on host-pkgconf, since Smack configure.ac uses
  PKG_CHECK_MODULES.]

system: add ability to pass additional users tables.

A new entry has been added to the "System Configuration" menu to allow
the user to set the location of additional user tables (besides the ones
defined in packages).

A user table is a text file, formatted using the mkusers syntax, which
describes the users on the target system, with their UID/GID, home
directory, password, etc.

The target root file system will be populated according the content of
these files.

mysql: disable maintainer mode

The maintainer mode enables additional gcc warnings, including
-Werror, which causes build failures with certain toolchains. Since we
generally don't enable -Werror in Buildroot, it doesn't make much
sense to have it enabled for MySQL.

sunxi-mali: add missing GLchar definitions.

The GLES and GLES2 header files provided by sunxi-mali do not define the
type "GLchar" and use "char" instead in the prototype of some functions.

In order to have some applications build (like cairo), a new patch has
been added to define the missing type.

This issue has been reported upstream some time ago, but the pull
request has not been merged yet.
(See https://github.com/linux-sunxi/sunxi-mali/pull/8).

Fixes http://autobuild.buildroot.net/results/2cb/2cb13a5bb92dabed219d49f49f0b9a2dfe65a0ca/.

qt: add an option to install the test module

When building Qt in a minimal configuration, a couple of Qt modules
(QtNetwork, QtSql, QtTest and QtXml) are built in addition to QtCore,
so they are installed in the sysroot but they are not copied into the
target tree.

Among these modules that could be built but optionally installed, only
QtTest had no option to allow being installed in the target fs.

Thus, programs linking against QtTest would successfully build, but
would miserably fail at runtime due to this missing dependency.

So far, the only package triggering this issue is OpenCV (the highgui
module built with Qt support).

A followup patch will add this missing dependency in OpenCV using this
new option.

opencv: fix qt selection when highgui is enable

So, update the OpenCV Config.in with the missing Qt module selection.
