This will update pjnath-test for IPv6 support.

• Stun sock test : IPv4 and IPv6 test
• Turn sock test : IPv4 and IPv6 test
• ICE test : IPv4, IPv6, IPv4+IPv6 and mixed test (IPv4 controller v IPv6 controlled)

We recommend libyuv which provides video scaling and conversion method. However, currently we only support libyuv as a stand alone project, with these drawbacks:

• Following the recommended steps to build the library, it is required to also download chromium project which is large in size (approximately 10GB).
• Changes on the libyuv project might break the existing build configuration.

This ticket will add libyuv to the third party folder, use a specific version and include only the necessary source.

Below is the steps to build and use libyuv:

For GNU targets

1. By default, libyuv will always be built automatically. This automatic build can be disabled via configure script param --disable-libyuv or --disable-video.
2. if you want to use external libyuv, specify --with-external-libyuv and set header/library search paths via CFLAGS and LDFLAGS environment variables.

Additional step for iOS targets

1. Add third-party/lib/libyuv-[TARGET].a to application project in XCode.

Known issues

1. GCC 4.2 to 4.7 have a known issue using vectors with const, sample build error message:

   ../../yuv/source/row_common.cc: In function 'void libyuv::YuvPixel(uint8, uint8, uint8, uint8*, uint8*, uint8*, const libyuv::YuvConstants*)':
   ../../yuv/source/row_common.cc:1256: error: invalid types 'const signed char __vector__[int]' for array subscript
   ../../yuv/source/row_common.cc:1257: error: invalid types 'const signed char __vector__[int]' for array subscript
   

   Solution: use GCC 4.8 or newer, or if you don't need video feature, just disable libyuv (i.e: using configure script param --disable-libyuv or --disable-video).

For Visual Studio

1. libyuv will always be built automatically.
2. To enable libyuv, add this to your config_site.h:

   #define PJMEDIA_HAS_LIBYUV		1
