Dominik Honnef 90cd27e4a0 x265: build a single shared library for all bit-depths
This builds the 10-bit and 12-bit versions of x265 as static
libraries, which then get linked into the 8-bit dynamic library and
executable. This causes x265 to default to 8-bit, but make 10- and
12-bit available to callers that use introspection, such as ffmpeg.

    $ x265 -V

    $ ffmpeg -h encoder=libx265
