vaExportSurfaceHandle support request (makes Firefox work)

[GBeauregard]

According to Mozilla after i recently inquired and #11 (comment) the only reason this doesn't work with Firefox now that nvidia-drivers has added DMABUF support is the lack of this wrapper supporting a "vaExportSurfaceHandle" method.

Implementing "vaExportSurfaceHandle" here would enable accelerated video decoding in Firefox for nvidia users.
