ebiten/audio/player_cbackend.go
Hajime Hoshi 1799ed0b28 add a build tag 'ebitencbackend' and internal/cbackend
This enables to create a C archive with Ebiten without an actual driver
implementation. This enables Ebiten work on a platform Go doesn't support.
See also Hitsumabushi project: github.com/hajimehoshi/hitsumabushi.

The backend C API is not stable and might change later. Then, the build
tag 'ebitencbackend' is not documented on purpose.

Closes #1900
