FS#8226 - Enable audio menu for pacbox; enable audio for ipod 5g by putting emu on cop
This patch puts the pacbox emulator onto the cop, leaving the main cpu for audio codec. The COP behaviour is controller by a #define in pacbox.h
If PACBOX_ON_COP is defined, then all iram usage is also turned off, to prevent interference with audio thread.
Additionally, this patch adds an Audio menu (using the playback_control library), which is enabled for all PACBOX_ON_COP and GIGABEAT F-Series builds.
Patch from directly within the apps/plugins/pacbox directory.
