Modified for use w/ reicast per-game configuration
Since read_params, packet_cmd, read_buff, pio_buff, ata_cmd, cdda and
ByteCount have not been declared static, they are visible in other
translation units. Since their structs are anonymous, their types have
internal linkage only. Thus, accessing them in other translations units
is impossible anyway.
By declaring them static, we're giving it internal linkage so that
neither the type nor the variable are visible in other translation
units.
Here are the errors:

Notes:
Disc swapping should work on .gdi files (probably .chd files too).
Swapping with .cdi files is not currently supported because we currently create inaccurate TOC for them.
Only x86/Windows has a disc swap handler right now (ie: you can't swap on Android).
