3ds: 3ds port sources. Second set of two.

Browse source 
This commit adds new files written exclusively for the 3ds port.

Additional comments:

1. Plugins works, but will be enabled in future commits.
2. The port has only been tested on the New 3DS.
3. Not all features of rockbox have been tested so there may be bugs or non-functional features.
4. There is a known issue where a random crash can occur when exiting the app.
