Use stdio calls for file/directory interaction instead of fatfs (#95)

Browse Source 
<!--- Provide a general summary of your changes in the Title above -->

## Description
<!--- Describe your changes in detail -->
This PR changes most of the calls to the fatfs lib with the standard C
ones.
Additionally, there's couple of changes required to adapt to new
interface and several bug fixes.
As a bonus menu can now be run in ares emulator and on the iQue player,
adapting to the available storage options - DragonFS in the ROM and iQue
flash modules (bbfs).

## Motivation and Context
<!--- What does this sample do? What problem does it solve? -->
<!--- If it fixes/closes/resolves an open issue, please link to the
issue here -->
To make it easier to use storage medium other than SD cards on platforms
other than N64 with flashcart.

## How Has This Been Tested?
<!-- (if applicable) -->
<!--- Please describe in detail how you tested your sample/changes. -->
<!--- Include details of your testing environment, and the tests you ran
to -->
<!--- see how your change affects other areas of the code, etc. -->
