[pacsat-dev] Filesystem code

I have the filesystem code mostly ready. I changed the configuration to use 256 byte block. It's available in the filesystem branch.

So I will need a launchpad and a board with MRAM. My address is:

7406 Wheatfield Rd, Garland, TX 75044

Chris, you can test it if you like, too. I haven't written any tests for anything yet, that needs to be added.

There is code to automatically mount the filesystem on startup and format the filesystem if it detects corruption.

There are three new console commands: mount fs, unmount fs, and format fs.

The commands are the normal POSIX commands with "red_" prefixed, red_open(), red_close(), read_read(), etc.

I need to write a README about how this is all set up.
