Lindent script for Akaros

Some minor changes -- ts and i set to 8.
Should we dump the line length? Do we really care
about 80 columns? I know I don't.

Fixes up lindent

indent still messes up sometimes.  In some cases (like with weird printk
formatting), it can be fixed and won't cause the problem again.  In
others, like in sys_buster right after the #defines, it'll insist on
formatting in a weird manner.

Anyway, this is better than not formatting the code at all.
VFS dummy ops

To catch bugs when we calling ops on inodes/dentries unexpectedly.
Pipes (XCC)

Basic pipe functionality, using the old VFS.  Should be able to handle
multiple readers and writers, though I haven't tested that yet.

These pipes aren't rooted in the VFS yet, though we could extend them to
handle named pipes reasonably easily.

Rebuild your toolchain and any program that would use pipe (busybox).
