f5d916a881 Kernel: Make sys$anon_create() fail if size == 0 
An empty anonymous file is useless since it cannot be resized anyway,
so let's not support creating it.

fb4993f067 Kernel: Add anonymous files, created with sys$anon_create() 
This patch adds a new AnonymousFile class which is a File backed by
an AnonymousVMObject that can only be mmap'ed and nothing else, really.

I'm hoping that this can become a replacement for shbufs. :^)
