Ben Gras b80e3ac26b vm: new secondary cache 
Primary purpose of change: to support the mmap implementation, VM must
know both (a) about some block metadata for FS cache blocks, i.e. inode
numbers and inode offsets where applicable; and (b) know about *all*
cache blocks, i.e.  also of the FS primary caches and not just the
blocks that spill into the secondary one. This changes the interface and
VM data structures.

This change is only for the interface (libminixfs) and VM data
structures; the filesystem code is unmodified, so although the secondary
cache will be used as normal, blocks will not be annotated with inode
information until the FS is modified to provide this information. Until
it is modified, mmap of files will fail gracefully on such filesystems.

This is indicated to VFS/VM by returning ENOSYS for REQ_PEEK.
