Damien George 87283c1974 extmod/vfs: Implement mp_vfs_ilistdir(). 
uos.ilistdir() is the core function, returning an iterator that yields
3-tuples.  uos.listdir() is implemented in terms of ilistdir().

Damien George b697c89009 extmod: Merge old fsusermount.h header into vfs.h and vfs_fat.h. 
vfs.h is for generic VFS declarations, and vfs_fat.h is for VfsFat
specific things.

Damien George 6eafa54486 extmod/vfs: Expose lookup_path_raw as mp_vfs_lookup_path. 
It can be useful for low-level lookup of paths by ports.

Damien George 3f6b4e08e3 extmod/vfs: Expose mp_vfs_mount_t type. 
It should only be used for low-level things and with caution, for example
putting mounted VFS data in ROM or the static data section.

Damien George dcb9ea7215 extmod: Add generic VFS sub-system. 
This provides mp_vfs_XXX functions (eg mount, open, listdir) which are
agnostic to the underlying filesystem type, and just require an object with
the relevant filesystem-like methods (eg .mount, .open, .listidr) which can
then be mounted.

These mp_vfs_XXX functions would typically be used by a port to implement
the "uos" module, and mp_vfs_open would be the builtin open function.

This feature is controlled by MICROPY_VFS, disabled by default.
