643876fb77 extmod/vfs_fat: Allow to compile with MICROPY_VFS_FAT disabled. 
Some ports may want to compile with generic MICROPY_VFS support but without
the VfsFat class.  This patch allows such a thing.

ae8d867586 py: Add iter_buf to getiter type method. 
Allows to iterate over the following without allocating on the heap:
- tuple
- list
- string, bytes
- bytearray, array
- dict (not dict.keys, dict.values, dict.items)
- set, frozenset

Allows to call the following without heap memory:
- all, any, min, max, sum

TODO: still need to allocate stack memory in bytecode for iter_buf.

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.

0bd61d23b9 extmod/vfs_fat: Remove MICROPY_FATFS_OO config option. 
Everyone should now be using the new ooFatFs library.  The old one is no
longer supported and will be removed.

f5f4cdae89 extmod/vfs_fat: Rework so it can optionally use OO version of FatFS. 
If MICROPY_VFS_FAT is enabled by a port then the port must switch to using
MICROPY_FATFS_OO.  Otherwise a port can continue to use the FatFs code
without any changes.

59a1201da9 all: Remove readall() method, which is equivalent to read() w/o args. 
Its addition was due to an early exploration on how to add CPython-like
stream interface. It's clear that it's not needed and just takes up
bytes in all ports.

5694201930 extmod/vfs_fat_file: Make file.close() a no-op if file already closed. 
As per CPython semantics.  In particular, file.__del__() should not raise
an exception if the file is already closed.

07209f8592 all: Rename mp_obj_type_t::stream_p to protocol. 
It's now used for more than just stream protocol (e.g. pin protocol), so
don't use false names.
