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.

fb3ae1784e extmod/vfs_fat: Rework to support new generic VFS sub-system. 
The VfsFat object can now be mounted by the generic VFS sub-system.

32a1138b9f extmod: Rename vfs_fat_file.h to vfs_fat.h. 
And move declaration of mp_fat_vfs_type to this file.

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.

b7df3e541a extmod/vfs_fat: Implement POSIX behaviour of rename, allow to overwrite. 
If the destination of os.rename() exists then it will be overwritten if it
is a file.  This is the POSIX behaviour, which is also the CPython
behaviour, and so we follow suit.

See issue #2598 for discussion.

d29ca28288 esp8266/modous: Add os.umount method to unmount a filesystem. 
This is an object-oriented approach, where uos is only a proxy for the
methods on the vfs object.  Some internals had to be exposed (the STATIC
keyword removed) for this to work.

Fixes #2338.

0a6f599cf2 extmod/vfs_fat: Implement rmdir() method. 
Shares the code with remove() method due to the same underlying f_unlink()
FatFs operation.

23067a1422 esp8266: Use RTC to set date & time stamps for files. 
The time stamp is taken from the RTC for all newly generated
or changed files. RTC must be maintained separately.
The dummy time stamp of Jan 1, 2000 is set in vfs.stat() for the
root directory, avoiding invalid time values.

ee009d713a extmod/vfs_fat.c: Add vfs.stat(). 
The call to stat() returns a 10 element tuple consistent to the os.stat()
call. At the moment, the only relevant information returned are file
type and file size.

7c004e794c extmod/vfs_fat*: Replace text error messages by POSIX error numbers. 
These changes are in line with similar changes in other modules, and
with standard Python interface.

19749db7bf extmod/vfs_fat: Add .remove() method. 
Based on stmhal implementation - rather small, so just duplicating.

e9be6a378c extmod/vfs_fat: Object-oriented encapsulation of FatFs VFS. 
This implements OO interface based on existing fsusermount code and with
minimal changes to it, to serve as a proof of concept of OO interface.

Examle of usage:

bdev = RAMFS(48)
uos.VfsFat.mkfs(bdev)
vfs = uos.VfsFat(bdev, "/ramdisk")
f = vfs.open("foo", "w")
f.write("hello!")
f.close()
