Simple change that makes fs_seek and fs_tell return -ENOTSUP when
file system does not implement the seek/tell.

The documentation claims that Zephyr supports external file system
implementations, and there's no reason not to do so. Rework the API
to allow this.
Note that the file system type cannot legally be an enum anymore,
since we need to support file system types that don't have an
identifier assigned in that enum. Rely on the implicit conversion of
enum values to int to preserve backwards compatibility.

The fs_open has been extended with support for open flags.
Currently supported flags are:
FS_O_READ -- open for read
FS_O_WRITE -- open for write
FS_O_CREATE -- create file if it does not exist
FS_O_APPEND -- move to the end of file before each write
The FAT FS and LittleFS front-ends within the Zephyr has also been
modified to utilize the flags.

NFFS is removed as it has serious bugs (by design) which haven't
been resolved since extended range of time.
One of most serious issues bunch were described here:
https://github.com/apache/mynewt-nffs/issues/10
Since lack of support NFFS upsterem it doesn't make sense to keep
it in zephyr.

Existing file system implementations do not provide the special "."
(current) and ".." (parent) directory entries in the readdir results.
littlefs does.
Remove these entries in the abstraction layer. This simplifies code in
higher level consumers that aren't prepared to see them. Consumers like
FUSE that need them can put them back without having to worry about
conflicts.

move misc/dlist.h to sys/dlist.h and
create a shim for backward-compatibility.
No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.
