Export the following functions to public:
- ubi_detach(): this is paired with ubi_part(). One may call this function
to completely clean up the ubi subsystem after using ubi_part().
- ubi_{create,find,remove}_vol: this is a set of functions for volume
management.
The original ubi_remove_vol is renamed to __ubi_remove_vol to allow the new
ubi_remove_vol() being used as a wrapper for __ubi_remove_vol() with volume
name.
Also, comments are added for all exported functions.

File name and volume name should be const as they will not be modified in
these functions.

Use void * to avoid explicit type casting as what ubi_volume_write has done

UBI block is an virtual device, that runs on top
of the MTD layer. The blocks are UBI volumes.
Intended to be used in combination with other MTD
drivers.
Despite the fact that it, like mtdblock abstraction,
it used with UCLASS_MTD, they can be used together
on the system without conflicting. For example,
using bcb command:
# Trying to load bcb via mtdblock:
$ bcb load mtd 0 mtd_partition_name
# Trying to load bcb via UBI block:
$ bcb load ubi 1 ubi_volume_name
User always must attach UBI layer (for example, using
ubi_part()) before using UBI block device.

At this point, we don't need to have <common.h> be included because of
properties in the header itself, it only includes other common header
files. We've also audited the code enough at this point that we can drop
<common.h> from being included in headers and rely on code to have the
correct inclusions themselves, or at least <common.h>.

We have some unused and undefined symbols to remove references to, so do
that. Move the final things that we do set (or need to keep unset) to
Kconfig instead.

cmd_ubifs_mount() function would be called directly instead of
involving whole command machinery for mounting ubifs in
generic firmware loader, so some checking codes need to be factored out
into cmd_ubifs_mount() without breaking original functionality design.

The UBI layer will disable much of its error reporting when it is
compiled into the linux kernel to avoid stopping boot. We want this
error reporting in U-Boot since we don't initialize the UBI layer until
it is used and want the error reporting.
We force this by telling the UBI layer we are building as a module.

"down_write_trylock" needs to return 1 instead of 0 for success.
Otherwise copying a block with a read error (e.g. bit-flip on read)
won't work correctly.

The U-Boot UBIFS implementation is largely a direct copy from the current
Linux version (2.6.29-rc6). As already done in the UBI version we have an
"abstraction layer" to redefine or remove some OS calls (e.g. mutex_lock()
...). This makes it possible to use the original Linux code with very
little changes. And by this we can better update to later Linux versions.
I removed some of the Linux features that are not used in the U-Boot
version (e.g. garbage-collection, write support).

This patch adds basic UBI (Unsorted Block Image) support to U-Boot.
It's based on the Linux UBI version and basically has a "OS"
translation wrapper that defines most Linux specific calls
(spin_lock() etc.) into no-ops. Some source code parts have been
uncommented by "#ifdef UBI_LINUX". This makes it easier to compare
this version with the Linux version and simplifies future UBI
ports/bug-fixes from the Linux version.
