Remove <linux/hex.h> from <linux/kernel.h> and update all users/callers of
hex.h interfaces to directly #include <linux/hex.h> as part of the process
of putting kernel.h on a diet.
Removing hex.h from kernel.h means that 36K C source files don't have to
pay the price of parsing hex.h for the roughly 120 C source files that
need it.
This change has been build-tested with allmodconfig on most ARCHes. Also,
all users/callers of <linux/hex.h> in the entire source tree have been
updated if needed (if not already #included).

The prandom_bytes() function has been a deprecated inline wrapper around
get_random_bytes() for several releases now, and compiles down to the
exact same code. Replace the deprecated wrapper with a direct call to
the real function. This was done as a basic find and replace.

In some cases we would like to generate a GUID and export it. Though it
would require either casting to internal kernel types or an intermediate
buffer. Instead we may achieve this by supplying a pointer to raw buffer
and make a complimentary API to existing one for UUIDs.

Hoist the libnvdimm helper as an inline helper to linux/uuid.h
using an auxiliary const variable uuid_null in lib/uuid.c.
[hch: also add the guid variant. Both do the same but I'd like
to keep casts to a minimum]
The common helper uses the new abstract type uuid_t * instead of
u8 *.

Our "little endian" UUID really is a Wintel GUID, so rename it and its
helpers such (guid_t). The big endian UUID is the only true one, so
give it the name uuid_t. The uuid_le and uuid_be names are retained for
now, but will hopefully go away soon. The exception to that are the _cmp
helpers that will be replaced by better primitives ASAP and thus don't
get the new names.
Also the _to_bin helpers are named to match the better named uuid_parse
routine in userspace.
Also remove the existing typedef in XFS that's now been superceeded by
the generic type name.

There are new helpers in this patch:
uuid_is_valid checks if a UUID is valid
uuid_be_to_bin converts from string to binary (big endian)
uuid_le_to_bin converts from string to binary (little endian)
They will be used in future, i.e. in the following patches in the series.
This also moves the indices arrays to lib/uuid.c to be shared accross
modules.

There are many different UUID/GUID definitions in kernel, such as that
in EFI, many file systems, some drivers, etc. Every kernel components
need UUID/GUID has its own definition. This patch provides a unified
definition for UUID/GUID.
UUID is defined via typedef. This makes that UUID appears more like a
preliminary type, and makes the data type explicit (comparing with
implicit "u8 uuid[16]").
The binary representation of UUID/GUID can be little-endian (used by
EFI, etc) or big-endian (defined by RFC4122), so both is defined.
