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.Reviewed-by: Christoph Hellwig

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 *.Suggested-by: Christoph Hellwig

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.Signed-off-by: Christoph Hellwig

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.[andriy.shevchenko@linux.intel.com: fix typo]

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.Signed-off-by: Huang Ying
