mei: Move uuid.h to the MEI namespace There is only a single user of the UUID uAPI, let's make it part of that user. The way it's done is to prevent compilation time breakage for the user space that does #include <linux/uuid.h> In the future MEI user space tools can switch over to use mei_uuid.h.

uuid: Provide a GUID generator for raw buffer 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.

uuid: Add inline helpers to import / export UUIDs Sometimes we may need to import UUID from or export to the raw buffer, which is provided outside of kernel and can't be declared as UUID type. With current API this operation will require an explicit casting to one of UUID types and length, that is always a constant derived as sizeof the certain UUID type. Provide a helpful set of inline helpers to minimize developer's effort in the cases when raw buffers are involved.

uuid: rename uuid types 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.

uuid,afs: move struct uuid_v1 back into afs This essentially is a partial revert of commit ff548773 ("afs: Move UUID struct to linux/uuid.h") and moves struct uuid_v1 back into fs/afs as struct afs_uuid. It however keeps it as big endian structure so that we can use the normal uuid generation helpers when casting to/from struct afs_uuid. The V1 uuid intrepretation in struct form isn't really useful to the rest of the kernel, and not really compatible to it either, so move it back to AFS instead of polluting the global uuid.h.

Unified UUID/GUID definition 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.
