Add the MODULE_ALIAS for the cra_driver_name of the different ciphers to
allow an automated loading if a driver name is used.

available sha512 transforms
Restructure the x86 sha512 glue code so we will expose sha512 transforms
based on SSSE3, AVX or AVX2 as separate individual drivers when cpu
provides support. This will make it easy for alternative algorithms to
be used if desired and makes the code cleaner and easier to maintain.

There are two concepts that have some confusing naming:
1. Extended State Component numbers (currently called
XFEATURE_BIT_*)
2. Extended State Component masks (currently called XSTATE_*)
The numbers are (currently) from 0-9. State component 3 is the
bounds registers for MPX, for instance.
But when we want to enable "state component 3", we go set a bit
in XCR0. The bit we set is 1<<3. We can check to see if a
state component feature is enabled by looking at its bit.
The current 'xfeature_bit's are at best xfeature bit _numbers_.
Calling them bits is at best inconsistent with ending the enum
list with 'XFEATURES_NR_MAX'.
This patch renames the enum to be 'xfeature'. These also
happen to be what the Intel documentation calls a "state
component".
We also want to differentiate these from the "XSTATE_*" macros.
The "XSTATE_*" macros are a mask, and we rename them to match.
These macros are reasonably widely used so this patch is a
wee bit big, but this really is just a rename.
The only non-mechanical part of this is the
s/XSTATE_EXTEND_MASK/XFEATURE_MASK_EXTEND/
We need a better name for it, but that's another patch.

xfeature checks
Use the new 'cpu_has_xfeatures()' function to query AVX CPU support.
This has the following advantages to the driver:
- Decouples the driver from FPU internals: it's now only using <asm/fpu/api.h>.
- Removes detection complexity from the driver, no more raw XGETBV instruction
- Shrinks the code a bit.
- Standardizes feature name error message printouts across drivers
There are also advantages to the x86 FPU code: once all drivers
are decoupled from internals we can move them out of common
headers and we'll also be able to remove xcr.h.

'xsave' is an x86 instruction name to most people - but xsave.h is
about a lot more than just the XSAVE instruction: it includes
definitions and support, both internal and external, related to
xstate and xfeatures support.
As a first step in cleaning up the various xstate uses rename this
header to 'fpu/xstate.h' to better reflect what this header file
is about.

We already have fpu/types.h, move i387.h to fpu/api.h.
The file name has become a misnomer anyway: it offers generic FPU APIs,
but is not limited to i387 functionality.

This removes all the boilerplate from the existing implementation,
and replaces it with calls into the base layer. It also changes the
prototypes of the core asm functions to be compatible with the base
prototype
void (sha512_block_fn)(struct sha256_state *sst, u8 const *src, int blocks)
so that they can be passed to the base layer directly.

Memset on a local variable may be removed when it is called just before the
variable goes out of scope. Using memzero_explicit defeats this
optimization. A simplified version of the semantic patch that makes this
change is as follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
identifier x;
type T;
@@
{
... when any
T x[...];
... when any
when exists
- memset
+ memzero_explicit
(x,
-0,
...)
... when != x
when strict
}
// </smpl>

This prefixes all crypto module loading with "crypto-" so we never run
the risk of exposing module auto-loading to userspace via a crypto API,
as demonstrated by Mathias Krause:

Add sha384 implementation to sha512_ssse3 module.
This also fixes sha512_ssse3 module autoloading issue when 'sha384' is used
before 'sha512'. Previously in such case, just sha512_generic was loaded and
not sha512_ssse3 (since it did not provide sha384). Now if 'sha512' was used
after 'sha384' usage, sha512_ssse3 would remain unloaded. For example, this
happens with tcrypt testing module since it tests 'sha384' before 'sha512'.
