Jean-Christophe PLAGNIOL-VILLARD ab5b2c35e1 crypto: prepare to allow multiple digest driver
This will allow to have hw driver or asm optimised driver.

Use a priority level to determine which one to use at runtime.
The generic one will be 0.

Jean-Christophe PLAGNIOL-VILLARD e10cc0b333 digest: allow algo to specify their length at runtime
such as RSA as we load a DER key we will detect the key size
at runtime and so the algo length.

Jean-Christophe PLAGNIOL-VILLARD 7aeb9650b6 digest: add digest callback
Combination of @init and @update and @final. This function
effectively behaves as the entire chain of operations, @init,
@update and @final issued in sequence. This is added for hardware
which cannot do even the @finup, but can only do the whole
transformation in one run.

Jean-Christophe PLAGNIOL-VILLARD ec4f969971 digest: add verify callback
this will allow to compare a md with the original one

When calling this do not call final

For RSA_SIGN verification final does not exist only verify
as final will be for signing

Sascha Hauer e693622467 crypto: digest: Fix coding style
When declaring pointer data or a function that returns a pointer type, the
preferred use of '*' is adjacent to the data name or function name and not
adjacent to the type name.

Fix the remaining occurences in crypto/

Jean-Christophe PLAGNIOL-VILLARD 27b2336029 digest: make it multi-instance
Now you need to call digest_alloc and when you finish to use it digest_free.

We need this for upcomming aes encryption support and secure boot
as we will need multiple instance of the same digest.
