Accelerated versions of crypto algorithms must carry a distinct driver name
and priority in order to distinguish themselves from their generic counter-
part.

Up until now algorithms have been happy to get a context pointer since
they know everything that's in the tfm already (e.g., alignment, block
size).
However, once we have parameterised algorithms, such information will
be specific to each tfm. So the algorithm API needs to be changed to
pass the tfm structure instead of the context pointer.
This patch is basically a text substitution. The only tricky bit is
the assembly routines that need to get the context pointer offset
through asm-offsets.h.

Various digest algorithms operate one block at a time and therefore
keep a temporary buffer of partial blocks. This buffer does not need
to be initialised since there is a counter which indicates what is and
isn't valid in it.
