[CRYPTO] all: Pass tfm instead of ctx to algorithms
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.
