cipher/gost28147: generate optimized s-boxes from compact ones
* cipher/gost-s-box.c: New. Outputs optimized expanded representation of
s-boxes (4x256) from compact 16x8 representation.
* cipher/Makefile.am: Add gost-sb.h dependency to gost28147.lo
* cipher/gost.h: Add sbox to the GOST28147_context structure.
* cipher/gost28147.c (gost_setkey): Set default s-box to test s-box from
GOST R 34.11 (this was the only one S-box before).
* cipher/gost28147.c (gost_val): Use sbox from the context.
