GCM: Move gcm_table initialization to setkey
* cipher/cipher-gcm.c: Change all 'c->u_iv.iv' to
'c->u_mode.gcm.u_ghash_key.key'.
(_gcry_cipher_gcm_setkey): New.
(_gcry_cipher_gcm_initiv): Move ghash initialization to function above.
* cipher/cipher-internal.h (gcry_cipher_handle): Add
'u_mode.gcm.u_ghash_key'; Reorder 'u_mode.gcm' members for partial
clearing in gcry_cipher_reset.
(_gcry_cipher_gcm_setkey): New prototype.
* cipher/cipher.c (cipher_setkey): Add GCM setkey.
(cipher_reset): Clear 'u_mode' only partially for GCM.
--
GHASH tables can be generated at setkey time. No need to regenerate
for every new IV.
