Remove the private implementation of 32-bit rotation and unaligned
access with byteswapping.As a bonus, fixes sparse warnings:

This reverts commit bd699f2df6dbc2f4cba528fe598bd63a4d3702c5,
which causes camellia to fail the included self-test vectors.
It has also been confirmed that it breaks existing encrypted
disks using camellia.Signed-off-by: Herbert Xu

Analogously to camellia7 patch, move
"absorb kw2 to other subkeys" and "absorb kw4 to other subkeys"
code parts into camellia_setup_tail(). This further reduces
source and object code size at the cost of two brances
in key setup code.Signed-off-by: Denys Vlasenko

Move "key XOR is end of F-function" code part into
camellia_setup_tail(), it is sufficiently similar
between camellia_setup128 and camellia_setup256.Signed-off-by: Denys Vlasenko

unifies encrypt/decrypt routines for different key lengths.
This reduces module size by ~25%, with tiny (less than 1%)
speed impact.
Also collapses encrypt/decrypt into more readable
(visually shorter) form using macros.Signed-off-by: Denys Vlasenko

Remove unused macro params.
Use (u8)(expr) instead of (expr) & 0xff,
helps gcc to realize how to use simpler commands.
Move CAMELLIA_FLS macro closer to encrypt/decrypt routines.Signed-off-by: Denys Vlasenko

Move huge unrolled pieces of code (3 screenfuls) at the end of
128/256 key setup routines into common camellia_setup_tail(),
convert it to loop there.
Loop is still unrolled six times, so performance hit is very small,
code size win is big.Signed-off-by: Denys Vlasenko

Optimize GETU32 to use 4-byte memcpy (modern gcc will convert
such memcpy to single move instruction on i386).
Original GETU32 did four byte fetches, and shifted/XORed those.Signed-off-by: Denys Vlasenko

Rename some macros to shorter names: CAMELLIA_RR8 -> ROR8,
making it easier to understand that it is just a right rotation,
nothing camellia-specific in it.
CAMELLIA_SUBKEY_L() -> SUBKEY_L() - just shorter.Move be32 cpu conversions out of en/decrypt128/256 and into
camellia_en/decrypt - no reason to have that code duplicated twice.Signed-off-by: Denys Vlasenko

Move code blocks around so that related pieces are closer together:
e.g. CAMELLIA_ROUNDSM macro does not need to be separated
from the rest of the code by huge array of constants.Remove unused macros (COPY4WORD, SWAP4WORD, XOR4WORD[2])
Drop SUBL(), SUBR() macros which only obscure things.
Same for CAMELLIA_SP1110() macro and KEY_TABLE_TYPE typedef.Remove useless comments:
/* encryption */ -- well it's obvious enough already!
void camellia_encrypt128(...)Combine swap with copying at the beginning/end of encrypt/decrypt.
