Vladislav Bolkhovitin 59019ae405 Use get/put_unaligned() instead of open coding these such that the ...

compiler can generate better code.

As an example, the get_unaligned_be24() function used in the
implementation of READ_6, WRITE_6 and VERIFY_6 together with
"& 0x1f0000" is inlined by the compiler and is translated as
follows on an x86_64 system (2031616 equals 0x1f0000):

        movl    0(%r13), %r11d
        bswapl  %r11d
        andl    $2031616, %r11d

Also eliminate a conditional branch instruction from get_trans_len_1_256().
