/*
* SHA256FinalBits
*
* Description:
* This function will add in any final bits of the message.
*
* Parameters:
* context: [in/out]
* The SHA context to update.
* message_bits: [in]
* The final bits of the message, in the upper portion of the
* byte. (Use 0b###00000 instead of 0b00000### to input the
* three bits ###.)
* length: [in]
* The number of bits in message_bits, between 1 and 7.
*
* Returns:
* sha Error Code.
