Using the previous commit's inredirection mechanism for SHA1, support a chunked implementation of SHA1_Update() that limits the amount of data in the chunk passed to SHA1_Update(). This is enabled by using the Makefile variable SHA1_MAX_BLOCK_SIZE to specify chunk size. When using Apple's CommonCrypto library this is set to 1GiB (the implementation cannot handle more 4GiB).
