Victor Hsieh f77c5729a6 authfs: create a chunked reader with fs-verity verification 
The new chunked reader uses a Merkle tree to verify each chunk read of
the corresponding backing file. The reader also accepts an
autheneticator for signature verification, though it is currently a fake
implementation due to the lack of PKCS#7 signature support in BoringSSL
(b/170494765).

Test: atest authfs_host_test_src_lib
Bug: 171310075

fs-verity signing

With a key pair, fs-verity signature can be generated by simply running fsverity command line tool from fsverity-util.

fsverity sign test.data test.data.fsv_sig --key=key.pem --cert=cert.pem
