This AEAD algorithm provides a way to make nonce-reuse a not critical
issue. That is particular useful to stateless servers that cannot
ensure that the nonce will not repeat. This cipher is used by
draft-ietf-ntp-using-nts-for-ntp-17.

Move and rename block_mulx --> _cmac128_block_mulx.

* xts.c (xts_shift): Arrange with a single write to u64[1].
* cmac.c (block_mulx): Rewrite to work in the same way as
xts_shift, with 64-bit operations. XTS and CMAC use opposite
endianness, but otherwise, these two functions are identical.

(cherry picked from commit 73d3c6d5)

Intended to silence warning from the clang static analyzer.

* rsa-sign-tr.c (sec_equal): Fix accidental use of C99 for loop.
Reported by Andreas Gustafsson.
* testsuite/rsa-sec-decrypt-test.c (test_main): Likewise.

* testsuite/rsa-encrypt-test.c (test_main): Fix allocation of
decrypted storage. Update test of rsa_decrypt, to allow clobbering
of all of the passed in message area.

Patch from Simo Sorce.

Use new local helper functions, with their own itch functions.
