Fix SipHash-2-4 performance for non multiple of 8 buffers.
...
Code cribbed from Andrew Moon's Public Domain SipHash-2-4
implementation (which IMO is also cleaner).
Fixes bug 17544.

Fix unaligned access in SipHash-2-4.
...
The compiler is allowed to assume that a "uint64_t *" is aligned
correctly, and will inline a version of memcpy that acts as such.
Use "uint8_t *", so the compiler does the right thing.

Add another year to our copyright dates.
...
Because in 95 years, we or our successors will surely care about
enforcing the BSD license terms on this code. Right?

csiphash: don't attempt unaligned access
...
In digestmap_set/get benchmarks, doing unaligned access on x86
doesn't save more than a percent or so in the fast case. In the
slow case (where we cross a cache line), it could be pretty
expensive. It also makes ubsan unhappy.

Appropriately condition the _le64toh macro definition for OpenBSD.

Raw import of Marek Majkowski's cisphash.c
...
siphash is a hash function designed for producing hard-to-predict
64-bit outputs from short inputs and a 128-bit key. It's chosen for
security and speed.
See https://131002.net/siphash/ for more information on siphash.
