Andreas Auernhammer c2843e01d9 poly1305: implement a subset of the hash.Hash interface 
This CL adds the poly1305.MAC type which implements a
subset of the hash.Hash interface. With MAC it is possible
to compute an authentication tag of data without copying
it into a single byte slice.

This commit modifies the reference/generic and the
AMD64 assembler but not the ARM/s390x implementation
to support an io.Writer interface.

Updates golang/go#25219

Adam Langley 3ded668c53 poly1305: enable assembly for ARM in Go 1.6. 
5f31782cfb added build constraints to
disable assembly for Go 1.6 but didn't add the needed tags to the ARM
files. Also, it's not clear that was needed as the error given in
golang/go#17424 only complains about the chacha20poly1305 package.

This change reenables the assembly for Go 1.6 in the poly1305 package.
Tested with 1.6.3 and 1.5.4.

Fixes golang/go#17512.

Adam Langley a81735b1ea poly1305: rename files to sum_𝑥.s 
Since the wrapper files are called sum_𝑥.go, it makes sense that the
assembly files would be named similarly.
