image/draw benchmarks show <1% change for the fast paths.
The slow paths got worse by 1-4%, but they're the slow paths.
I don't care so much about them, and presumably compiler improvements
could claw it back.

IIUC 6g's inlining is enabled by default now.

It works with NewTicker too, but is potentially a bit less efficient,
and reads wrong.

This is what happens when you TBR Windows changes, I guess.

This allows HTML pages to specify arbitrary data in a header:

<!--{
        "Title": "The page title",
        ...
}-->

replacing the old style comments:

<!-- title The page title -->

Previously, a timeout (in int64 nanoseconds) applied to a granularity
even smaller than one operation:  a 100 byte read with a 1 second timeout
could take 100 seconds, if the bytes all arrived on the network 1 second
apart.  This was confusing.

Rather than making the timeout granularity be per-Read/Write,
this CL makes callers set an absolute deadline (in time.Time)
after which operations will fail.  This makes it possible to
set deadlines at higher levels, without knowing exactly how
many read/write operations will happen in e.g. reading an HTTP
request.

First was, apart from adding tests, a single line of code (to add the
constructor function). Adding SHA512-based hashing to crypto/hmac
required minor rework of the package because of a previously hardcoded
block-size in it's implementation. Instead of using a hash.Hash
generator function the constructor function now uses a crypto.Hash
type, which was extended to expose information about block size.

The only standard library package impacted by the change is
crypto/tls, for which the fix is included in this patch. It might be
useful to extend gofix to include this API change too.
