The 512 MB array causes load delays on some systems.
Now that we have recover, we can do all the tests in
one binary, so that the delay is incurred just once.

This makes sure that all JS newlines are encoded in JSON.
It also moots a TODO about possibly escaping supplemental codepoints.
I served:
Content-Type: text/javascript;charset=UTF-8
var s = "%s";
document.write("<p>", s, "</p><ol>");
for (var i = 0; i < s.length; i++) {
document.write("<li>", s.charCodeAt(i).toString(16), "</li>");
}
document.write("</l>");
where %s was replaced with bytes "\xf0\x9d\x84\x9e" to test
straight UTF-8 instead of encoding surrogates separately.
Recent Firefox, Chrome, and Safari all decoded it properly.
I have yet to try it on IE or older versions.

The template
"<a="
caused an infinite loop in escape text.
The change to tTag fixes that and the change to escape.go causes
escapeText to panic on any infinite loop that does not involve
a state cycle.

The Dwarf info has the full typenames, the go *struct runtime.commonType

One benefit of websocket is that it is full-duplex so that it could
send and receive at the same time.
This CL makes websocket goroutine safe, so user could use websocket
both on goroutine for read and on goroutine for write.

When templates are stored in external files, developers often embed
comments to explain&|disable code.
<!-- Oblique reference to project code name here -->
{{if .C}}...{{else}}<!-- commented out default -->{{end}}
This unnecessarily increases the size of shipped HTML and can leak
information.
This change elides all comments of the following types:
1. <!-- ... --> comments found in source.
2. /*...*/ and // comments found in <script> elements.
3. /*...*/ and // comments found in <style> elements.
It does not elide /*...*/ or // comments found in HTML attributes:
4. <button onclick="/*...*/">
5. <div style="/*...*/">
I can find no examples of comments in attributes in Closure Templates
code and doing so would require keeping track of character positions
post decode in
<button onclick="/*...*/">
To prevent token joining, /*comments*/ are JS and CSS comments are
replaced with a whitespace char.
HTML comments are not, but to prevent token joining we could try to
detect cases like
<<!---->b>
</<!---->b>
which has a well defined meaning in HTML but will cause a validator
to barf. This is difficult, and this is a very minor case.
I have punted for now, but if we need to address this case, the best
way would be to normalize '<' in stateText to '<' consistently.
The whitespace to replace a JS /*comment*/ with depends on whether
there is an embedded line terminator since
break/*
*/foo
...
is equivalent to
break;
foo
...
while
break/**/foo
...
is equivalent to
break foo;
...
Comment eliding can interfere with IE conditional comments.

<!--[if IE 6]>
<p>You are using Internet Explorer 6.</p>
<![endif]-->
/*@cc_on
document.write("You are using IE4 or higher");
@*/
I have not encountered these in production template code, and
the typed content change in CL 4962067 provides an escape-hatch
if conditional comments are needed.

This simplifies transition functions to make it easier to reliably
elide comments in a later CL.
Before:
- transition functions are responsible for detecting special end tags.
After:
- the code to detect special end tags is done in one place.
We were relying on end tags being skipped which meant we were
not noticing comments inside script/style elements that contain no
substitutions.
This change means we will notice all such comments where necessary,
but stripTags will notice none since it does not need to. This speeds
up stripTags.

The documentation for bytes.Replace says it copies
the slice but it won't necessarily copy them. Since
the data is mutable, breaking the contract is an issue.
We either have to fix this by making the copy at all
times, as suggested in this CL, or we should change the
documentation and perhaps make better use of the fact
it's fine to mutate the slice in place otherwise.

Use gobs to serialize indexes instead of encoding/binary.
Even with gobs, serialize data in slices instead of
applying gob to the entire data structure at once,
to reduce the amount of extra buffer memory needed
inside gob.
7x faster Write/Read for new BenchmarkSaveRestore
compared to old code; possibly because encoding/binary
is more expensive for int32 slice elements (interface
call to get little/big endian encoding), while gob's
encoding is fixed (unconfirmed).
new (using gobs):
suffixarray.BenchmarkSaveRestore 1 2153604000 ns/op
old (using encoding/binary):
suffixarray.BenchmarkSaveRestore 1 15118322000 ns/op
The actual serialized data is slightly larger then using
the old code for very large indices because full 32bit indices
require 5bytes using gobs instead of 4bytes (encoding/binary)
in serialized form.

Instead of erroring on actions inside comments, use existing escaping
pipeline to quash the output of actions inside comments.
If a template maintainer uses a comment to disable template code:
{{if .}}Hello, {{.}}!{{end}}
->
<!--{{if true}}Hello, {{.}}!{{end}}-->
will result in
<!--Hello, !-->
regardless of the value of {{.}}.
In a later CL, comment elision will result in the entire commented-out
section being dropped from the template output.
Any side-effects in pipelines, such as panics, will still be realized.
