        This CL generalises the pair of halfConnection members that the
        serverConn holds into a single transport struct that is shared by
        both Server and Client, see also CL 5037047.

        This CL is a replacement for 5040046 which I closed by accident.

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.

        under clang-3.0. The line was added in a46819aa9150

        leftover debugging.

This addresses several use cases:

(1) <h{{.HeaderLevel}}> used to build hierarchical documents.
(2) <input on{{.EventType}}=...> used in widgets.
(3) <div {{" dir=ltr"}}> used to embed bidi-hints.

It also makes sure that we treat the two templates below the same:

<img src={{if .Avatar}}"{{.Avatar}}"{{else}}"anonymous.png"{{end}}>
<img src="{{if .Avatar}}{{.Avatar}}{{else}}anonymous.png{{end}}">

This splits up tTag into a number of sub-states and adds testcases.

The template

  <{{.}}

would violate the structure preservation property if allowed and not
normalized, because when {{.}} emitted "", the "<" would be part of
a text node, but if {{.}} emitted "a", the "<" would not be part of
a text node.

This change rewrites '<' in text nodes and RCDATA text nodes to
'&lt;' allowing template authors to write the common, and arguably more
readable:

    Your price: {{.P1}} < list price {{.P2}}

while preserving the structure preservation property.

It also lays the groundwork for comment elision, rewriting

    Foo <!-- comment with secret project details --> Bar

to

    Foo  Bar

The typical UNIX method for controlling long running process is to
send the process signals. Since this doesn't get you very far, various
ad-hoc, remote-control protocols have been used over time by programs
like Apache and BIND.

Implementing an SSH server means that Go code will have a standard,
secure way to do this in the future.

clean up duplicate environment for CGI.
overriding former by latter.
On windows, When there are duplicated environments like following,

SCRIPT_FILENAME=c:/progra~1/php/php-cgi.exe
SCRIPT_FILENAME=/foo.php

CreateProcess use first entry.

If make cgi.Handle like following,

        cgih = cgi.Handler{
                Path: "c:/strawberry/perl/bin/perl.exe",
                Dir:  "c:/path/to/webroot",
                Root: "c:/path/to/webroot",
                Args: []string{"foo.php"},
                Env:  []string{"SCRIPT_FILENAME=foo.php"},
        }

http/cgi should behave "SCRIPT_FILENAME is foo.php".
But currently, http/cgi is set duplicate environment entries.
So, browser show binary dump of "php-cgi.exe" that is specified indented
SCRIPT_FILENAME in first entry.
This change clean up duplicates, and use latters.
