Previously Request and Response had redundant fields for
Referer, UserAgent, and cookies which caused confusion and
bugs.  It also didn't allow us to expand the package over
time, since the way to access fields would be in the Headers
one day and promoted to a field the next day.  That would be
hard to gofix, especially with code ranging over Headers.

After a discussion on the mail package's design with a similar
problem, we've designed to make the Headers be the source of
truth and add accessors instead.

Request:
change: Referer -> Referer()
change: UserAgent -> UserAgent()
change: Cookie -> Cookies()
new: Cookie(name) *Cookie
new: AddCookie(*Cookie)

Response:
change: Cookie -> Cookies()

Cookie:
new: String() string

Attributes without value are commen in html and the xml
parser will accept them in non-strict mode and use the
attribute name as value. Thus parsing <p nowrap> as
<p norwar="nowrap">.

It was always a weird interface but I didn't know what I
was doing at the time.  rsc questioned me about it then
but didn't press on it during review.  Then adg bugged me
about it too recently.

So clean it up. It parallels the Writer struct too.

I don't think we've discussed this API enough.

It comes up often enough that it's time to provide

Still TODO: parsing optimizations

make_perl_groups.pl is copied with minimal modifications
(just to generate Go syntax instead of C++) from RE2.
Google Inc is "The RE2 Author" of that file and is one of
the Go Authors, so copyright changed to the Go Authors instead.

The "elf.h" header changes involve only comments, the released
Plan 9 C preprocessing function does not cope with multiline
comments following the #define keyword.  All multiline comments
have been moved to the line above the associated definition.
Sigh!  Fixing the Plan 9 compiler is not an option.

<time.h> does not exist in the Plan 9 Native library.  I have
moved it from src/cmd/ld/pe.h to include/u.h. RSC correctly points
out that this copy of <u.h> is not the one used to compile the
Go release on Plan 9 platforms.
