syscall: fix for Plan 9 build
exec_plan9.go:
. Adjusted return argument to match other changes.
#mksyscall.pl:
. Replaced "err = e1" with "err = NewError(e1)".
* Change abandoned, Russ made a better suggestion involving
syscall_plan9.go.
syscall_plan9.go:
. Removed redundant "err = nil" lines.
. Adjusted //sys lines for mksyscall.pl.
* Replaced "err string" with "err ErrorString" in return arguments.
zsyscall_plan9_386.go:
. This module ought to be generated, but as it exists in the
repository, I rebuilt it and checked that it matched expectations.
Anybody is welcome to remove this from the repository if
they feel it should go, but remember that not all Plan 9
installations have a working Perl.

exp/ssh: alter Session to match the exec.Cmd API
This CL inverts the direction of the Stdin/out/err members of the
Session struct so they reflect the API of the exec.Cmd. In doing so
it borrows heavily from the exec package.
Additionally Shell now returns immediately, wait for completion using
Wait. Exec calls Wait internally and so blocks until the remote
command is complete.
Credit to Gustavo Niemeyer for the impetus for this CL.

html: refactor parse test infrastructure
My excuse for doing this is that test cases with newlines in them didn't

parse_test.go to use fewer channels and pipes, and just call a

unused by client code, there is no API change and no spec change yet.

misc/windows packager development intermediate check-in
The installer now: allows a user to select an alternative
install directory, it now adds a Go folder to the Programs
Menu, and it places two shortcuts on the user's desktop.
The Program Menu folder contains shortcuts to the uninstaller
and two batch files, go.bat and godoc.bat. The desktop
shortcuts also point to go.bat and godoc.bat.
go.bat sets the Go environment, including Path, and spawns a
Window's shell. godoc.bat starts the godoc server at
localhost:6060 then spawns a browser window pointing to the
document server.
Setting the environment temporarily and spawning a shell, via
go.bat, should be safer than messing with the system's environment
and it makes the user experience a bit more streamlined.
The packager does work in its current state but it still needs
some polishing. And yes, the plan is to add a dialogue to allow
the user to decline the desktop shortcuts.

allow copy of struct containing unexported fields
An experiment: allow structs to be copied even if they
contain unexported fields. This gives packages the
ability to return opaque values in their APIs, like reflect
does for reflect.Value but without the kludgy hacks reflect
resorts to.
In general, we trust programmers not to do silly things
like *x = *y on a package's struct pointers, just as we trust
programmers not to do unicode.Letter = unicode.Digit,
but packages that want a harder guarantee can introduce
an extra level of indirection, like in the changes to os.File
in this CL or by using an interface type.
All in one CL so that it can be rolled back more easily if
we decide this is a bad idea.
