Buffer intermediate output via a bytes.Buffer and thus avoid
calling through the entire Writer stack for every item printed.
There is more opportunity for improvements along the same lines.

The allowed conversions before and after are:
type Tstring string
type Tbyte []byte
type Trune []rune
string <-> string // ok
string <-> []byte // ok
string <-> []rune // ok
string <-> Tstring // ok
string <-> Tbyte // was illegal, now ok
string <-> Trune // was illegal, now ok
Tstring <-> string // ok
Tstring <-> []byte // ok
Tstring <-> []rune // ok
Tstring <-> Tstring // ok
Tstring <-> Tbyte // was illegal, now ok
Tstring <-> Trune // was illegal, now ok
Update spec, compiler, tests. Use in a few packages.
We agreed on this a few months ago but never implemented it.
Fixes#1707.

Pass tests2.dat, test 47:
" \n "
(That is, two spaces separated by a newline)

| <body>
Also pass tests through test 49:

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.

Also introduce a new insertion heuristic:
insert new import next to existing import
with the longest matching prefix.

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.

My excuse for doing this is that test cases with newlines in them didn't
work. But instead of just fixing that, I rearranged everything in
parse_test.go to use fewer channels and pipes, and just call a
straightforward function to read test cases from a file.

Slight slow-down for printer benchmark (-0.7%) before
applying CL 5416049 (which will wash it out). Code is
cleaner and simpler.

Preamble to the simplification of the template API.
Although the signature of Parse (nee Set) changes,
it's really an internal function, used only by
text/template.

Parse {{define}} blocks during template parsing rather than separately as a set-specific thing.
This cleans up set parse significantly, and enables the next step, if we want, to unify the
API for templates and sets.
Other than an argument change to parse.Parse, which is in effect an internal function and
unused by client code, there is no API change and no spec change yet.

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.
