math/big: use recursive subdivision for significant speedup
This change adds the second aspect to the conversion code, the
use of large divisiors (powers of big base) to greatly speed up
the divsion of large numbers. Speedups of 30x are common in the
large cases. Also includes new tests and tuning code for the
key internal parameters.

exp/ssh: messages now contain remote channel's id instead of local id
According to http://www.ietf.org/rfc/rfc4254.txt most channel messages contain the channel id of the recipient channel, not the sender id. This allows the recipient connection multiplexer to route the message to the correct channel.
This changeset fixes several messages that incorrectly send the local channel id instead of the remote channel's id.
While sessions were being created and closed in sequence channels in the channel pool were freed and reused on the server side of the connection at the same rate as was done on the client, so the channel local and remote channel ids always corresponded. As soon as I had concurrent sessions on the same clientConn the server started to complain of 'uknown channel id N' where N is the local channel id, which is actually paired with server channel id K.

text/template: new, simpler API
The Set type is gone. Instead, templates are automatically associated by
being parsed together; nested definitions implicitly create associations.
Only associated templates can invoke one another.
This approach dramatically reduces the breadth of the construction API.
For now, html/template is deleted from src/pkg/Makefile, so this can
be checked in. Nothing in the tree depends on it. It will be updated next.

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.

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.
