encoding/asn1: fix test on OpenBSD
time.Parse uses time.Local if it has the right zone offset,
otherwise it calls time.FixedZone. The test's use of reflect.DeepEqual
meant that the test expected time.FixedZone always, failing
when the local time zone really would have used -0700 for
that time. The fix is to format the time to display only the
pieces we intend to test.

exp/ssh: Add Start(cmd string) and Signal(sig string) to Session. Rename Exec to Run.
Exec() has been renamed to Run() in keeping with the os/exec API.
Added func (*Session) Start(cmd string) which starts a remote process but unlike Run() doesn't wait for it to finish before returning.
Run() has been refactored to use Start internally. Its really just a refactoring, no new code but some extra functionality was won.
Also added func (*Session) Signal(sig signal) which sends a UNIX signal to a remote process. This is espcially useful in conjunction with Start() as the two allow you to start a remote process, monitor its stdout/stderr, and send it a TERM/HUP/etc signal when you want it to close.

math/big: use recursive subdivision for significant speedup
This change adds the second aspect to the conversion code, the

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.

This CL inverts the direction of the Stdin/out/err members of the

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.
