Russ Cox e1ee3b5db6 reflect: add Type.Implements, Type.AssignableTo, Value.CallSlice; make Set match Go
This CL makes reflect require that values be assignable to the target type
in exactly the same places where that is the rule in Go.  It also adds
the Implements and AssignableTo methods so that callers can check
the types themselves so as to avoid a panic.

Before this CL, reflect required strict type identity.

This CL expands Call to accept and correctly marshal arbitrary
argument lists for variadic functions; it introduces CallSlice for use
in the case where the slice for the variadic argument is already known.

Fixes #327.
Fixes #1212.

After installing Go, you can view a nicely formatted
doc/install.html by running godoc --http=:6060
and then visiting http://localhost:6060/doc/install.html.

Binary Distribution Notes

If you have just untarred a binary Go distribution, you need to set
the environment variable $GOROOT to the full path of the go
directory (the one containing this README).  You can omit the
variable if you unpack it into /usr/local/go, or if you rebuild
from sources by running all.bash (see doc/install.html).
You should also add the Go binary directory $GOROOT/bin
to your shell's path.

For example, if you extracted the tar file into $HOME/go, you might
put the following in your .profile:

    export GOROOT=$HOME/go
    export PATH=$PATH:$GOROOT/bin

See doc/install.html for more details.
