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.

This feature should make it easier to look at very large
directory trees.
- a new mode (URL: /pkg/?m=flat) shows directory listings w/o
indentation and entries with full path (html and text mode)
- in text mode, hierarchical (non-flat) directory listings are
now presented with indentation (/pkg/?m=text)
- in html mode, hierarchical (non-flat) directory listings are
presented with slightly less indentation
- there is an internal hook for programmatic control of the
display mode (for specialized versions of godoc).

Work around a bug that was fixed after OpenBSD 5.0 - a request for
kern.hostname or kern.domainname with a nil value for oldp will result
in a length of zero being returned. If we hit this case use a length
of MAXHOSTNAMELEN (256).

Move the existing darwin/freebsd specific nametomib implementation
into the respective operating system dependent files.
Provide a nametomib implementation for openbsd, which operates on a
sysctl MIB that has been pre-generated from the various system headers
by mksysctl_openbsd.pl.

Making Value opaque means we can drop the interface kludges
in favor of a significantly simpler and faster representation.
v.Kind() will be a prime candidate for inlining too.

I cannot explain why BenchmarkSkipValue gets faster.
Maybe it is one of those code alignment things.

Fixes use of c after Dial failure (causes crash).
May fix Dial failure by listening to 127.0.0.1:0
instead of 0.0.0.0:0 (tests should only listen on
localhost).

The wrong length was being sent, and two parameters
were also transposed. Made the record type be a type
and made the constants typed, to prevent that sort
of bug in the future.

text/template does this (in an entirely different way), so
make html/template do the same. Before this fix, the template
{{.}} given a pointer to a string prints its address instead of its
value.

Ensure that empty NameLists always return
a zero length []string, not nil.
In practice NameLists are only used in a few
message types and always consumed by a for
range function so the difference between nil
and []string{} is not significant.
Also, add exp/ssh to pkg/Makefile as suggested
by rsc.

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.
