The special case in the spec is that you can take the
address of a composite literal using the & operator.
A composite literal is not, however, generally addressable,
and the slice operator requires an addressable argument,
so [3]int{1,2,3}[:] is invalid. This tutorial code and one bug
report are the only places in the tree where it appears.

- syscall (not os) now defines the Errno type.
- the low-level assembly functions Syscall, Syscall6, and so on
return Errno, not uintptr
- syscall wrappers all return error, not uintptr.

Also update the big example to the new template system.
There are a number of other examples that should be
extracted; this CL serves as an introduction to the
approach.

Fixes#1742.
I hope.
Also this picks up an update to go_tutorial.html that should already have happened.

Besides being more correct, it protects against people accidentally
exchanging the permission and open mode arguments to Open.

note that sortmain.go has been run through hg gofmt;
only the formatting of the day initializers changed.
i'm happy to revert that formatting if you'd prefer.

This change removes the necessity to have GOBIN in $PATH,
and also doesn't assume that the build is being run from
$GOROOT/src. This is a minimal set of necessary changes
to get Go to build happily from the FreeBSD ports
collection.

the bash scripts and makefiles for building go didn't take into account
the fact $GOROOT / $GOBIN could both be directories containing whitespaces,
and was not possible to build it in such a situation.
this commit adjusts the various makefiles/scripts to make it aware of that
possibility, and now it builds successfully when using a path with whitespaces
as well.
Fixes#115.

*** Reason for rollback ***
roll back the changes to the tutorial programs (only) since they
break the automated processing used to create the tutorial.
*** Original change description ***
apply gofmt to the LGTM-marked files from 34501
that have not changed since I applied gofmt.

echo back context of call in error if likely to be useful.
For example, if os.Open("/etc/passwd", os.O_RDONLY)
fails with syscall.EPERM, it returns as the os.Error
&PathError{
Op: "open",
Path: "/etc/passwd"
Error: os.EPERM
}
which formats as
open /etc/passwd: permission denied

as a reminder, the old conversion
was that you could write
var arr [10]byte;
var slice []byte;
slice = arr;
but now you have to write
slice = &arr;
the change eliminates an implicit &, so that
the only implicit &s left are in the . operator
and in string(arr).
also, removed utf8.EncodeRuneToString
in favor of string(rune).
