The set of errors forwarded by the os package varied with system and
was therefore non-portable.
Three helpers added for portable error checking: IsExist, IsNotExist, and IsPermission.
One or two more may need to come, but let's keep the set very small to discourage
thinking about errors that way.

This CL is in part a proposal for how to write these sections:
- Brief discussion of change
- No attempt to analyze the thinking about it
- Old code
- New code, runnable if possible
- How to update old programs

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.
