Presumably something about the very large go/build
doc comment breaks the build constraint parser in
cmd/dist. I don't feel like debugging C code right now,
so move it into its own file. If cmd/dist decides doc.go
is not part of the package, it will still build correctly.

- Define what it means for two identifiers to be unique.
- The current spec is incorrect about exported
identifiers: for instance, it excluded fields
of non-exported types of exported variables
from being exported. It is easier to leave
the detailed specification away and let the
rest of the spec govern access of exported
identifiers.
- The current spec is incorrect about qualified
identifiers: It simply required that an identifier
be exported to be valid in a qualified identifier.
However, qualified identifiers can only access
exported identifiers declared in the package
block of the imported package.
Fixes#1551.

In addition to these fixes, all commands now take a list of
go files as a way to specify a single package, just as go build and
go run always have. This means you can:
go list -json x.go
go fix x.go
go vet x.go
go test x_test.go
Preliminary tests in test.bash.
Mainly testing things that the ordinary build does not.
I don't mind if the script doesn't run on Windows.
I expect that gccgo support is now broken, and I hope that
people will feel free to file issues and/or send CLs to fix it. :-)

This is an API change, but one I have been promising would
happen when it was clear what the go command needed.
This is basically a complete replacement of what used to be here.
build.Tree is gone.
build.DirInfo is expanded and now called build.Package.
build.FindTree is now build.Import(package, srcDir, build.FindOnly).
The returned *Package contains information that FindTree returned,
but applicable only to a single package.
build.ScanDir is now build.ImportDir.
build.FindTree+build.ScanDir is now build.Import.
The new Import API allows specifying the source directory,
in order to resolve local imports (import "./foo") and also allows
scanning of packages outside of $GOPATH. They will come back
with less information in the Package, but they will still work.
The old go/build API exposed both too much and too little.
This API is much closer to what the go command needs,
and it works well enough in the other places where it is
used. Path is gone, so it can no longer be misused. (Fixes issue 2749.)
This CL updates clients of go/build other than the go command.
The go command changes are in a separate CL, to be submitted
at the same time.

The strikes against it are:
1. It does not take path boundaries into account.
2. It assumes that Windows==case-insensitive file system
and non-Windows==case-sensitive file system, neither of
which is always true.
3. Comparing ToLower against ToLower is not a correct
implementation of a case-insensitive string comparison.
4. If it returns true on Windows you still don't know how long
the matching prefix is in bytes, so you can't compute what
the suffix is.

In -test.short mode, skip measuring the upper bound of time
sleeps. The API only guarantees minimum bounds on sleeps,
anyway, so this isn't a bug we're ignoring as much as it is
simply observing bad builder virtualization and/or loaded
machines.
We keep the test in full mode where developers will
presumably be running on a lightly-loaded, native, fast
machine.

When we first wrote the method set definition, we had long
discussions about whether method sets applied to all types
or just named types, and we (or at least I) concluded that it
didn't matter: the two were equivalent points of view, because
the only way to introduce a new method was to write a method
function, which requires a named receiver type.
However, the addition of embedded types changed this.
Embedding can introduce a method without writing an explicit
method function, as in:
var x struct {
sync.Mutex
}
var px *struct {
sync.Mutex
}
var _, _ sync.Locker = &x, px
The edits in this CL make clear that both &x and px satisfy
sync.Locker. Today, gccgo already works this way; 6g does not.

They are broken and hard to make work.
They have never worked: if you import "/tmp/x"
from "/home/rsc/p.c" then the compiler rewrites
this into import "/home/rsc/tmp/x", which is
clearly wrong.
Also we just disallowed the : character in import
paths, so import "c:/foo" is already not allowed.
Finally, in order to support absolute paths well in
a build tool we'd have to provide a mechanism to
instruct the compiler to resolve absolute imports
by looking in some other tree (where the binaries live)
and provide a mapping from absolute path to location
in that tree. This CL avoids adding that complexity.
This is not part of the language spec (and should not be),
so no spec change is needed.
If we need to make them work later, we can.

Fixes#2919 I believe. (gets as far as sending a CONNECT
request to my little dummy logging proxy that doesn't actually
support CONNECT now.) Untested with a real CONNECT-supporting
proxy, though.
