Missed a case for variadic functions with too few arguments.
The code passes, and with the right error, but might as well record the test case.

The recent addition of automatic function invocation generated
some troublesome ambiguities. Restore the previous behavior
and compensate by providing a "call" builtin to make it easy to
do what the automatic invocation did, but in a clear and explicit
manner.
Fixes#3140.
At least for now.

I tried before to make relative imports work by simply
invoking the compiler in the right directory, so that
an import of ./foo could be resolved by ./foo.a.
This required creating a separate tree of package binaries
that included the full path to the source directory, so that
/home/gopher/bar.go would be compiled in
tmpdir/work/local/home/gopher and perhaps find
a ./foo.a in that directory.
This model breaks on Windows because : appears in path
names but cannot be used in subdirectory names, and I
missed one or two places where it needed to be removed.
The model breaks more fundamentally when compiling
a test of a package that lives outside the Go path, because
we effectively use a ./ import in the generated testmain,
but there we want to be able to resolve the ./ import
of the test package to one directory and all the other ./
imports to a different directory. Piggybacking on the compiler's
current working directory is then no longer possible.
Instead, introduce a new compiler option -D prefix that
makes the compiler turn a ./ import into prefix+that,
so that import "./foo" with -D a/b/c turns into import
"a/b/c/foo". Then we can invent a package hierarchy
"_/" with subdirectories named for file system paths:
import "./foo" in the directory /home/gopher becomes
import "_/home/gopher/foo", and since that final path
is just an ordinary import now, all the ordinary processing
works, without special cases.
We will have to change the name of the hierarchy if we
ever decide to introduce a standard package with import
path "_", but that seems unlikely, and the detail is known
only in temporary packages that get thrown away at the
end of a build.
Fixes#3169.

Except for the tests, this is mostly deleting code:
- removed several exprListModes:
blankStart: easily done explicitly, and trailing blanks
are cleaned up by the trimmer post-pass
blankEnd: never used
commaSep: all exprLists calls had this set
- added test cases for multi-line returns
(for a later fix of issue 1207)
- no formatting changes

Fixes a problem Rob is having with goprotobuf.
Cannot add a test because the same case is more broken
when using ./ imports. That still needs to be fixed,
and is one aspect of issue 3169.

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.

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.
