go vet detected that the value of pkgIndexOnce
is copied through assignments in the test.
This patch fixes that by converting it to *sync.Once instead.

These changes will need to be reverted once we use
vendoring in the stdlib again, but it's trivial to
do so when the time comes.

Editor modes that invoke the goimports command on temporary copies
of actual source files will need to invoke goimports -srcdir now to say
where the real source directory is. Otherwise goimports will not consider
vendored or internal packages when looking for new imports.
In lieu of a test for cmd/goimports (because it has no tests),
a command transcript:
$ cd /tmp
$ cat x.go
package p
var _ = hpack.HuffmanDecode
$
$ GOPATH= goimports < x.go
package p
var _ = hpack.HuffmanDecode
$ GOPATH= goimports x.go
package p
var _ = hpack.HuffmanDecode
$
But with the new flag:
$ GOPATH= goimports -srcdir $GOROOT/src/math < x.go
package p
import "golang.org/x/net/http2/hpack"
var _ = hpack.HuffmanDecode
$ GOPATH= goimports -srcdir $GOROOT/src/math x.go
package p
import "golang.org/x/net/http2/hpack"
var _ = hpack.HuffmanDecode
$
The tests in this CL and the above transcript assume that
$GOROOT/src/vendor/golang.org/x/net/http2/hpack exists.
It did in 40a26c9, but it does not today.
It will again soon (once Go 1.7 opens).
For golang/go#12278 (original request).

AddImport and AddNamedImport attempt to place new
imports in roughly the correct place--and thus the
correct group--by matching prefixes. Matching prefixes
byte-by-byte led to "regexp" being grouped with "rsc.io/p".
Instead, match prefixes by segments.

Fixes 7866. Adds a test case.
When trying to add newlines before certain imports via text manipulation,
a regex is used to iterate over all imports. The regex failed to match
dot imports because \w doesn't match a literal dot. This changes the regex
to accept a dot as well.

The issue occurs only when deleting an import that has a blank line immediately preceding,
and other imports before that.
Currently, DeleteImport assumes there's a blank line-sized hole left behind
where the import was, and always deletes it. That blank line-sized hole is there in all cases
except the above edge case.
This fix checks for that edge case, and does not remove the blank line-sized hole.
The CL also adds a previously failing test case that catches this scenario. After the change to
DeleteImport, the new test passes (along with all other tests).
Fixesgolang/go#7679.
Note that there is no attempt to ensure the result *ast.File and *token.FileSet are perfectly
matching to what you would get if you printed the AST and parsed it back. This is how the
rest of the package and the current tests work (i.e., they only check that printing the AST gives
the correct output).
Changing that is very hard, if not impossible, at least not
without resorting to manipulating AST via printing, text manipulation and parsing.
This is okay for most usages, but it does create potential problems. For example,
astutil.Imports() currently only works correctly on freshly parsed AST. If that AST
is manipulated via astutil funcs, then Imports() may not always generate correct
output. However, thas is a separate issue and should be treated as such.

Assuming:
1) package declaration does not exist
2) the Fragment option is set
3) a main function exists
We will assume it is a main package and add the declaration.
This change also sets the Fragment option in goimports.

If $GOPATH was large, or $GOPATH was $HOME and $HOME/src had
many files, the unbounded concurrency in loadPkgIndex/loadPkg
could make the operating system unhappy with so many
threads. (sigh once again for no async file IO and needing
threads for file operations)
In addition, don't call go/build.Context.Import on directories
that we've already determined to have no go files in them.
It's just a waste of time. Makes it about 3x faster on my
machine with hot caches and a big $HOME/src.

goimports to use the package name as a local qualifier in an import.
For example, if findImports("pkg", "X") returns ("foo/bar",
rename=true), then goimports adds the import line:
import pkg "foo/bar"
to satisfy uses of pkg.X in the file.
This change doesn't add any implementations of rename=true, though one
is sketched in a TODO.

Because goimports also sorts stdlib-vs-external differently
(whereas gofmt just sorts string-wise), we need to put a blank
