The comment of Process() implies src can be nil, but it didn't handle
nil src correctly before because parse() doesn't expect nil src.
Passing []byte(nil) to parser.ParseFile() results in error and parse()
tries to parse again by modifying src if src is statement list.
This problem isn't related with cmd/goimports because goimports doesn't
pass []byte(nil) to Process() as src.

Previous work to resolvegolang/go#18201 increased the maximum line
length that goimports could handle to 1MiB (CL83800), but generated code
can result in Go files with longer lines. Use a bufio.Reader instead of
a bufio.Scanner to support arbitrarily long lines, as permitted by the
Go spec.

This change set fixes the issue by specifying a max buffer size of ~1 megabyte for Scanner.
Previously the max was not set resulting in the default max which is ~64k. This increased max should not increase
memory use for smaller, normal files because it is a max and the code expands the buffer as needed for large tokens.
The change set includes an additional change to return an error from the Scanner which was ignored previously.

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).

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.

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.

Because goimports also sorts stdlib-vs-external differently
(whereas gofmt just sorts string-wise), we need to put a blank
line between imports of different classes. This happened in
some cases, but not all.
