This doesn't change the existing restriction with disallows
spaces in import paths (as found in an import declaration).
It simply permits packages to be under a directory name that
may contain spaces.

Verified manually that it works. This could use a test, but the
change is trivial. We also can't use the existing test framework
(under test/) because the way those tests are run with test/run.go,
the mechanims for compiling a directory, even if it contains blanks
it its name, does't produce compiler paths with blanks
(the compilation is local).

Fixes #20306.

The ascii85, base32 and base64 packages all contain a test called
TestDecoderBuffering.  Each of these tests contain a loop that ignores
the error returned from the Read method of their decoders.  The result
being that the tests loop for ever if the decoders actually return an
error.  This commit fixes the issue by terminating the loops if an error
occurs and failing the tests with a suitable error message.

If an image has been cropped horizontally, writeImageBlock detects that
its width and Stride differ and acts accordingly.

However, if an image has been cropped vertically, trimming from the
bottom, the whole original image will be written in place.  This results
in more data in the LZW stream than necessary, and many decoders
including image/gif's itself will fail to load.

In some cases the netpoll code can cause a spurious wakeup. This is
normally harmless, as the woken up code simply retries the operation.
However, for connect, the test we were using to see whether the
connect had succeeded (setsockopt(SO_ERROR)) was not reliable in the
case of a spurious wakeup.  Change to using a reliable test (getpeername).
On Darwin we used a different technique: a second call to connect;
change Darwin to use getpeername as well.

Return the result of getpeername to avoid having to call it twice.

The existing docs states that, get looks for a branch or tag
that matches the locally installed version of Go.
First, this is only working for "go1", so it could be confusing.
Second, "If no such version exists it retrieves the most recent
version of the package". It's more the default branch, by git defaults,
rather than most recent version.

This should address the potential unclear parts.

Errorf identify the failure as being in testEqual itself which is not
very useful.  This commit fixes the problem by adding a call to the
new t.Helper method in each of the testEqual functions.  The line
numbers output when errors do occur now identify the real source of
the error.

The existing code used Type.String() to obtain the name of a type;
specifically type reflect.Method in this case. However, Type.String()
formatting is intended for error messages and uses the format
pkgpath.name instead of pkgname.name if a package (in this case
package reflect) is imported multiple times. As a result, the
reflect.Method type detection failed under peculiar circumstances
(see the included test case).
