We used to use build.Import to get the dependencies, but that meant
we had to repeat the check for every possible GOOS/GOARCH/cgo
combination, which took too long. So we made the test in short mode
only check the current GOOS/GOARCH/cgo combination.
But some combinations can't run the test at all. For example darwin/arm64
does not run tests with a full source file systems, so it cannot test itself,
so nothing was testing darwin/arm64. This led to bugs like #10455
not being caught.
Rewrite the test to read the imports out of the source files ourselves,
so that we can look at all source files in a directory in one pass,
regardless of which GOOS/GOARCH/cgo/etc they require.
This one complete pass runs in the same amount of time as the
old single combination check ran, so we can now test all systems,
even in short mode.

A while back we discovered that the dependencies test allowed
arbitrary dependencies for packages we forgot to list.
To stop the damage we added a grandfathered list and fixed
the code to expect unlisted packages to have no dependencies.
This CL replaces the grandfathered list with some more
careful placement of dependency rules.
Thankfully, there were no terrible inversions.

There is clearly work to do here with respect to xml name spaces,
but I don't believe the changes in this cycle are clearly correct.
The changes in this cycle have visible impact on the generated xml,
possibly breaking existing programs, and yet it's not clear that they
are the end of the story: there is still significant confusion about how
name spaces work or should work (see #9519, #9775, #8167, #7113).
I would like to wait to make breaking changes until we completely
understand what the behavior should be and can evaluate the benefit
of those breaking changes. My main concern here is that we will break
programs in Go 1.5 for the sake of name space adjustments and then
while trying to fix those other bugs we'll break programs in Go 1.6 too.
Let's wait until we know all the changes we want to make before we
decide whether or how to break existing programs.
This CL reverts:
5ae822b encoding/xml: minor changes
bb7e665 encoding/xml: fix xmlns= behavior
9f9d66d encoding/xml: fix default namespace of tags
b69ea01 encoding/xml: fix namespaces in a>b tags
3be158d encoding/xml: encoding name spaces correctly
and adjusts tests from
a9dddb5 encoding/xml: add more EncodeToken tests.
to expect Go 1.4 behavior.
I have confirmed that the name space parts of the test suite
as of this CL passes against the Go 1.4 encoding/xml package,
indicating that this CL successfully restores the Go 1.4 behavior.
(Other tests do not, but that's because there were some real
bug fixes in this cycle that are being kept. Specifically, the
tests that don't pass in Go 1.4 are TestMarshal's NestedAndComment
case, TestEncodeToken's encoding of newlines, and
TestSimpleUseOfEncodeToken returning an error for invalid
token types.)
I also checked that the Go 1.4 tests pass when run against
this copy of the sources.

Currently TestDoDupSuppress can fail if the goroutines created by its
loop run sequentially. This is rare, but it has caused failures on the
dashboard and in stress testing.
While I think there's no way to eliminate all possible thread
schedules that could make this test fail because it depends on waiting
until a Group.Do blocks, it is possible to make it much more robust.
This commit deflakes this test by forcing at least one invocation of
fn to start and all goroutines to reach the line just before the Do
call before allowing fn to proceed. fn then waits 10 milliseconds
before returning to allow the goroutines to pass through the Do.
With this change, in 50,000 runs of the stress testing configuration,
the number of calls to fn never even exceeded 1.

Besides formatting a parsed Address, the ParseAddress function also

received a signal, and os/signal.Notify was not being used to check
for occurrences of the signal, the signal was ignored.
This changes the code so that if os/signal.Notify is not being used,
then the signal handler is reset to what it was, and the signal is
raised again. This lets non-Go threads handle the signal as they
wish. In particular, it means that a segmentation violation in a
