When dialing with a relative Timeout instead of an absolute Deadline,
the deadline function only makes sense if called before doing any
time-consuming work.

This change calls deadline exactly once, storing the result until the
Dial operation completes.  The partialDeadline implementation is
reverted to the following patch set 3:
https://go-review.googlesource.com/#/c/8768/3..4/src/net/dial.go

Otherwise, when dialing a name with multiple IP addresses, or when DNS
is slow, the recomputed deadline causes the total Timeout to exceed that
requested by the user.

Fixes #11796

This is needed to handle vendor directories correctly.  It was already
done for the regular imports when the package was loaded, but not for
the test-only imports.

It would be nice to do this while loading the package, but that breaks
the code that checks for direct references to vendor packages when
running go test.  This change is relatively contained.

While we're at it, skip "C" test imports in go get.

Updated Address.String so it restores quoted local parts, which wasn't
done before.
When parsing `<" "@example.com>`, the formatted string returned
`< @example>`, which doens't match RFC 5322, since a space is not atext.
Another example is `<"bob@valid"@example.com>` which returned
`<bob@valid@example.com>`, which is completely invalid.
I also added support for quotes and backslashes in a quoted local part.

Besides formatting a parsed Address, the ParseAddress function also
needed more testing and finetuning for special cases.
Things like `<.john.doe@example.com>` and `<john..doe@example.com>`
e.a. were accepted, but are invalid.
I fixed those details and add tests for some other special cases.

In the past badsignal would crash the program.  In
https://golang.org/cl/10757044 badsignal was changed to call sigsend,
to fix issue #3250.  The effect of this was that when a non-Go thread
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
non-Go thread will ordinarily crash the process, as it should.

JSON decoding currently fails for null values bound to any type
which does implement the JSON Unmarshaler interface without checking
for null values (such as time.Time).

It also fails for types implementing the TextUnmarshaler interface.

The expected behavior of the JSON decoding engine in such case is
to process null by keeping the value unchanged without producing
any error.

Make sure null values are handled by the decoding engine itself,
and never passed to the UnmarshalText or UnmarshalJSON methods.
