As part of #42026, these helpers from io/ioutil were moved to os.
(ioutil.TempFile and TempDir became os.CreateTemp and MkdirTemp.)
Update the Go tree to use the preferred names.
As usual, code compiled with the Go 1.4 bootstrap toolchain
and code vendored from other sources is excluded.
ReadDir changes are in a separate CL, because they are not a
simple search and replace.
For #42026.

The extend information of a time zone file with last transition < now

This could lead to wrong zones in systems with slim zoneinfo.

Follow-up for CL 261363 which had to retain the fat tz data format due
to failing test.
The reason for the failed tests was that when caching location data, the
extended time format past the end of zone transitions was not
considered. The respective change was introduced in (*Location).lookup
by CL 215539.
This slims down zoneinfo.zip (and thus also the embedded copy in
time/tzdata) by ~350KB.

Importing the time/tzdata package will embed a copy of the IANA
timezone database into the program. This will let the program work
correctly when the timezone database is not available on the system.
It will increase the size of the binary by about 800K.
You can also build a program with -tags timetzdata to embed the
timezone database in the program being built.
This is a roll forward of CL 224588 which was rolled back due to
test failures. In this version, the test is in the time package,
not the time/tzdata package. That lets us compare the zip file
to the time/tzdata package, ensuring that we are looking at similar
versions of tzdata information.

Currently, when a tz file was being checked inside a zoneInfo dir,
a syscall.ENOENT error was being returned, which caused it to look
in the zoneinfo.zip file and return an error for that case.
We return a syscall.ENOENT error for the zip file case too, so that
it falls through to the end of the loop and returns an uniform error
for both cases.

Loading location data from tzdata files was only supported
from default paths on android. This change enables support on
all OS via the ZONEINFO environment variable and reduces the
amount of android specific code significantly.
Furthermore, unsuccessful calls to LoadLocation now return the
first error encountered, including errors from attempting to
load a location from the source specified by ZONEINFO.
Errors indicating that the source or location was not found are
ignored until all possible sources have been traversed.

The time package has never depended on the io package until
a recent change during Go 1.7 to use the io.Seek* constants.
The go/build dependency check didn't catch this because "time" was
allowed to depend on meta package group "L0", which included "io".
Adding the "io" package broke one of Dmitry's tools. The tool is
fixable, but it's also not necessary for us to depend on "io" at all
for some constants. Mirror the constants instead, and change
deps_test.go to prevent an io dependency in the future.
