Unlike a plain `net/http/client.Do()`, requests made through client/request
use the `sendRequest` function, which parses the server response, and may
convert non-transport errors into errors (through `cli.checkResponseErr()`).
This means that we cannot assume that no reader was opened if an error is
returned.
This patch changes various locations where `ensureReaderClosed` was only
called in the non-error situation, and uses a `defer` to make sure it's
always called.
`ensureReaderClosed` itself already checks if the response's body was set,
so in situations where the error was due to a transport error, calling
`ensureReaderClosed` should be a no-op.

Since Go 1.7, context is a standard package. Since Go 1.9, everything
that is provided by "x/net/context" is a couple of type aliases to
types in "context".
Many vendored packages still use x/net/context, so vendor entry remains
for now.

ContainerExecAttach used `types.ExecConfig` instead of `types.ExecStartCheck`,
which is the type that's expected by the `/exec/execid/start` API endpoint.
Investigating when this inconsistency was introduced, I found that the client has
sent the additional properties since its first imlpementation in
c786a8ee5e.
The `postContainerExecStart()` at that time used the "jobs" package, which
only took the information from the body that was needed (`Detach` and `Tty`).
Commit 24425021d2 refactored the Exec commands
to remove the "jobs", and introduced the `ExecStartCheck` type, but failed to
update the `cli.hijack()` call with the new type.
The change in this patch should not affect compatibility with older clients,
as the additional information from the `ExecConfig` type is not used (the
API server already decodes to the `ExecStartCheck` type).
