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.

`filters.ToParam()` and `filters.FromParam()` were deprecated in favor of
`filters.ToJSON()` and `filters.FromJSON()` in 065118390a,
but still used in various locations.
This patch replaces uses of `filters.ToParam()` and `filters.FromParam()` with
`filters.ToJSON()` and `filters.FromJSON()`.

The Docker CLI already performs version-checks when
running commands, but other clients consuming the API
client may not do so.
This patch adds a version check to various
client functions.
