12b6083c8f Remove panic in nat package on invalid hostport
Closes #14621

This one grew to be much more than I expected so here's the story... :-)
- when a bad port string (e.g. xxx80) is passed into container.create()
  via the API it wasn't being checked until we tried to start the container.
- While starting the container we trid to parse 'xxx80' in nat.Int()
  and would panic on the strconv.ParseUint().  We should (almost) never panic.
- In trying to remove the panic I decided to make it so that we, instead,
  checked the string during the NewPort() constructor.  This means that
  I had to change all casts from 'string' to 'Port' to use NewPort() instead.
  Which is a good thing anyway, people shouldn't assume they know the
  internal format of types like that, in general.
- This meant I had to go and add error checks on all calls to NewPort().
  To avoid changing the testcases too much I create newPortNoError() **JUST**
  for the testcase uses where we know the port string is ok.
- After all of that I then went back and added a check during container.create()
  to check the port string so we'll report the error as soon as we get the
  data.
- If, somehow, the bad string does get into the metadata we will generate
  an error during container.start() but I can't test for that because
  the container.create() catches it now.  But I did add a testcase for that.

9c2374d196 Move /nat to /pkg/nat
By convention /pkg is safe to use from outside the docker tree, for example
if you're building a docker orchestrator.

/nat currently doesn't have any dependencies outside of /pkg, so it seems
reasonable to move it there.

This rename was performed with:

```
gomvpkg -vcs_mv_cmd="git mv {{.Src}} {{.Dst}}" \
	-from github.com/docker/docker/nat \
        -to   github.com/docker/docker/pkg/nat

```
