This changeset fixes how some digitalocean dns records were getting
parsed. In particular, it allows for understanding "@" as shorthand for
the domain itself, preventing terraform from suggesting changes that
wouldn't have any actual effect. This changeset also adds a trailing "."
to certain record types which are required to be submitted with a
trailing dot, but which digitalocean does not return with a trailing
dot, again preventing changes that wouldn't have an effect.
Tests have been added for the above, and with just adding the tests, the
current code is failing, as it is handling some records(e.g. MX)
incorrectly
Fixes failing acceptance test:
```
$ make testacc TEST=./builtin/providers/digitalocean TESTARGS='-run=TestAccDigitalOceanVolume_Droplet'
==> Checking that code complies with gofmt requirements...
go generate $(go list ./... | grep -v /terraform/vendor/)

--- PASS: TestAccDigitalOceanVolume_Droplet (57.38s)
PASS
ok github.com/hashicorp/terraform/builtin/providers/digitalocean 57.411s
```
Also removes all redundant type declarations in the digitalocean package.
The error string for 404s on DNS domains has (apparently)
changed, causing things to be a little sad when you modify
DNS domains from the DO console instead of terraform. This
is just the same fix as was applied to droplets around this
time last month.
While I was at it I just fixed this everywhere I saw it in the
DO provider source tree.
