Currently even if the command supports encrypted objects,
the syntax verification would fail on them in certain
cases. Since syntax validation of source/targets doesn't
use the parsed encrypt key pairs. This PR fixes this
behavior.
The probe package is no longer available in the Minio server
repo. This change just moves probe from the vendor directory to its
own dir under `pkg`.
This is a maintenance fix.
Previously it was failing like below.
```
$ mc ls --incomplete myminio/mybucket
[2016-09-16 09:48:57 PDT] 576MiB 1.iso
$ mc ls --incomplete myminio/mybucket/1.iso
mc: <ERROR> Unable to initialize target ‘myminio/mybucket/1.iso’. Object key is missing, object key cannot be empty
```
This patch fixes this issue.
