git passes a credential that has been used successfully to the helpers
to record. If a credential is already stored,
"git-credential-osxkeychain store" just records the credential returned
by "git-credential-osxkeychain get", and unnecessary (sometimes
problematic) SecItemAdd() and/or SecItemUpdate() are performed.
We can skip such unnecessary operations by marking a credential returned
by "git-credential-osxkeychain get". This marking can be done by
utilizing the "state[]" feature:
- The "get" command sets the field "state[]=osxkeychain:seen=1".
- The "store" command skips its actual operation if the field
"state[]=osxkeychain:seen=1" exists.
Introduce a new state "state[]=osxkeychain:seen=1".
