* begin adding tls
* remove incomplete line in gw/main.go
* identity fixes+:
+ fix `peertls.NewCert` public key issue
+ fix `peertls.verfiyChain` issue
+ fix identity dial option
+ rename `GenerateCA` to `NewCA` and `generateCAWorker` to `newCAWorker` for better consistency/convention
* use pdbclient instead of pointerdb in miniogw
* fix tests
* go fmt
* make review changes
* modify how context.Background() is used
* more context stuff
* pointerdb: separate client and server packages
the reason for this is so that things the server needs (bolt, auth)
don't get imported if all you need is the client. will result in
smaller binaries and less flag definitions
* review comments
