flags: add lists of flags called Client and Server

Simplifies initializing Upspin programs and also makes it easier
long-term to manage the flags package.

Change the signature of flags.Parse to accept a default list
along with any extras.

Remove "storeserveruser" from the flags package. It's only used in
one place.

Update all programs.

Fixes #349.
