    libafs: Implement unixuser RW locks
    
    Currently code dealing with changing unixuser structs does not obtain
    any locks protecting the contents of the unixuser struct, though some
    functions like afs_GetUser have a parameter indicating what type of
    lock should be obtained. This can result in the token data for a user
    being changed at the same time another thread tries to use the token
    data.
    
    To ensure mutual exclusion of such operations, add a lock field to the
    unixuser struct, and actually lock it according to the intentions of
    the relevant code.
