    Linux: Make keyring destructor remove all tokens
    
    The keyring destructor on Linux was only destroying the first
    unixuser structure found for the PAG being destroyed. In environments
    where each PAG contains tokens for multiple cells, this led to us
    leaking unixuser structures, and eventually grinding to a hault due
    to the length of the resulting hash chains (and some horrific
    O(n-squared) performance in the PAG statistics code).
    
    Add a utility function for the keyring destruction function to call
    which will mark as deleted all unixuser structures for a particular
    PAG, and use it.
