/*
* Data structure here is as follows:
*
* For each package we have a ‘struct fsys_namenode_list *’, the head of a list of
* files in that package. They are in ‘forwards’ order. Each entry has a
* pointer to the ‘struct fsys_namenode’.
*
* The struct fsys_namenodes are in a hash table, indexed by name.
* (This hash table is not visible to callers.)
*
* Each fsys_namenode has a (possibly empty) list of ‘struct filepackage’,
* giving a list of the packages listing that filename.
*
* When we read files contained info about a particular package we set the
* ‘files’ member of the clientdata struct to the appropriate thing. When
* not yet set the files pointer is made to point to ‘fileslist_uninited’
* (this is available only internally, within filesdb.c - the published
* interface is ensure_*_available).
