 Creating and freeing a hash table
 ---------------------------------
 
    To create a hash table, create an instance of a `struct
 bfd_hash_table' (defined in `bfd.h') and call `bfd_hash_table_init' (if
 you know approximately how many entries you will need, the function
 `bfd_hash_table_init_n', which takes a SIZE argument, may be used).
 `bfd_hash_table_init' returns `false' if some sort of error occurs.
 
    The function `bfd_hash_table_init' take as an argument a function to
 use to create new entries.  For a basic hash table, use the function
 `bfd_hash_newfunc'.   Deriving a New Hash Table Type, for why
 you would want to use a different value for this argument.
 
    `bfd_hash_table_init' will create an objalloc which will be used to
 allocate new entries.  You may allocate memory on this objalloc using
 `bfd_hash_allocate'.
 
    Use `bfd_hash_table_free' to free up all the memory that has been
 allocated for a hash table.  This will not free up the `struct
 bfd_hash_table' itself, which you must provide.
