+The sha1-array API provides storage and manipulation of sets of SHA-1
identifiers. The emphasis is on storage and processing efficiency,
making them suitable for large lists. Note that the ordering of items is
not preserved over some operations.

+ A single array of SHA-1 hashes. This should be initialized by
assignment from `SHA1_ARRAY_INIT`. The `sha1` member contains
the actual data. The `nr` member contains the number of items in
the set. The `alloc` and `sorted` members are used internally,
