Define const array 'pseudorefs' with the names of the pseudorefs that
are documented in gitrevisions.1, and add functions for_each_pseudoref()
and refs_for_each_pseudoref() for iterating over them.
The functions process the pseudorefs in the same way as head_ref() and
refs_head_ref() process HEAD, invoking an each_ref_fn callback on each
pseudoref that exists.
This is in preparation for adding pseudorefs to log decorations.
