In a recent commit, pack-objects learned support for the
'pack.preferBitmapTips' configuration. This patch prepares the
multi-pack bitmap code to respect this configuration, too.
Since the multi-pack bitmap code already does a traversal of all
references (in order to discover the set of reachable commits in the
multi-pack index), it is more efficient to check whether or not each
reference is a suffix of any value of 'pack.preferBitmapTips' rather
than do an additional traversal.
Implement a function 'bitmap_is_preferred_refname()' which does just
that. The caller will be added in a subsequent patch.
