[PATCH 3/5] Cleanup unpack_entry_gently and friends to use type_name array.

[Shawn Pearce <spearce@spearce.org>]

[PATCH 3/5] Cleanup unpack_entry_gently and friends to use type_name array.

This change allows combining all of the non-delta entries into a
single case, as well as to remove an unnecessary local variable
in unpack_entry_gently.
