Reorganize/rename unpack_non_delta_entry to unpack_compressed_entry.

This function was moved above unpack_delta_entry so we can call it
from within unpack_delta_entry without a forward declaration.

This change looks worse than it is.  Its really just a relocation
of unpack_non_delta_entry to earlier in the file and renaming the
function to unpack_compressed_entry.  No other changes were made.
