Tim Kientzle aee47dd7c8 More work on ACLs: fix error in archive_entry's ACL parsing code,
try to set ACLs even if fflag restore fails, first cut at reading
  Solaris tar ACLs

Code improvement: merge gnu tar read support into main tar reader;
  this eliminates a lot of duplicate code and generalizes the tar
  reader to handle formats with GNU-like extensions.

Style: Makefile cleanup, eliminate 'dmalloc' references, remove 'tartype'
  from archive_entry (this makes archive_entry more format-agnostic)

Thanks to: David Magda for providing Solaris tar test files
