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
