This fixes a number of issues: * Zip archives with "length at end" can now be extracted correctly, since the Zip extractor can simply mark the size as "unknown." * Extract-to-disk can now accurately handle cases with partial time information (e.g., mtime is known but not atime) * We get more accurate handling of different hardlink extraction cases; sometimes a hardlink entry has definitive size information and sometimes not.

(Previously, it would return a zero-length block, then EOF, which elicited bogus warnings from bsdtar.) Also, correct the EOF return to correctly identify EOF as part of an empty block at the correct offset.

Change this so it returns NULL in that case, and update all of its callers to handle the error. Some of those callers can now return errors back to the client instead of calling exit(3).
