  1. Fix infinite loop when scanning some DMG archives 

    When decompressing a zlib stream, it's possible to reach end of stream
before running out of available bytes. In the DMG parser, this may cause
an infinite loop.

This commit adds a check for the condition where stream has ended before
running out of input.

Fixes: Cisco-Talos#925
