RootHelper 1.8.0

• Added support for testing compressed archives, and extracting multiple archives at once
• Use select for monitoring both local and accept socket in xre server (this makes possible to avoid registering atExit routines in forked xre child)
  Misc fixes on:
  • TLS connection management; added timeouts on both connection setup and shutdown
  • https client
  • directory hashing under Windows (both content-only and with-names hashing)
  • listing/extracting/testing some archives with malformed headers (specifically, recent APK archives, which contain one entry which is the empty string)
