What's Changed

• Remove android specific code path for getting all addresses. by @rtibbles in #16

Full Changelog: 0.19.16...0.19.17

• Fix issue preventing TXT record updates from ServiceBrowser

• Track all requested broadcast interfaces in addition to those successfully attached

• Converts some usage of assert that should likely persist if python -O is used
• Breaks out interface attachment from Zeroconf.init into its own method _add_interfaces
• Adds corresponding behavior for removing interfaces, along the lines of how _add_interfaces functions but in reverse
• Exposes new public method Zeroconf.update_interfaces which triggers add or removal of interfaces
• Prevents stack trace reporting of errors that occur because the network is unreachable, errno.ENETUNREACH
• Updates Zeroconf.send to accept an interface on which filter the interfaces it sends the messages on, such that adding and removing interfaces can attempt to send add/remove messages when the interface is removed
