Support by-hash index files in apt-cacher-ng

[Stefan Bader]

Server side by-hash index files are a new feature that was introduced in Xenial. This causes Xenial clients (apt) to start new pattern requests which apt-cacher-ng needs to be aware of. For Xenial's version of apt-cacher-ng this was already done.

SRU Justification (for backports):

Impact: Another new feature of the archive in Xenial is server side by-hash index files. To support this when running through an apt-cacher-ng proxy requires another modification to be backported into older releases.

Fix: TBD (pick the pattern modification and apply it to older releases).

Testcase: Running "apt-get update" on a Xenial host causes error messages like below in the log of apt-cacher-ng on the proxy host.

This is the change added to Xenial modified to apply against Wily (only context fixup).

Thanks for preparing this fix. I can confirm that the version of apt-cacher-ng in trusty-proposed (0.7.26-1ubuntu0.1) permits the downloading and caching of the by-hash indexes. I'm also able to install and update packages via this version of apt-cacher-ng as before, both for hosts running xenial and for hosts running older ubuntu releases. Marking verificaition-done for trusty.
