This currently has no effect, as there are no quotable characters
inside it, but it will allow us to send embedded keys through to
the method.

Add a new Item field called FetchAfter, which determines the earliest
time the item should be fetched at. Adjust insertion into queue to
take it into account alongside priority, and only fill pipelines
with items that are ready.

<title>pkgAcqIndex::CommonFailed: Set StatIdle before calling Init()</title>

Enqueuing by calling Init(), and then resetting the status to
idle means that the item can get enqueued twice if we call
Cycle() from inside pkgAcquire::Run().

Reset the status to StatIdle before calling Init()

<title>Use full item description in broken repo error</title>

The error says the repository is broken but doesn't mention which one it
is. The item description gives us at least all the information, but is
not as nicely formatted. As this message is not even marked for
translation this is a rather temporary affair and we can survive without
the eye candy for a while.

<title>URI encode Filename field of Packages files (again)</title>

Keeping URIs encoded in the acquire system depends on having them
encoded in the first place. While many other places got the encoding
2 out of 3 ArchiveURI implementations were missed which are in practice
responsible for nearly all of the URI building, just that index filename
do not contain characters to escape and the Filename fields in Packages
files usually aren't. Usually. Except if you happen to have e.g. an epoch
featuring package with the colon encoded in the filename. On the upside,
in most repositories the epoch isn't part of the filename.

Enable the Acquire::Retries option by default, set to 3.
This will help with slightly unreliable networking; future
work is needed for adding backoff and SRV/IP rotation.

<title>Error on packages without a Size field (option Acquire::AllowUnsizedPackages)</title>

<content type='text'>
Repositories without Size information for packages are not
proper and need fixing. This ensures people see an error in
CI, and get notifications and hence the ability to fix it.

It can be turned off by setting Acquire::AllowUnsizedPackages
to true.

The mirror method can distribute requests for files based on various
metadata bits, but some – the main index files – weren't actually
passing those on to the methods as advertised in the manpage.

This is hidden both by mirror usually falling back to other sources
which will eventually hit the right one and that if the repository does
not support by-hash apt will automatically stick to the mirror which was
used for the Release file.

<title>Start pdiff patching from the last possible starting point</title>

Especially in small sections of an archive it can happen that an index
returns to a previous state (e.g. if a package was first added and then
removed with no other changes happening in between). The result is that
we have multiple patches which start from the same hash which if we
perform clientside merging is no problem although not ideal as we
perform needless work.

For serverside merging it would not matter, but due to rred previously
refusing to merge zero-size patches but dak ignoring failure letting it
carry these size-zero patches until they naturally expire we run into a
problem as these broken patches won't do and force us to fall back to
downloading the entire index. By always starting from the last patch
instead of the first with the starter hash we can avoid this problem
and behave optimally in clientside merge cases, too.
