This fix avoids the warning "comparison between signed and unsigned
integer expressions [-Wsign-compare]". The index for the loop
needs to be unsigned for compare with globbuf.gl_pathc structure
member.
In the meantime the package was updated to remove the old APT manpages
from this package, so we can now add a Breaks and version it, too.
The intial Replaces was added in:

Partial upgrades…
The fix for 704608 assumes that bf35c19b81
was applied to libapt-inst which isn't the case for partial upgrades of
course, so break it to ensure that it is the case.

This adds ::InfoFD option alongside the ::Version one to request sending
the information to the specified FD, by default it is STDIN as it was
the case before.
The environment variable APT_HOOK_INFO_FD contains the FD the data is on as
a confirmation that the APT version used understood the request.
Allowing the hook to choose the FD is needed/helpful e.g. for shellscripts
which have a hard time accessing FDs above 9 (as >= 10 are usually used
internally by them)

We don't need initialized memory for pkgTagFile, but more to the point
we can use realloc this way which hides the bloody details of increasing
the size of the buffer used.

In 91c4cc14d3 I removed the +256 from
the pkgTagFile call parsing Release files as I couldn't find a
mentioning of a reason for why and it was marked as XXX which suggested
that at least someone else was suspicious.
It turns out that it is indeed "documented", it just didn't found it at
first but the changelog of apt 0.6.6 (29. Dec 2003) mentions:
* Restore the ugly hack I removed from indexRecords::Load which set the
pkgTagFile buffer size to (file size)+256. This is concealing a bug,
but I can't fix it right now. This should fix the segfaults that
folks are seeing with 0.6.[45].
The bug it is "hiding" is that if pkgTagFile works with a file which doesn't
end in a double newline it will be adding it without checking if the Buffer
is big enough to store them. Its also not a good idea to let the End
pointer be past the end of our space, even if we don't access the data.

In bugreport deb:719629 Paul Wise mentions both to enable some malloc
checks and as more testing can't hurt we enable both for all testcases.

If we are called by make everything is build already and
so this is just a noise nop we can just skip.
(Noisy as it complains about being unable to communicate with
the other makes to coordinate with the jobserver)

The debian-archive-keyring package ships trusted.gpg.d fragment files
for a while now and dropped their call to 'apt-key update', so there is
no need for use to call it as the keys will always be available.
This also finally allows a user to remove key(ring)s without APT to
overriding this decision by readding them with this step.
The functionality is kept around in the odd case that an old
debian-archive-keyring package is used which still calls 'apt-key
update' and depends on the import (hence, we also do not enforce a newer
version of the debian-archive-keyring via our dependencies)
Having fragement files means there is a good chance that there is one
key per keyring, so deal with that as well as with setups in which
keyrings are linked into trusted.gpg.d as we can't just modify those
files (they might be in /usr for example).
for some "interesting" reason gpg decides that it needs to update its
trustdb.gpg file in a --list-keys command even if right before gpg is
asked to --check-trustdb. That wouldn't be as bad if it wouldn't modify
the keyring being listed at that moment as well, which generates not
only warnings which are not a problem for us, but as the keyring
modified can be in /usr it modified files which aren't allowed to be
modified.
The suggested solution in the bugreport is running --check-trustdb
unconditionally in an 'apt-key update' call, but this command will not
be used in the future and this could still potentially bite us in
net-update or adv calls. All of this just to keep a file around, which
we do not need…
The commit therefore switches to the use of a temporary created
trusted.gpg file for everyone and asks gpg to not try to update the
trustdb after its intial creation, which seems to avoid the problem
altogether.
It is using your also faked secring btw as calling the check-trustdb
without a keyring is a lot slower …
Closes: #687611
Thanks: Andreas Beckmann for the initial patch!
APT doesn't care for the trustdb.gpg, but gnupg requires one even for
the simplest commands, so we either use the one root has available in
/etc or if we don't have access to it (as only root can read that file)
we create a temporary directory to store a trustdb.gpg in it.
We can't create just a temporary file as gpg requires the given
trustdb.gpg file to be valid (if it exists), so we would have to remove
the file before calling gnupg which would allow mktemp (and co) to hand
exactly this filename out to another program (unlikely, but still).
Usually, most apt-key commands require root, so the script is checking
for being run as root, but in your tests we use a non-root location, so
we don't need to be root and therefore need an option to skip the check.

While we don't want these error messages on our usual stack, we can use
our usual infrastructure to generate an error message with all the usual
bells like errno and strerror attached.

If this code is run as non-root we are in a special situation (e.g. in
our testcases) where it is obvious that we can't enforce user/group on
any file, so skip this code altogether instead of bugging users with
an error message – which we also switch to a warning as a failure to
open the file is "just" a warning, so the 'wrong' owner shouldn't be
that much of an issue.
The file is still handled with chmod, so all the security we can enforce
is still enforced of course, which also gets a warning if it fails.
