Bug#632668: apt-key: does not look at apt.conf for all gpg files

[dirson@debian.org]

Package: apt
Version: 0.8.10.3+squeeze1
Severity: wishlist

apt-key hardcodes several paths which belong to the apt config, at least:
/etc/apt/secring.gpg
/etc/apt/trustdb.gpg

There are also references to /var/lib/apt/keyrings which are probably in the same
situation.

Not a patch (and would probably require -o support as well for my use case), but I could get
"add" to work for me with:

$ diff -u /usr/bin/apt-key .

And apt-get -o Dir::Etc=$PWD/etc is (at last) happy after that.
