For example, unique([1,2,3,1,2,3]) is some permutation of [1,2,3],
unique("abcabc") some permutation of ["a", "b", "c"], and
unique(([1, 2], [2, 3], [1, 2])) some permutation of
[[2, 3], [1, 2]].
For best speed, all sequence elements should be hashable. Then
unique() will usually work in linear time.
If not possible, the sequence elements should enjoy a total
ordering, and if list(s).sort() doesn't raise TypeError it's
assumed that they do enjoy a total ordering. Then unique() will
usually work in O(N*log2(N)) time.
If that's not possible either, the sequence elements must support
equality-testing. Then unique() will usually work in quadratic
time.

Return if the GPG key described by the given keyid and timestamp are
installed in the rpmdb.
The keyid and timestamp should both be passed as integers.
The ts is an rpm transaction set object
Return values:
- -1 key is not installed
- 0 key with matching ID and timestamp is installed
- 1 key with matching ID is installed but has a older timestamp
- 2 key with matching ID is installed but has a newer timestamp
No effort is made to handle duplicates. The first matching keyid is used to
calculate the return result.
