pkg_vec: Optimize gross inefficiency.
This module tries to implement *unique* vector (without duplicating objects),
and does this by iterating thru all already existing elements. Thus,
complexity of adding N elements was O(N^2). However, there're no grave reasons
to do uniqueness at all:
1. First of all, if feeds are correct, there won't be duplicates.
2. Then, even if there will be, there won't be serious problems like
segfaults.
3. Finally, for quite a few operations vectors is constructed from a
hashtable, thus uniqueness is guaranteed (which reduces possible cases of
non-uniqueness to values of Depends: and friends).
All an all, remove dup check, and make ipkg work order of magnitude faster on
a feed with few thousands of packages.
