Subject: opkg: apply "2-pkg-vec--Optimize-gross-inefficiency.patch" from OpenEmbedded

  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.
