[Yum-devel] [PATCH 5/5] Add optimized simplePkgList() to sqlitesack, significant speedup:

[James Antill]

 This is what the above few patches were for, as this function now just
calls them.

 Speed differences on my machine:

time (echo | yum update wodim)
 Before: 8.0 seconds
 After:  6.5 seconds (81.25%)

time yum check-update
 Before: 3.9 seconds
 After:  2.5 seconds (64.10%)
