[bitbake-devel] [PATCH 11/12] Hob: improve recipe/package selection performance

[Dongxiao Xu]

Originally we will send selection chagned notification in each
include_item and exclude_item, which is time cost since these are
recursive functions and we may select hundreds of recipes/packages.

The improvement is to move the notification from include_item and
exclude_item to the place where the two functions are called.
This could greatly improve the selection/deselection speed for recipe
and package lists.
