Subject: notifier: switch to QLIST
X-Git-Tag: TizenStudio_2.0_p2.3.2~208^2~4532
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=31552529a7eba5011dac74bab18a852860c45c9d;p=sdk%2Femulator%2Fqemu.git

notifier: switch to QLIST

Notifiers do not need to access both ends of the list, and using
a QLIST also simplifies the API.
