Subject: pbutils: GST_EXPORT -> GST_PBUTILS_API
X-Git-Tag: 1.19.3~511^2~1802
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=cad9759e7ba045b36b185fd0827e96c14228e9c6;p=platform%2Fupstream%2Fgstreamer.git

pbutils: GST_EXPORT -> GST_PBUTILS_API

We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.
