[webkit-gtk] Possible minor WebKitAutocleanups.h regression in v2.16.1 release

[Robert Bisewski]

Hi,

I was attempting to compile my webkit2-based browser `sighte` using the
new v2.16.1 release of webkit2-gtk when I noticed the following warning
from my gcc v6.3.0 compiler:

/usr/include/webkitgtk-4.0/webkit2/WebKitAutocleanups.h:83:77: 
warning: ISO C does not allow extra ‘;’ outside of a function
[-Wpedantic] G_DEFINE_AUTOPTR_CLEANUP_FUNC (WebKitWebsiteData, 
webkit_website_data_unref);

This is no means a hold up for my project, but the warning did not
appear before, so I figured taking a bit of time to track down exactly
what was causing it would be in order.

While I am not exactly well-versed at your code base, just glancing
quickly from Trac leads me to believe that the specific commit appears
to be this one:

https://trac.webkit.org/changeset/214163/webkit

Simply removing the aforementioned ; character from the file
WebKitAutocleanups.h on line 83 seems to resolve the warning in
question.

If adding the semi-colon is not intended, then I hope you find this
helpful :)
