Reviewed by Martin Robinson.

.:

* GNUmakefile.am: Initialize pkgconfigdir and pkgconfig_DATA which
are common to all libraries.
* configure.ac: Update pkg-config files.

Source/JavaScriptCore:

* GNUmakefile.am:
* javascriptcoregtk.pc.in: Renamed from Source/WebKit/gtk/javascriptcoregtk.pc.in.

Source/WebKit/gtk:

* GNUmakefile.am: Remove javascriptcore pc file references.

Source/WebKit2:

* GNUmakefile.am: Rename pc file as webkit2gtk.pc.in. WebKit2
depends on gtk3 unconditionally so we don't need to use
WEBKITGTK_PC_NAME.
* webkit2gtk.pc.in: Renamed from Source/WebKit2/gtk/webkit2.pc.in.
