When mac integration or binary relocation are disabled, the compiled
object file contains no symbols because the guards in the source files
hide all code. On OS X there's a warning during compilation saying:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib:
file: .libs/libgeany.a(libgeany_la-prefix.o) has no symbols
If these features are disabled, don't compile the corresponding
sources to avoid the warnings.
Interestingly, waf compilation works without warnings - it appears
linking is done through g++ which doesn't produce these warnings.
This patch adds the gtk-mac-integration library and uses it to
adjust various paths in Geany to point it inside the app bundle
if Geany runs from inside the bundle.
It adds the utils_resource_dir() utility function to return
correct directories for various kinds of resources for all supported
operating systems. Using this function the patch adjusts all Geany
resource, plugin, icon, doc, and locale paths.
