Xcode Project Needs Updating

It would be nice to be able to use Xcode to work on Issue 847, but 
gears/tools/osx/gears.xcodeproj/project.pbxproj hasn't been updated since 
r2827, and won't build without 
errors.

I've attached a patch for fixes the build errors.  For future reference, it was 
helpful to do the following things:

Reinstall Xcode, since the Mac OS X 10.4 SDK is not included by default in the 
Snow Leopard Developer Tools.

Switch the project compiler from the system default (GCC 4.2, which won't work 
with the 10.4 SDK) to GCC 4.0.

Update Xcode's view of the project's files to match the changes in the 
gears/Makefile between r2827 and r3414.

Patch /usr/include/curl/curl.h, because gears/base/safari/curl_downloader.mm  
#includes 
/usr/include/curl/curl.h, which results in a build error 
"/usr/include/curl/curl.h:35:66: error: curl/curlbuild.h: No 
such file or directory."  Editing curl.h to remove the extra directory fixes 
this issue.  The cURL project's log for 
curl.h at 
<http://curl.haxx.se/cvs.cgi/curl/include/curl/curl.h?r1=1.397&view=log> shows 
a series of changes 
to this line between revisions 1.391 and 1.397, so hopefully Apple will 
eventually pick up the change.

Add SystemConfiguration.framework to the Gears.bundle target to supply some 
undefined _kSC symbols.

Recreate the sqlite_google folder groups, so as to be independent of the 
underlying filesystem.

Create a new target for skia, since it has been compiled from scratch since 
r3205, rather than just linking in a 
pre-compiled version.  Then, add the skia target as a prerequisite for the 
Gears.bundle target, add libskia.a to 
the libraries that are linked into Gears.bundle, and remove the old skia linker 
flags.  This eliminates linking errors 
about not finding the skia-dbg-osx-i386+ppc library.  The Gears.plugin target 
also has a -lskia-dbg-osx-
i386+ppc, flag set, but changing it to -lskia should fix it.  Finally, set the 
skia target's visibility options to hidden 
to eliminate some linker warnings about symbol visibility.

Add a user header search path of $(SRCROOT)/../../../third_party/zlib to 
libpng, so that it will include zlib.h from 
the project, rather than /usr/local/include.  This eliminates linker errors 
about undefined symbols in pngread.

Remove the sqlite target's SQLITE_OMIT_ATTACH flags, since parse.c in r3145 was 
generated with ATTACH 
enabled.  This fixes linker errors about undefined attach, detach, and vacuum 
symbols in libsqlite's parse file.
