No, you should clone from upstream. http://anongit.freedesktop.org/git/spice/spice-common.git/
However, you'll need to change this in spice-protocol:

--- a/spice/qxl_dev.h
+++ b/spice/qxl_dev.h
@@ -277,6 +277,7 @@ typedef struct SPICE_ATTR_PACKED QXLRam {
 typedef union QXLReleaseInfo {
     uint64_t id;      // in
     uint64_t next;    // out
+    void *data;
 } QXLReleaseInfo;

No idea, this page seems to have a lot of entry point for system profiling:
http://dtrace.org/blogs/brendan/2013/09/18/the-use-method-mac-os-x-performance-checklist/

then there are some specific macosx tools, like opengl profiler (I don't know if gtk/cairo uses opengl indirectly on mac)
