The point of this file was to be easily usable by applications that want
to generate capture files (or proxy them). The intention here is that we
only have SpCaptureReader/SpCaptureWriter (and associated bits necessary
to support that).
This makes sure that we do not use GObject from the libsysprof-capture-2.a
while still having GType's in the libsysprof-2.so dynamic library.
We also invert the GObject macro check so that the default is to not
register a GType which increases the chances that copy/paste code does
not run into double-registering a GType if used with an application that
links against libsysprof-2. (One such example could be if Gtk uses this
code for timers, as it would break Sysprof itself).
The lib/ directory was getting a bit out of hand, so this tries
to organize things a bit so it is easier going forward to locate
the code people want to patch.
