A new envrionment variable GNOME_SHELL_ENABLE_CLEANUP is added which
causes us to attempt freeing global data. The reason this isn't
enabled by default is that it's a waste of time at best, and at
worst in corner cases could cause crashes which would fill up
crash databases. Better to leave it as a developer-only tool.
Start stubbing out some cleanup in ShellGlobal.

We weren't specifying _ALLOW_REPLACEMENT for anything except
org.gnome.Shell, which created a race - if the exiting process
didn't exit fast enough, the replacing process would fail
to get the name.

Previously (because I suck) we were ignoring the return value of
RequestName, and so we'd totally ignore the fact that we failed
to acquire the DBus name.
Make this consistent by using meta_get_replace_current_wm() and
if we're in --replace, actually replace immediately.

Build gnome-shell as a binary linked against libmutter-wm, instead of
a module to be loaded by libmutter-wm. Move the majority of
initialization-type stuff from gnome_shell_plugin_start() into main().
We still build libgnome-shell as a shared library, so that the linker
doesn't discard all the methods that are never called from C.
