Parallel installs

[Owen Taylor <otaylor redhat com>]

Thinking about the issue of parallel installs of GTK+-1.2 and GLib-1.2
today, it seems to me:

 - We need to definitely support parallel user installs
   for average users, and supporting parallel devel
   installs for average developers would be nice too.

 - Using a separate prefix is not the right solution
   for the user installs and is not a great solution
   for developer installs.

   While a person installing GTK+ from scratch can 
   use a different prefix for different versions, this
   is not an attractive solution for people making
   packages for distributions, especially when they
   are trying to remain FHS compliant. 

   Also, using different prefixs means juggling $PATH
   to get the correct compilation

So, I propose the great move:

 /usr/include/glib.h => /usr/include/glib2/glib.h
 /usr/lib/glib/include => /usr/lib/glib2/include
 /usr/lib/glib/libglib.so => /usr/lib/glib/libglib-{1-3,2-0}.so
 glib-config => glib2-config

 /etc/gtk => /etc/gtk2
 /usr/share/local/*/*/gtk+.mo => /usr/share/local/*/*/gtk2.mo
 /usr/share/themes/*/gtk/ => /usr/share/themes/*/gtk2/
 /usr/include/gtk => /usr/include/gtk2/gtk
 /usr/include/gdk => /usr/include/gtk2/gdk
 gtk-config => gtk2-config

And anything else that can conflict. Basically, you should be able to
install both runtime and devel packages at once without a single
conflict.
