nx-X11/programs/Xserver/Imakefile: Don't overlink nxagent. Linking against libXrandr and libXtst is not necessary for nxagent.

Fixes ArcticaProject/nx-libs#110.

nx-X11/config/cf/lnxLib.tmpl requires post-library removal cleanup: Drop references to dropped X11 extension client libraries.

Fixes ArcticaProject/nx-libs#115.

  Plus: Drop various Imake'ish defines where not needed anymore.

Fix debugging function for Loop.cpp. getDebugSpec was replaced by << operand in ChannelEndPoint.{h|cpp}, fixes #130

nx-X11/programs/Xserver/{hw/nxagent/NX,render/}picture.c: add and use new function ReduceCompositeOp().

More or less just an optimization for more "trivial" composite operations
requiring less work, but syncs up the newer X.Org Server and nx-libs a bit
more.

nx-X11/programs/Xserver/composite/Imakefile: add new file to SRCS and OBJS and define -DNXAGENT_SERVER while building the Composite extension to disable some code that depends upon a newer X.Org architecture.

misc nx-X11/{programs/Xserver/composite,include/extensions}: update to Composite 0.4 - with changes where neccessary and rough edges.
