Description: Several fixes for building debug versions of NX
Abstract:
 (1) In nx-X11/programs/Xserver/dix:
 .
 Fix several compile errors when specifying -DDEBUG globally. Previous GCC
 versions were more liberal and the code thus compiled.
 .
 Also initialize/reset a count variable correctly.
 .
 .
 (2) In nx-X11/programs/Xserver/hw/nxagent/Render.c:
 .
 Check for pSrc->pDrawable to exist instead of having nxagent segfault when
 it does not.
 .
 This enables the possibility of compiling all nxagent modules in TEST mode.
