Several fixes for building debug versions of NX (990_fix-DEBUG-and-TEST-builds.full.patch).

  (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.
