Add an option to emit extra debug code in the generated protocol functions.

Browse Source 
The debug version of indirect.c has proven very helpful during the
development of new client-side and server-side GLX protocol code.  This is
put here instead of in the DISPATCH and DISPATCH_RETURN macros in dispatch.c
for two reasons.

1. I only want the debug information when indirect-rendering is used.

2. Functions that require a reply from the server, some of which do not have
a return value (e.g., glFlush, glFinish, glGetLightfv, etc.), do not need
the extra glFinish call.
