Avoid including clog.h in proc.h

Browse source 
The number of .c files that must include access/clog.h can currently be
counted on one's fingers and miss only one (assuming one has the usual
number of hands).  However, due to indirect inclusion via proc.h,
there's a lot of files that are pointlessly including it.  This is easy
to avoid with the easy trick implemented by this commit.
