			This is a mechanical clean-up of the way *.c files include
system header files.
 (1) sources under compat/, platform sha-1 implementations, and
     xdelta code are exempt from the following rules;
 (2) the first #include must be "git-compat-util.h" or one of
     our own header file that includes it first (e.g. config.h,
     builtin.h, pkt-line.h);
 (3) system headers that are included in "git-compat-util.h"
     need not be included in individual C source files.
 (4) "git-compat-util.h" does not have to include subsystem
     specific header files (e.g. expat.h).
