core: miscellaneous cleanup
clean up things that I tripped over doing other changes. 1) fix mishmash of random spacing in struct decls in glusterfs.h. Not technically a problem, just ugly to look at. 2) replace open-coded strings constants with existing #define constants. A disaster waiting to happen. 3) Use sys_access() instead of sys_stat() or sys_lstat() to test simple existence of file. Why copy dozens of bytes from kernel to user space that aren't going to be used by anything? There are probably more instances like these.
