Subject: [PATCH] Use ARRAY_SIZE macro
Replace array size calculations with ARRAY_SIZE macro.
Implemented with this Coccinelle semantic patch, adapted from
Linux kernel:
@@
type T;
T[] E;
@@
- (sizeof(E)/sizeof(*E))
+ ARRAY_SIZE(E)

- (sizeof(E)/sizeof(T))
+ ARRAY_SIZE(E)
Some files (*-dis.c, tests/*) had to be filtered out.
