Make netsnmp headers compatible with C99.

Disable inlining by adding -DNETSNMP_NO_INLINE to CFLAGS. Since we
only use header files, this should not be a problem. A more valid fix
would be to turn NETSNMP_INLINE into "extern inline" instead of just
"inline".

Without this fix, we get a lot of warnings with gcc 4.3.
