+Subject: treewide: use uint* instead of u_int*
+
+Gcc complains about missing types. Some commits introduced u_int* instead
+of uint*. Use uint treewide.
+
+Fixes errors in the form of:
+In file included from xtables-legacy-multi.c:5:
+xshared.h:83:56: error: unknown type name 'u_int16_t'; did you mean 'uint16_t'?
+    83 | set_option(unsigned int *options, unsigned int option, u_int16_t *invflg,
+        |                                                        ^~~~~~~~~
+        |                                                        uint16_t
+make[6]: *** [Makefile:712: xtables_legacy_multi-xtables-legacy-multi.o] Error 1
+
+Avoid libipq API breakage by adjusting libipq.h include accordingly. For
+arpt_mangle.h kernel uAPI header, apply same change as in kernel commit
+e91ded8db5747 ("uapi: netfilter_arp: use __u8 instead of u_int8_t").
