Donald points out most YNL makefiles are missing distclean
in .PHONY, even tho generated/Makefile does list it.

The make target to remove all generated files used to be called
"hardclean" because it deleted files which were tracked by git.
We no longer track generated user space files, so use the more
common "distclean" name.

Building samples generates the following warning:
In file included from page-pool.c:11:
generated/netdev-user.h:21:45: warning: ‘enum netdev_xdp_rx_metadata’ declared inside parameter list will not be visible outside of this definition or declaration
21 | const char *netdev_xdp_rx_metadata_str(enum netdev_xdp_rx_metadata value);

Our magic way of including uAPI headers assumes the sample
name matches the family name. We need to copy the flags over.

Regenerate the tools/ code after netdev spec changes.
Add sample to query page-pool info in a concise fashion:
$ ./page-pool
eth0[2] page pools: 10 (zombies: 0)
refs: 41984 bytes: 171966464 (refs: 0 bytes: 0)
recycling: 90.3% (alloc: 656:397681 recycle: 89652:270201)

Makefile.deps provides direct includes in CFLAGS_$(obj).
We just need to rewrite the rules to make use of the extra
flags, no need to hard-include all of tools/include/uapi.

The tool can be used to verify that everything works end to end.
Unrelated updates:
- include tools/include/uapi to pick the latest kernel uapi headers
- print "xdp-features" and "xdp-rx-metadata-features" so it's clear
which bitmask is being dumped

The inability to include the uAPI headers directly in tools/
is one of the bigger annoyances of compiling user space code.
Most projects trade the pain for smaller inconvenience of having
to copy the headers under tools/include.
In case of netlink headers I think that we can avoid both.
Netlink family headers are simple and should be self-contained.
We can try to twiddle the Makefile a little to force-include
just the family header, and use system headers for the rest.
This works fairly well. There are two warts - for some reason
if we specify -include $path/family.h as a compilation flag,
the #ifdef header guard does not seem to work. So we need
to throw the guard in on the command line as well. Seems like
GCC detects that the header is different and tries to include
both. Second problem is that make wants hash sign to be escaped
or not depending on the version. Sigh.

Add a sample application using the C library.
My main goal is to make writing selftests easier but until
I have some of those ready I think it's useful to show off
the functionality and let people poke and tinker.
Sample outputs - dump:
$ ./netdev
Select ifc ($ifindex; or 0 = dump; or -2 ntf check): 0
lo[1] 0:
enp1s0[2] 23: basic redirect rx-sg
Notifications (watching veth pair getting added and deleted):
$ ./netdev
Select ifc ($ifindex; or 0 = dump; or -2 ntf check): -2
[53] 0: (ntf: dev-add-ntf)
[54] 0: (ntf: dev-add-ntf)
[54] 23: basic redirect rx-sg (ntf: dev-change-ntf)
[53] 23: basic redirect rx-sg (ntf: dev-change-ntf)
[53] 23: basic redirect rx-sg (ntf: dev-del-ntf)
[54] 23: basic redirect rx-sg (ntf: dev-del-ntf)
