This patch set removes all the deprecated APIs in preparation for 1.0 release.
It also makes libbpf_set_strict_mode() a no-op (but keeps it to let per-1.0
applications buildable and dynamically linkable against libbpf 1.0 if they
were already libbpf-1.0 ready) and starts enforcing all the
behaviors that were previously opt-in through libbpf_set_strict_mode().
xsk.{c,h} parts that are now properly provided by libxdp ([0]) are still used
by xdpxceiver.c in selftest/bpf, so I've moved xsk.{c,h} with barely any
changes to under selftests/bpf.
Other than that, apart from removing all the LIBBPF_DEPRECATED-marked APIs,
there is a bunch of internal clean ups allowed by that. I've also "restored"
libbpf.map inheritance chain while removing all the deprecated APIs. I think
that's the right way to do this, as applications using libbpf as shared
library but not relying on any deprecated APIs (i.e., "good citizens" that
prepared for libbpf 1.0 release ahead of time to minimize disruption) should
be able to link both against 0.x and 1.x versions. Either way, it doesn't seem
to break anything and preserve a history on when each "surviving" API was
added.
NOTE. This shouldn't be yet landed until Jiri's changes ([1]) removing last
deprecated API usage in perf lands. But I thought to post it now to get the
ball rolling.
