Alessandro Decina 4222b140ec aya: perf_map: fix bug when max_entries=0
When a perf map has max_entries=0, max_entries is dynamically set at
load time to the number of possible cpus as reported by
/sys/devices/system/cpu/possible.

This change fixes a bug where instead of setting max_entries to the
number of possible cpus, we were setting it to the cpu index of the last
possible cpu.

Update generated bindings with kernel headers from libbpf 4ccc1f0

Alessandro Decina c44393d59b xtask: codegen: use uapi kernel headers from libbpf
libbpf periodically syncs uapi headers from the kernel. Use those to
generate bindings so that we don't have to rely on distro packages
when we cut releases.

Alessandro Decina 30d2b25f11 aya: xdp: fix detaching on kernels older than 5.7
XDP_FLAGS_REPLACE was added in 5.7. Now for kernels >= 5.7 whenever we
detach an XDP program we pass along the program fd we expect to be
detaching. For older kernels, we just detach whatever is attached, which
is not great but it's the way the API worked pre XDP_FLAGS_REPLACE.
