Delyan Kratunov c2ec92f0ee libbpf: .text routines are subprograms in strict mode
Currently, libbpf considers a single routine in .text to be a program. This
is particularly confusing when it comes to library objects - a single routine
meant to be used as an extern will instead be considered a bpf_program.

This patch hides this compatibility behavior behind the pre-existing
SEC_NAME strict mode flag.

Delyan Kratunov 20442822c0 libbpf: Deprecate priv/set_priv storage
Arbitrary storage via bpf_*__set_priv/__priv is being deprecated
without a replacement ([1]). perf uses this capability, but most of
that is going away with the removal of prologue generation ([2]).
perf is already suppressing deprecation warnings, so the remaining
cleanup will happen separately.
