Really just spurious logging code.
If you're working on a device (as opposed to looking at bugreports)
you can get this information with for example 'bpftool':

Create new memevents subdirectory to contain bpf related files for libmemevents. Memevents-bpf are used to listen to kernel tracepoints (BPF_PROG_TYPE_TRACEPOINT), and skfilter bpf progrs to inject mock data for testing purposes (BPF_PROG_TYPE_SOCKET_FILTER).

Should make integration with BpfLoader written in rust easier.
While at it add simple wrappers around ALOG{V,D,I,W,E}(),
which may come in handy as bpfloader runs early enough that
logging must be to the kernel dmesg ringbuffer instead...

Move setting 'bpf.progs_loaded' property to 1 into mainline. This doesn't terribly matter, but it gives mainline bpf loading code a chance to run after platform and perform any required finalization. While at it also use distinctive error return values, as these are often the only thing that init reports about a bpfloader failure.

Should speed up boot time - especially if serial console is enabled. There's probably still enough information available to debug issues, as any errors (which basically shouldn't happen) are still all extensively logged. Either way, as this now only loads platform bpf .o files, anyone seeing boot time problems can simply flash a custom build with changes to the platform BpfLoader to enable any extra logging as needed. (Note that AFAICT normally ALOGV() is basically ignored) Test: TreeHugger Signed-off-by: Maciej Żenczykowski <maze@google.com> Change-Id: I5e404ae14c33ee319c07be42defdc270b15a54fe
