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...

Prep work to make legacy BpfLoader usable as a library from rust. Note: fixups to make this actually build will be in the next commit.

The only non-test use of the library is the BpfLoader, so it makes sense for everything to use the same tag. Test: TreeHugger Signed-off-by: Maciej Żenczykowski <maze@google.com> Change-Id: Iddc0472a39db292fef31b2e195b3ab919d884f7d

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

For platform bpf .o files per-map/prog selinux context can simply be added by genfscon selinux policy modifications. (while per-map/prog pin dir really only exists to support the selinux context) Test: TreeHugger Both before and after this patch 'adb shell find /sys/fs/bpf | wc -l' returns 103 Signed-off-by: Maciej Żenczykowski <maze@google.com> Change-Id: Ic700db2870c16a04c9498e529519051a672a28c8

The only (real) user is the platform bpfloader binary. This is a library purely to facilitate testing. It's easier to develop / code-search if everything is in the same directory.
