Key and value formats for time in state related BPF maps currently
have to be kept in sync between the BPF prog and
libtimeinstate. Add a new bpf_timeinstate.h header file in a directory
that already gets added to the include path for BPF progs, and add
this file to a cc_library_headers module so it can be used from
libtimeinstate as well.
Test: build libtimeinstate and time_in_state.o

For the eBPF programs that only related to networking, move them back
to netd so for the future changes in networking eBPF area, there is not
need to make changes in both netd project and bpf project.

The BPF helper is moved into system/bpf/include/ and is available
to all BPF programs in the include search path. Make use of it.
Only minor refactor, no functional change.

Add support for cgroup socket filter program loading in bpfloader,
and create a uid permission map to store the uids that have INTERNET
permission.

Use two maps to record the details of network stats and swap and clean
up after system server pulls the stats. The kernel program checks the
bpf map currently enabled before updating the stats and updates on the
corresponding map. Remove the TAG_STATS_MAP since we don't need to worry
about uid stats overflow problem. All the stats can be stored in the
same map until system server scrapes the stats and clean it up.

Change the netd bpf program to the new format. Adding map definition and
necessary helper functions to the kernel program code. Move the netd bpf
