4e92da06fa Dump counters in "dumpsys tethering bpf". 
This CL adds the counters collected by the tethering programs to
the output of "dumpsys tethering bpf". The counter names are
fetched by JNI code at startup and then read by the debugging
code on demand.

Example from my device:

  Forwarding errors:
    TCP_CONTROL_PACKET: 67
    NON_GLOBAL_SRC: 13
    NON_GLOBAL_DST: 17
    LOCAL_SRC_DST: 7

Test: manual (debug-only code)

547e168540 Move offload config hidl usage from native to java 
TetheringUtil JNI is too big that it statically linking hidl and its
dependency library. To remove these static libraries, calling hidl in java
directly instead of using JNI.

ee6ad37837 [Tether07] Migrate Tethering into module 
Now tethering would be run in dedicated service.
TetheringManager is the interface used to communicate with
TetheringService. The new call flow would be: ConnectivityManager
-> ConnectivityService -> TetheringManager -> TetheringService.
Note: the return value of #tether(), #untether() and #setUsbTethering()
APIs would always be no error. Client can use #getLastTetherError()
or #getTetheredIfaces or listen tether state change to check
status of corresponding interface.

6aa388904e [Tether06] Migrate tether offload controller into module 
The tether offload JNI library in this patch still have many dependencies
with internal libraries. Will have follow up changes to cut the
dependencies to let it be a unbundled library.
