e8dceddeec enable NETLINK_EXT_ACK extended error reporting 
(we don't yet do anything with it, but at least in strace we should
now see more detailed errors from the kernel)

20dcaf5f70 Fix wrong nla_type for matchall 
TCA_U32_ACT was missed when converting from the u32 filter to matchall.
Interestingly, cls_matchall does not seem to validate this type as the
kernel happily accepted this configuration (which absolutely should not
happen as TCA_U32_ACT is greater than __TCA_MATCHALL_MAX).

27846ff7a2 Add tests for libtcutils 
Add tests for isEthernet(). Before I can add tests for the other
functions, I need to move tcQdiscAddDevClsact into libtcutils.

e7f26e2a4d Move BpfUtils -- move kernelVersion code to its own header 
Move kernelVersion and isAtLeastKernelVersion to a local kernelversion.h,
since we cannot use bpf_headers' version of BpfUtils.

776c40cf65 Move BpfUtils -- add libtcutils 
This CL is copying the "generic" parts of BpfUtils to
frameworks/libs/net/common. "Generic" meaning the parts that will be
used by both TcUtils in frameworks/libs/net/common and netd.
