The package level var native (holding the native endianness) is
initialized at package load time. Thus there is no need to re-initalize
it in functions using it, e.g. (*Handle).filterModify, parseU32Data,
parseFwData, parseBpfData and parseMatchAllData.
This fixes a data race between these functions and any read access of
var native, e.g. in LinkDeserialize as reported in issue #633.
Also don't re-declare local variables shadowing the global package-level
var.
Fixes#633

- Prio and Quantum should be set equal to the input params
- Fix buffer and cbuffer due to incorrect hz
- Fix Xmittime which is also not equal the behavior of c library.
C library converts time to uint32 to drop precision before multiply
tick_in_usec. ref https://git.kernel.org/pub/scm/network/iproute2/iproute2.git/tree/tc/tc_core.c#n62
There was something off with the math for the ServiceCurves. The set value was 8
times too large and the returned one was 8 times too small.
This is now fixed in `class.go` and `class_linux.go` so the user can just set the rate in bit and
it will match the tc show output.
Testing and functionality for the use of HFSC has been implemented.
The use of service curves is implenented closely as to how they behave
with the TC implementation.
Automated checks and testing were succesful.
This patch adds ClassStatistics, a struct that represents the stats
of a class based on genric networking stats for netlink, to ClassAttrs.
The parsers for rtattrs in type of TCA_STATS and TCA_STATS2 are
introduced as well and the stats are appropriately parsed as a part
of ClassAttrs struct.
The practical tests for stats are not contained in this patch yet since
it requires the actual packet sending/receiving in the random timing,
which makes the tests complicated and flaky. Once we figure it out how
to test them in the proper way, they shall be added.

- Package methods only need an empty handle.
Not a regular Handle with a couple of
sockets creation/delete.

- Ties to a netlink socket. All client requests
will re-use same socket. Socket released at
handle deletion.
- Also network namespace can be specified during
handle creation. Socket will be opened on the
specified network namespace.
