b88872ba0e sys/linux: add AF_NETLINK/NETLINK_ROUTE SCHED support 
Update #533

As TC(net sched) is a large group, I separate it from socket_netlink_route.txt.
Currently I only implement the framework with two qdisc/tclass/filters.
I will add the others later.

v2: Fix tcm_handle major and minor order. Add tcm_handle_offsets.

02e3401638 pkg/csource: skip tests under race detector 
csource tests consume too much memory under race detector (>1GB),
and periodically timeout on Travis. So we skip them.

31ea20ce83 sys: move generate files to separate packages 
Move generated files to gen subdir. This allows to:
1. Rebuild init.go without rebuilding generated code.
2. Excluding generated files from gometalinter checking.
This makes faster and consume less memory.

08a0ef9cb0 Makefile: fix deps 
syz-sysgen depends on prog which depends on pkg/ifuzz.
Currently we concurrently regenerate pkg/ifuzz and build
syz-sysgen, which can cause failures.
Make pkg/ifuzz dependent on syz-sysgen, so that it is
built before we regenerate ifuzz.

6a0382b543 prog: rework validation code 
The current code is total, unstructured mess.
Since we now have 1:1 type -> arg correspondence,
rework validation around args. This makes code
much cleaner and 30% shorter.

9ce14f4b01 prog: Fix page fault for syz-stress users. 
In resources.go, haveGettime is False when SyscallMap["clock_gettime"]
is nil.

In this code, there's a branch that's entered only if Gettime is False,
which appends SyscallMap["clock_gettime"] to resourceCtors.  That is, it
appends nil to resourceCtors, then iterates through resourceCtors and
tries to dereference the .Name of each time, in this case, nil.Name.

This was causing a page fault on Fuchsia.

I'm not certain how the "standard" flow is supposed to work, since it
seems like any code that enters the `if cantCreate == "" && !haveGettime`
should fail... but, removing that section causes test failures, so let's
just enforce that SyscallMap["clock_gettime"] is non-nil.

If there's a better way to solve this, I'm open to suggestions.
