Travis is still broken with:
E: Unable to locate package gcc-aarch64-linux-gnu

Let's at least see what's OS is there and what gcc packages present.
Travis CI started failing with:
E: Unable to locate package gcc-aarch64-linux-gnu
E: Unable to locate package gcc-arm-linux-gnueabihf
E: Unable to locate package gcc-powerpc64le-linux-gnu
make: *** [install_prerequisites] Error 100

Let's try to ignore these packages.
Print each constant on separate line.
When compiler prints error messages it prints whole line
containing an error. So currently it prints all constants (thousands).
With this change it prints just the problematic constant.
For now other arches are regenerated on upstream tree.
It does not contain a bunch of consts, so we define them to 1 for now.
arm64 consts are left intact.
video4linux.txt is added to "android" files in syz-extract,
so that future make extract runs don't overwrite arm64 consts.
Also fix VIDIOC_G_FBUF argument direction, currently tests crash with:
panic: call ioctl$VIDIOC_G_FBUF: pointer arg 'buffer' has output direction [recovered]
panic: call ioctl$VIDIOC_G_FBUF: pointer arg 'buffer' has output direction
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.

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.
Update #538
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.
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.
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.
