113a43ffb6 pkg/ipc: test only on simple prog 
Don't use random programs for testing.
Sometimes they lead to flakes like:
opendir(./1/file0) failed (errno 13)

b0d99d1ebb syz-ci: add config parameter that enables jobs

it's better to not start jobs polling loop at all.

7166783e9b pkg/report: fix crash during output parsing 
The test case causes rep.StartPos == secondReportPos,
which then makes extraction of description fail,
because report is empty.

11cf581658 executor: fix ifdef's for csource 
There is test failure on travis:
https://travis-ci.org/google/syzkaller/jobs/349948391
I can't reproduce it locally, and it only happened on 1.8, but not on 1.9?
But this seems to be what could have provoked such failure.

bbd5104f06 executor: fix includes 
We use errno, vaargs, printf in all of fail/error/exitf,
but we include the corresponding headers only when SYZ_USE_TMP_DIR.
Include them whenever fail/error/exitf are used.

42467f5b7b sys/linux: add syz_init_net_socket syscall 
The new pseudo syscall allows opening sockets that can only
be created in init net namespace (BLUETOOTH, NFC, LLC).
Use it to open these sockets.

Unfortunately this only works with sandbox none at the moment.
The problem is that setns of a network namespace requires CAP_SYS_ADMIN
in the target namespace, and we've lost all privs in the init namespace
during creation of a user namespace.

70a1ddb939 prog: harden program parsing against description changes more 
Handle most of type changes, e.g. const is changed to struct,
or struct to pointers. In all these cases we create default args.
They may not give the coverage anymore, but still better than
losing them right away.
