#1811: Varnish crashes when a PRIV_TASK/PRIV_TOP function is invoked from vcl_init

varnishd[17072]: Child (17074) Panic message:#012Assert error in
VRT_priv_task(), cache/cache_vrt_priv.c line 119:#12 Condition((ctx->bo)
!= NULL) not true.
``

what happens is that VRT_priv_dynamic stores its list of privs in one of
ctx->req->sp->privs or ctx->bo->privs, neither of which are available from
vcl_init.

I'm not sure if the solution is to teach the VCL compiler to disallow the
invocation of PRIV_{TASK,TOP} in vcl_init, or if we can find a better way
to handle this?
