4969639c7c executor: fix strict aliasing violations 
test_copyin does bad things. Fix that.

executor/test.h: In function ‘int test_copyin()’:
executor/common.h:299:16: error: dereferencing type-punned pointer will break strict-aliasing rules [-Werror=strict-aliasing]
   *(type*)(addr) = (type)(val);                                     \
                ^

9fe4bdc5f1 executor: overhaul 
Make as much code as possible shared between all OSes.
In particular main is now common across all OSes.
Make more code shared between executor and csource
(in particular, loop function and threaded execution logic).
Also make loop and threaded logic shared across all OSes.
Make more posix/unix code shared across OSes
(e.g. signal handling, pthread creation, etc).
Plus other changes along similar lines.
Also support test OS in executor (based on portable posix)
and add 4 arches that cover all execution modes
(fork server/no fork server, shmem/no shmem).

This change paves way for testing of executor code
and allows to preserve consistency across OSes and executor/csource.

570df9b277 sys/linux/socket_netlink_route: add specific policies for IFLA_LINKINFO 
Add interface specified policies for IFLA_LINKINFO. I only added the
interfaces we create in initial setup. Remain other types of interfaces
in the TODO list.

df5ae5f537 sys/akaros: don't call provision(-1) 
It causes kernel debug splat,

f25e577041 sys/linux: refine 9p descriptions 
RVERSION needs to use 0xffff tag, otherwise parsing fails.
Use only tags 1 and 2. They are densely allocated,
so most of the time it's 1. And it needs to be correct in
multiple replies for mount to succeed. So limit tag space.

c31f96a8c6 executor: rework fallback coverage 
We have fallback coverage implmentation for freebsd.
1. It's broken after some recent changes.
2. We need it for fuchsia, windows, akaros, linux too.
3. It's painful to work with C code.

Move fallback coverage to ipc package,
fix it and provide for all OSes.

dde158e0af sys/linux: refine xdp description 
Split sockaddr_xdp for bind.
Bind accepts another sock_xdp in addr.
Without the split getsockaddr "can" create sock_xdp's
because it returns generic sockaddr which contains
all addresses, including sockaddr_xdp, which in turn
contains sock_xdp.
