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.

This removes a bunch of type assertions and makes code type safer.

Also add a test for this.

1. mmap all memory always, without explicit mmap calls in the program.
This makes lots of things much easier and removes lots of code.
Makes mmap not a special syscall and allows to fuzz without mmap enabled.
2. Change address assignment algorithm.
Current algorithm allocates unmapped addresses too frequently
and allows collisions between arguments of a single syscall.
The new algorithm analyzes actual allocations in the program
and places new arguments at unused locations.

Put the underflow entry at the end.
Entries must end on an unconditional, non-goto entry,
otherwise fallthrough from the last entry is invalid.
Add arp tables support.
Split unspec matches/targets to unspec and inet.
Reset ipv6 and arp tables in executor.
Fix number of counters in tables.
Plus a bunch of assorted fixes for matches/targets.

mknod$loop contains proc type as dev number.
Current sanitization code truncates 64-bit -1 to 32-bits
which later causes validation failure.
Don't do that, it's unnecessary for proc type.

KEYCTL_DH_COMPUTE used the old fixed list of algorithm names.
Use the new code for algorithm generation.
+ it needs only SHASH algs, but we passed in all alg names.
Pass only SHASH algs.

There is effectively infinite number of possible crypto
algorithm names due to templates. Plus there is tricky
relation between algorithms and algorithm type names.
This change adds custom mutator for sockaddr_alg struct
to improve variance in generated algorithms.

Nothing works, but builds.

Check that manager/fuzzer/executor are build on the same git revision,
use the same syscall descriptions and the same target arch.

Abstract "mmap" away as it can be called differently on another OS.

Currently we compile in only GOOS/GOARCH target.
Compile in all targets so that they can be selected at runtime.
