Originally it's from another branch.

The complication is that we need to work with addresses and
just file-descriptors passed from some parent process.
The former approach lead to logical duplication of some steps;
now we add a step converting addresses to file-descriptors.
Thanks to that we always do bind() without touching libuv,
so the problem with forking disappears :-)

That was against docs.  Fortunately, nil is falsy.

lua net.interfaces(): fix mac addresses

Only the first byte was being shown since 3ab77332.
I can't see at all why this part was changed;
the buffer is (and was) way overlong for this,
so writing one zero byte just after the end is OK.

We run meson with -std=gnu11, but apparently some compiler still
complained about it.  Unfortunately it wouldn't be easy to use
standard C11 in this case.

The layer functions are supposed to return the new state.
We've been lucky that errors are negative numbers and thus
they typically passed the (status & KR_STATE_FAIL) test.

... for layers and props.  This breaks C module API+ABI.

It seemed weird to repeatedly call a function that returns a pointer
to a structure in which we find the function we want to actually call.
We've never used changing these functions AFAIK, and the target
functions could easily be written to change their behavior instead
(i.e. move the indirection *inside* the function).

When breaking this, I also removed these two (_layers and _props)
from the dynamic symbols (to be) exported from the C modules.
They always pointed to memory belonging inside the module,
and they seem quite sensible to be set up by the _init symbol instead.

Fixes: #458

It gets handy for debugging, especially when looking at dufferent
callback "instances".

It would be pointless anyway as it cannot provide more information.

As far as I understand the debug.sethook('call') descrption we are not
going to have any locals except function parameters so we can simplify
the code.

Change handling of the inability to get address;
it happens occasionally and the traces were disruptive.

The problem is that C structures are not scanned by lua GC,
so we'd have to keep these alive in some other way; therefore
it's simpler to just use the mempool.

"Unfortunately", for FFI-bound C functions there it doesn't hold that
missing parameters would be converted to nil/NULL.
Still, this function seems unlikely to have been used outside the repo.

It caused crashes somewhere inside LuaJIT or the JIT-ed code.

The value is kind of arbitrary, as precaution. 64k value was causing
cqueues to close connections with GET requests with "Broken pipe"
and it seems to work with 1024 B.

This will allow modules like view etc. work in the same way with packets
received over HTTP.
