When global constants' or class constants' availability is based on some
preprocessor condition, the generated arginfo header files wrap the
declarations in the preprocessor `#if` conditional blocks, one per declaration,
even if they are in the same conditional block based on comments in the stub
file. Instead of having multiple conditional blocks one after the other with
the same condition, combine them into a single conditional block.
UDP segmentation offload is an optimisation attempt by sending multiple
large enough datagrams over UDP which reduces syscalls as by default,
they have to be broke down in small UDP packets, it is better if the
hardware supports it, other handed down to the software implementation.

To possibly reduce the latency when polling packets by activating it
from the network interface for N microseconds.
The kernel by doing so, increase the CPU(s) activity bound to
the socket significantly.
Note that not only the kernel needs to have support enabled for it
(which the average distribution usually does) but the network
interface itself needs to support it too. If not, it is just a no-op.
- socket_addrinfo_lookup throws when hints is an indexed array.
- socket_get_option hardcoding size outputs to user when data
size known.

- `TCP_FUNCTION_ALIAS`: fetches the function pointer name alias (>= 14.0
only tough).
- `TCP_BBR_ALGORITHM`: set/get the underlying algorithm (0: netflix, 1:
google) when the BBR's TCP stack is used.
- `TCP_REUSPORT_LB_NUMA`: set/get a NUMA domain filter on the socket.

Allows to select an alternate TCP stack. For example with RACK,
a fast loss detection relying on timestamp per packet.
While it works system-wide, it can also apply in an individual socket level too.

Is to create socket for Internet Control Message Protocol context.
Due to their nature, they are meant to be used via
raw sockets rather than TCP/UDP.
