This commit adds quic.h to include/uapi/linux, providing the necessary
definitions for the QUIC socket API. Exporting this header allows both
user space applications and kernel subsystems to access QUIC-related
control messages, socket options, and event/notification interfaces.

Since kernel_get/setsockopt() is no longer available to kernel consumers,
a corresponding internal header, include/linux/quic.h, is added.

Re-adding kernel_get/setsockopt() variants after removal, but just for a
single protocol is a bit ackward. The current series does not have any
user.

Do such helpers save a lot of duplicate code? Otherwise I would instead
expose quic_do_{get,set}sockopt().

Not much, just when using quic_do_{get,set}sockopt(), KERNEL_SOCKPTR()
will be used around the optval and optlen.

It should be fine to change to expose quic_do_{get,set}sockopt().

Thanks.
