[ANN] Lunatik v3.7 released

[Lourival Vieira Neto]

We are pleased to announce the release of Lunatik v3.7, introducing
new features and improvements for in-kernel Lua scripting.

What is Lunatik?

Lunatik is an in-kernel Lua runtime that allows Lua scripts to be
executed in kernel space without recompilation. It provides a
lightweight and modular approach to extending kernel functionality
with scripting.

What's New in v3.7?

New bindings for Linux crypto APIs:
- aead, skcipher, shash, rng, comp, and hkdf
- These make it possible to implement cryptographic operations,
including TLS encryption and decryption, directly in Lua scripts
inside the kernel.

Virtual memory support:
- Lunatik now uses kvmalloc() to allocate memory from the kernel's
virtual address space, enabling the use of non-contiguous memory. This
allows Lua scripts to handle larger data structures.

SKB marks in luanetfilter:
- Lua scripts can now read and set skb->mark, which is useful for
traffic classification and control in packet filtering applications.

VT notifier chain in luanotifier:
- Lua scripts can now subscribe to and handle virtual terminal events
from the kernel.

Upgraded Lua version:
- Lunatik now embeds Lua 5.4.8, the latest stable release.

Improved documentation:
- The project now has LDoc-based documentation available at:
https://luainkernel.github.io/lunatik/
