alessio 887502e37d Drop malformed notify messages early instead of decompressing them 
The DNS header shows if a message has multiple questions or invalid
NOTIFY sections. We can drop these messages early, right after parsing
the question. This matches RFC 9619 for multi-question messages and
Unbound's handling of NOTIFY.
To further add further robustness, we include an additional check for
unknown opcodes, and also drop those messages early.

Add early_sanity_check() function to check for these conditions:
- Messages with more than one question, as required by RFC 9619
- NOTIFY query messages containing answer sections (like Unbound)
- NOTIFY messages containing authority sections (like Unbound)
- Unknown opcodes.
