88a3bf8aab security: validate packet length in AVB get_avb_info handler
Memory Safety: High

The handle_get_avb_info_common() function copied network packet data
into a stack buffer using memcpy(buf, m, len) without validating that
len fits within the 2048-byte buffer. A crafted AVB packet with a
large length could overflow the stack buffer. Added bounds validation
matching the pattern already used in handle_read_descriptor_common().

46eefd16ee security: fix out-of-bounds read in AVB AECP AEM command handler
Memory Safety: High

The cmd_names[] array was indexed with a network-provided command type
value before the bounds check, allowing an out-of-bounds read when
processing crafted AVB network packets. Moved the bounds validation
before the array access to prevent reading past the end of the array.

c551acf4d1 milan-avb: lock: make it lockable:
1. The period calls were added to handle timeouts.
2. Handle the case where lock must be unlocked after 60s if the
   controller owning the locked does not release it.

4e62826e01 module-avb: fix legacy AECP handlers reading payload at wrong offset
handle_acquire_entity_avb_legacy() and handle_lock_entity_avb_legacy()
incorrectly treated the full ethernet frame pointer as the AEM packet
pointer, causing p->payload to read descriptor_type and descriptor_id
from the wrong offset. Fix by properly skipping the ethernet header,
matching the pattern used by all other AEM command handlers.

c2ada3175e module-avb: aecp-aem: SET/GET STREAM_FORMAT answer implemented.
In the current state the GET/SET stream format can handle the commands
response however, yet, it does not take care of checking that:

 * A bound input stream cannot have it set, should reply accordingly
 * A STREAMING_STREAM output stream cannot have it set, should reply
   accordingly.

8e870c809c module-avb: aecp-aem: introducing seperation between milan v1.2 and legacy milan.
This introduces the following changes:

 * Using the time at which the command was received
 * Preparation for the unsollicited notifications
 * New folder holding all the AECP_AEM commands/responses and utils
 * Improving the code-reusability by using common handlers
