Following DPDK's recommendation to size mempool to 2^n - 1,
the current implementation was flawed for certain combos,
e.g. mp_size 1023 and 1 queue, which resulted to 1022.
Hash Hyperscan installation info (version, CPU features, mode)
into the cache filename. A Hyperscan upgrade or platform change
would now produce a different filename, so stale caches from an
older installation are never opened.
Ticket: 8325
After deserializing a cached Hyperscan database, verify that its
version, CPU features, and mode match the current Hyperscan
installation by comparing hs_database_info output against a
reference database. Reject loading incompatible caches.
Ticket: 8325
HSSaveCache wrote serialized Hyperscan databases using text mode ("w")
while HSReadStream already read them with binary mode ("rb").
Matched file reading modes to the binary format and simplified
write-size check.
Ticket: 8325
HSLoadCache opened the cache file but never used the resulting handle
for reading. The actual read was done by HSReadStream which opened
the same file independently.
Removed the unused fopen/fclose pair and flattened the control flow.

Reduce logging level of a minor informational message.
Split tracking of pruning by age and by version and log those
separately, where the logging only appears if something has been
removed.

The end goal is to remove all dependencies on suricata and just
use suricata_sys or suricata_ffi
For now, make usage of what is already available

Allows for instance to process/log ARP packets over VXLAN.
That means we need to decode the ethernet layer above vxlan
instead of skipping it as part of the vxlan, even if the vxlan
decoder still checks the ethernet layer to avoid FPs.
Instead of directly accessing the field
Will allow PacketTunnelType to hold the precise tunnel type like
DECODE_TUNNEL_ERSPANII with a modification of PacketIsTunnelChild
Refactor pcap file deletion to use a single delete-when-done option
with three values instead of separate boolean options:
- false (default): No deletion
- true: Always delete files
- "non-alerts": Delete only files with no alerts
Also account for alerts produced by pseudo packets (flow timeout / shutdown flush):
- Introduce small capture hooks and invoke on pseudo-packet creation so the
capture layer can retain references and observe alerts emitted after the last
live packet
- Call the hook from both TmThreadDisableReceiveThreads and TmThreadDrainPacketThreads
Key changes:
- Replace should_delete/delete_non_alerts_only bools with enum
- Move alert counter from global to per-file PcapFileFileVars
- Relocate alert counting from PacketAlertFinalize to pcap module
- Ensure thread safety for both single and continuous pcap modes
- Add unit tests for configuration parsing and pseudo-packet alert path
The --pcap-file-delete command line option overrides YAML config
and forces "always delete" mode for backward compatibility.
Documentation updated to reflect the new three-value configuration.
Fixes OISF#7786
