Lukas Sismis 56c1552c3e hs: warn about the same cache directory 
This is especially relevant for multi-instance simultaneous setups
as we might risk read/write races.

Lukas Sismis 15c83be61a hs: prune stale MPM cache files 
Hyperscan MPM can cache the compiled contexts to files.
This however grows as rulesets change and leads to bloating
the system. This addition prunes the stale cache files based
on their modified file timestamp.

Part of this work incorporates new model for MPM cache stats
to split it out from the cache save function and aggregate
cache-related stats in one place (newly added pruning).

Lukas Sismis 7dc65c2f8a hyperscan: add caching mechanism for hyperscan contexts 
Cache Hyperscan serialized databases to disk to prevent compilation
of the same databases when Suricata is run again with the same
ruleset.
Hyperscan binary files are stored per rulegroup in the designated
folder, by default in the cached library folder.
Since caching is per signature group heads,
some chunk of the ruleset can change and it still can reuse part of
the unchanged signature groups.
