32c61136ed Add one thread in periodic activities for the system interface 
This avoids that the system interface and the non-system interfaces
interfere each other.

c74fa6e908 Implement reusable lua engine 
The same Lua vm is now reused. After 5 minutes the vm is destroyed and
reloaded to prevent memory to grow too much. inotify is used to detected
changes in the filesystem (partially implemented, must implement a recursive
watch)

This optimizes periodic scripts calls by a 10x factor.

df0556cb87 Optimize flow alerts generation 
This provides a ~10x speedup by performing the JSON serialization work in C
(and thus avoiding Lua->C overhead). This also implements two in-memory alerts
queues (one for sqlite and one for the notifications) in order to reduce Redis load.
Alerts queue are now global instead of per-interface as there is only 1 dequeing thread.

0004e08191 Add experimental support for 5sec granularity for host timeseries 
To enable it (only on *InfluxDB* right now):

- uncomment HOST_NUM_TIMESERIES_POINTS in ntop_defines.h
- run `redis-cli set ntopng.prefs.30_sec_dump 1` and restart ntopng
