PATCH: beginning work for logging info by components

[herr_bpl]

Hi.

I needed to check why my pinger does not work, but when i set loglevel to debug, information is overhelming.. (like megabyte per 10secs.. I have lot of things to monitor )

So i devised a little patch to be able to select components, about which you wish to get logged information.

Following data should go to zabbix_server.conf

# Log components .. It is bitmap, so use precalculated sum for it..
#LOG_COMPONENT_ALL              0
#LOG_COMPONENT_ALERTER          1
#LOG_COMPONENT_ESCALATOR        1 << 1 = 2
#LOG_COMPONENT_HOUSEKEEPER      1 << 2 = 4
#LOG_COMPONENT_PINGER           1 << 3 = 8
#LOG_COMPONENT_POLLER           1 << 4 = 16
#LOG_COMPONENT_TIMER            1 << 5 = 32
#LOG_COMPONENT_TRAPPER          1 << 6 = 64
#LOG_COMPONENT_UNSPECIFIED      1 << 16 = 65536
# Defaults to LOG_COMPONENT_ALL
LogComponents=8

C files patch is attached for zabbix 1.1beta7

Hope this is useful for someone..
