Preliminary log matching support (the third)

[Christian Hopp]

Hi!

So that's my third and hopefully final version of my log matching support 
for file checks.  In addition to the older versions it addresses:

- a "real life" example in the docs
- bug fixes

Furthermore I did some stress testing for it.  I took the logcheck regex 
database (server) shipped with Debian Linux (>800 lines of regexs) and 
loaded it with the "IF MATCH path" and "IGNORE MATCH path" statement. 
Afterwards I gave monit pieces of 40-400 lines of my syslog output to 
chew.  Where 40 lines are hardly noticable (<1s), 400 lines give already 
some stress (~6s) (Pentium-M 1.7GHz).  But it worked. (:

Remaining issues:

- tuning of the event output... multi line output and logfiles do not go
  along nicely!
- external regex lib
