pkg-config uses uppercase for its _CFLAGS and _LIBS variable names.
So we follow suit and convert all _cflags and _libs variables to
uppercase for more consistency.

thanks to David Lang for his excellent performance analysis

the markmessageinterval was not correctly propagated to all places
where it was needed. This resulted in rsyslog using the default
(20 minutes) in some code pathes, what looked to the user like mark
messages were never written.

Also added redirector to web description of error codes

- added the ability to specify an error log function for the
  runtime
- removed dependency of core runtime on dirty.h

Note that it is "better" modularity, not perfect. There is still
work to do, but I think we can for the time being proceed with
other things.

reduced dependencies, moved non-runtime files to its own directory except
for some whom's status is unclear
