[Lognorm] [rsyslog] liblognorm

[Pavel Levshin]

Basically, you cannot have both versions available for compile, because 
they have conflicting header files. Pkg-config is a tool which works at 
compile time. It will detect just one installed version of the library, 
and you will build against this version. To have both versions 
available, you will need to place them at separate "prefixes", and 
select them manually at build time. I don't think it is really needed.

When you have built your software against some version of the library, 
this piece of software will require compatible version of dynamic 
loadable library to start. Older versions of software require 
liblognorm.so.0, but newer will search for liblognorm.so.1. Therefore, 
you can have both versions of dynamic loadable libraries installed at 
the same system.


Please note that I've just found a regression in my code: it is unable 
to strip quote marks from "quote-string" fields. I need to redo this part.
