docutils installs "rst2man.py" per default, so we need to check for both
variants:
* "rst2man" when using python-docutils from Ubuntu
* "rst2man.py" when using docutils from upstream
Newer versions of liblogging were restructured and now also contain
other components besides rfc3195. As a result the original liblogging
library was split and the rfc3195 component was renamed to
liblogging-rfc3195 along with its pkg-config file.
Update the configure check accordingly.
Since we require liblogging >= 1.0.1 anyway, don't add a fallback check
for the old pkg-config name.
Fixes#30
Newer automake versions complain if we use source files in subdirectories:
autoreconf: running: automake --add-missing --copy --force-missing
plugins/omelasticsearch/Makefile.am:4: warning: source file 'cJSON/cjson.c' is in a subdirectory,
plugins/omelasticsearch/Makefile.am:4: but option 'subdir-objects' is disabled
automake: warning: possible forward-incompatibility.
automake: At least a source file is in a subdirectory, but the 'subdir-objects'
automake: automake option hasn't been enabled. For now, the corresponding output
automake: object file(s) will be placed in the top-level directory. However,
automake: this behaviour will change in future Automake versions: they will
automake: unconditionally cause object files to be placed in the same subdirectory
automake: of the corresponding sources.
automake: You are advised to start using 'subdir-objects' option throughout your
automake: project, to avoid future incompatibilities.

Explicitly set the 'subdir-objects' option to avoid any future issues.
