Likewise fix default configuration to use SOCK_DGRAM and not SOCK_STREAM
as we currently do.

Add sha256 digest.

Rather than have the users replace syslog-ng.conf (which lately is
changing fairly frequently) and have them miss an important fix or
improvement, instead have them localize /etc/custom-logs.conf and
ship that as an empty file.

Install the plugins as various functionality is no longer in the
utility itself but is packaged as a .so plugin instead. Disable
plugins with too many dependencies (or too exotic).

Bump the version number on the config file to agree with the package's
version number.

Clean up any .la files from libtool.

Start much earlier so that logging doesn't miss startup messages from
other services.
