scl/scl.conf: Use a wildcard to include SCL snippets

To be able to install SCL snippets to be included by default, without
modifying scl.conf itself, use a wildcard-include. This allows
distributions to ship some of the SCLs in different packages, without
breaking the default config, or having to enable them in other ways.

afsql: trying to do a better transaction handling

Two problems with transactions:
 * mixing DDL and DML statements in a single transaction
   (create/update table)
 * simple select can abort a transaction
   (checking if a table exists or not)

syslog-ng checks whether a table exists or not by 'select * from table'
(and get structure of the table as a side-effect...)

There are some DB-providers which abort current transaction when try to
select from a non-existing table (eg.:mssql).

libdbi provides a better, db-provider specific way to checking table existance
(this is a meta-query which always succeed).
Unfortunately, this function is buggy in pgsql driver, so we had to do
something else).

syslog-ng asks db only when the name of the table to be checked is not seen
before (this is based on a runtime information: every table is validated and
name of all validated tables are stored in a hashtable).

When the table not found in the list of validated tables:
 - active transaction is commited (if exists)
 - new transaction is started for checking if the table exists or not
    - if the table exists, its structure is updated according to the
      structure given in the config file
    - otherwise a new table is created

timeutils: fix bad pointer cast that leads to timestamp overwriting

In `log_msg_parse_date()` the variable `now` is of type `GTimeVal`.
Its member `tv_sec` is of type `long`, and its address was cast to a `time_t`
pointer.
This led bad argument passing to the `cached_localtime()` function.

Fixes: #304

systemd: remove syslog.socket references from service file

Syslog-ng reads the messages directly from journal on systems with systemd, so
we don't need these settings anymore.
