Feature: allow changing the identifier for syslog (+tests) 
Original "qb_log_ctl" interface had to be extended for passing read-only
strings (new parameter), resulting in new "qb_log_ctl2" function, which
is what qb_log_ctl calls into with the new parameter set to NULL.
This ensures backward compatibility.

A new QB_LOG_CONF_IDENT configuration directive for the mentioned
interface is added with a goal to set new internal identifier
that is, notably, used for syslog sink.  This allows for switching
the identification without a need to reinitialize logging subsystem,
akin to changing target logging facility.

Also a brand new concept of testing syslog sink in particular is
introduced (finally).  During initial trial&error stage, it used
LD_PRELOAD hack but it seems that libtool is sophisticated enough
that no such extra intervention is needed and the desired symbol
resolution Just Works (tm).  However, the technique is highly
non-portable (there is even a warning about that from libtool,
which is partially on purpose as the _syslog_override.so should
rather be explicit it is by no mean a regular library) and hence
the syslog tests have to be enabled with explicit

    ./configure --enable-syslog-tests

rather than possibly break on untested platforms (far too many).
The concept can be extended upon, but initially, just the new
feature is being tested.

Post-review: thanks Chrissie for a suggestion how to deal with
extract-arg-and-forget in a less intrusive way (no defines).

log: convert log target defined values into enum values 
Also use the new enum qb_log_target_slot type in for-loops together
with a proper substitute for the literal "0" initializer.

There could be more places that might be type-substituted for this enum
(and hence possibly catch more of an incorrect usage if the compiler
or checker has some notion of enum type narrowing), but leave it as
a possible enhancement for now.

dc1311f05e Feature: Implement "extended" logging using a marker character 
If a log message contains a magic character, everything after that marker
will be considered "extended" information. Log targets default to showing
this extended information but qb_log_ctl() may be used to indicate that
the extended information should be stripped instead.

The use case is a log message that has some information of value to administrators
and other information that is only of value for debugging. Two targets can be
configured such that the administrator log is not cluttered with debug information,
but a separate debug log is still available with complete information.

The magic character is the bell (\a). If someone wants to log an actual bell
character, they can do so in the extended information or via a %c format
(only the first bell is magic and only in the format string).

f5fcf2a30b LOG: add a way of getting the target state 
This is so we can do the following:

for (t = 0; t < QB_LOG_TARGET_MAX; t++) {
    if (qb_log_ctl(t, QB_LOG_CONF_STATE_GET, 0) == QB_LOG_STATE_ENABLED) {
        // bla bla
    }
}
