Removed:
    SSS_UNRESOLVED_DEBUG_LEVEL (completely replaced with SSSDBG_UNRESOLVED)

Added new macro:
    CONVERT_AND_SET_DEBUG_LEVEL(new_value)

Changes unresolved debug level value (SSSDBG_UNRESOLVED) from -1 to 0
so DEBUG macro could be reduced by one condition. Anyway, it has a minor
effect, every time you want to load debug_level from command line parameters,
you have to use following pattern:

    /* Set debug level to invalid value so we can deside if -d 0 was used. */
    debug_level = SSSDBG_INVALID;

    pc = poptGetContext(argv[0], argc, argv, long_options, 0);
    while((opt = poptGetNextOpt(pc)) != -1) { ... }

    CONVERT_AND_SET_DEBUG_LEVEL(debug_level);

Conversion of the old debug_level format to the new one.
(only where it was necessary)

Removed:
  SSS_DEFAULT_DEBUG_LEVEL (completely replaced with SSSDBG_DEFAULT)

RFC 2782 defines a way to sort replies to a SRV query. In short, the
algorithm sorts all replies by priority and then does a weight-based
selection for every priority level.

For details, please see the sections "Usage rules" for overview of the
algorithm and section "The 'Weight' field" for description on the weight
selection.

One of our resolv tests tries to resolve a nonexistent hostname. Do not
run this test unless we are explicitly told that a network connection
is available (-n). Also do not automatically resolving localhost.

Logs from confdb with missing '\n' in the DEBUG statements annoyed me so
I decided to fix them. I also made a quick grep through the code and
found other places so I fixed them too.
