Load a configuration from a stream.
Load a default configuration file.
Each section of the text should begin with a category. A logger named "A.B.C" will be controlled by a section labelled A.B.C The categories labels have a hierarchical structure, so if A.B.C doesn't exist, the code will look for a section labelled A.B, or A. If none of these exist it will use the "root" category. Each category has a level. If a log message has the same or higher priority than the given level, the message will be output. Finally the category destination must be specified as a "file_output" and the filename or "stream_output" and the stream name. The known stream names are "vcl_cout" and "vcl_cerr", and additional names can be provided through stream_names. The
root: { level: INFO stream_output: test }
obj3: { level: INFO stream_output: vcl_cout }\n
obj3.obj6: { level: INFO file_output: results.txt }\n
obj3.obj7.images: { level: INFO stream_output: vcl_cout dump_prefix: ./logging_dir/ }\n

Load a default configuration file.
This function will look for a configuration file called "mbl_log.properties" in the current directory, or if no there, in the user's home directory. Unix users can call it ".mbl_log.properties" in their home directory. See load_log_config() for description of config file format, and stream_names.

Force all loggers to update themselves in light of changes to the root and configuration.
This is already called automatically by load_log_config_file().
