/*! Used for sending a log message */
/*!
\brief This is the standard logger function. Probably the only way you will invoke it would be something like this:
ast_log(LOG_WHATEVER, "Problem with the %s Captain. We should get some more. Will %d be enough?", "flux capacitor", 10);
where WHATEVER is one of ERROR, DEBUG, EVENT, NOTICE, or WARNING depending
on which log you wish to output to. These are implemented as macros, that
will provide the function with the needed arguments.
\param level Type of log event
\param file Will be provided by the LOG_* macro
\param line Will be provided by the LOG_* macro
\param function Will be provided by the LOG_* macro
\param fmt This is what is important. The format is the same as your favorite breed of printf. You know how that works, right? :-)

\brief This works like ast_log, but prints verbose messages to the console depending on verbosity level set.

This will print the message to the console if the verbose level is set to a level >= 3
Note the abscence of a comma after the VERBOSE_PREFIX_3. This is important.
VERBOSE_PREFIX_1 through VERBOSE_PREFIX_3 are defined.
