Summary:                    [patch] logger.c may random crash asterisk on module
unload for some OS
Description: 

logmsg structure contain file and function pointer, which hold pointer to
file name and function name accordingly.
But memory, which these pointer refer, may be already freed and
inaccessible by logger thread - logger_thread(), if the module is already
unloaded at moment that logger thread call function to print this log
entry.

This mainly affected OS that use constructor/destructor.

Do a deep copy of file and function strings to avoid a potential crash
when
modules are unloaded.
