Description:With the current implementation, the dnsmgr functions are only initialized after all loadable modules have already been loaded. As a consequence, the chan_iax2 loadable module (the only channeltype currently using dnsmgr DNS-caching) will not make use of dnsmgr functions unless we do a "iax2 reload".

The attached patch moves up the initialization of the dnsmgr functions to before the loadable modules are processed (preloaded), thus making its functionality available to e.g. all channeltypes that might make use of them. Again, as of today only IAX2 uses the dnsmgr_lookup function.

Feel free to reclassify from core_asterisk/General to more appropriate category.

****** ADDITIONAL INFORMATION ******

Original behavior (right after startup):

astlap*CLI> dnsmgr status
DNS Manager: enabled
Refresh Interval: 1200 seconds
Number of entries: 0

astlap*CLI> iax2 reload                                                        
 == Parsing '/etc/asterisk/iax.conf': Found

^@  == adding manager for 'yyyyyy.iax2.gafachi.com'

DNS Manager: enabled

astlap*CLI>  

With patch applied, right after startup:

astlap*CLI> dnsmgr status                                                                                                    
DNS Manager: enabled
Refresh Interval: 1200 seconds
Number of entries: 3

No need to "iax2 reload" anymore.
