assigned-uniqueids: Miscellaneous cleanup and fixes.

Browse Source 
* Fix memory leak in ast_unreal_new_channels().  Made it generate the ;2
uniqueid on a stack variable instead of mallocing it.

* Made send error response to ARI and AMI requests instead of just logging
excessive uniqueid length and allowing truncation.  action_originate() and
ari_channels_handle_originate_with_id().

* Fixed minor truncating uniqueid hole when generating the ;2 uniqueid
string length.  Created public and internal lengths of uniqueid.  The
internal length can handle a max public uniqueid plus an appended ;2.

* free() and ast_free() are NULL tolerant so they don't need a NULL test
before calling.

* Made use better struct initialization format instead of the position
dependent initialization format.  Also anything not explicitly initialized
in the struct is initialized to zero by the compiler.

* Made ast_channel_internal_set_fake_ids() use the safer
ast_copy_string() instead of strncpy().
