Some of the larger change blocks are the result of extracting the body of a loop to fix the usage of ast_strdupa() inside the loop.

    Red blob.

    Got red blob.

    Reviewboard is confused here.  I did not touch this line so the red blob is not mine.  I'll not fix.

    This change is not really parking related, but it was calling ast_channel_masquerade() with both channels locked.  This is something that really should not be done since ast_channel_masquerade() is going to do deadlock avoidance itself.
