    Modify chan_sip's packet generation api to automatically calculate the Content-Length.  This is done by storing packet content in a buffer until it is actually time to send the packet, at which time the size of the packet is calculated.  This change was made to ensure that the Content-Length is always correct.
    
    (closes issue #17326)
    Reported by: kenner
    Tested by: mnicholson, kenner
    
    Review: https://reviewboard.asterisk.org/r/693/
  ........
  
  
  This change also adds an ast_str_copy_string() function (similar to ast_copy_string), that copies one ast_str into another, properly handling embedded nulls.
