New functions that can be used to search for a header with given type
This patch adds two new functions to the sip-router core. Function get_hdr can be used to find the first occurrence of header with a given type in a sip message if the particular header type does not have its own hook in the sip_msg data structure.
The second function next_sibling_hdr can be used to find the next occurence of header with the same type as the header in parameter in the sip message.
