/*
* This subroutine will take the a_params of a sip_addr_s structure and spin through them.
* Each param will be used to create a channel variable.
* In the SIP RFC's, this data is called generic-param.
* Note that the tag-param is also included in the a_params list.
*
* From: "John Doe" <sip:5551212@1.2.3.4>;tag=ed23266b52cbb17eo2;ref=101;mbid=201
*
* For example, the header above will produce an a_params list with three entries
* tag=ed23266b52cbb17eo2
* ref=101
* mbid=201
*
* The a_params list is parsed and the lvalue is used to create the channel variable name while the
* rvalue is used to create the channel variable value.
*
* If no equal (=) sign is found during parsing, a channel variable name is created with the param and
* the value is set to NULL.
*
* Pointers are used for copying the sip_header_name for performance reasons. There are no calls to
* any string functions and no memory is allocated/dealocated. The only limiter is the size of the
* sip_header_name array.
