/*
 * 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.
