res_pjsip_header_funcs: wrong pool used tdata headers
When adding headers to an outgoing request the headers were cloned using the dialog's pool when they should have been cloned using tdata's pool. Under certain circumstances it was possible for the dialog object, and its pool to be freed while tdata is still active and available. Thus the cloned header "disappeared", and when tdata tried to later access it a crash would occur. This patch makes it so all added headers are cloned appropriately using tdata's pool.
