Rene Sapiens 085467b8f5 staging: tidspbridge: set8 remove hungarian from structs
hungarian notation will be removed from the elements inside
structures, the next varibles will be renamed:

Original:                Replacement:
hbridge_context          bridge_context
hchnl_mgr                chnl_mgr
hcmm_mgr                 cmm_mgr
hdcd_mgr                 dcd_mgr
hdeh_mgr                 deh_mgr
hdev_obj                 dev_obj
hdrv_obj                 drv_obj
hmgr_obj                 mgr_obj
hmsg_mgr                 msg_mgr
hnode_mgr                node_mgr
psz_last_coff            last_coff
ul_resource              resource
ul_seg_id                seg_id
ul_size                  size
ul_sm_size               sm_size
ul_total_free_size       total_free_size
ul_total_in_use_cnt      total_in_use_cnt
ul_total_seg_size        total_seg_size
ul_trace_buffer_begin    trace_buffer_begin
ul_trace_buffer_current  trace_buffer_current
ul_trace_buffer_end      trace_buffer_end
ul_unit                  unit
ul_virt_size             virt_size
