int r100_cs_packet_parse_vline

(

r100_cs_packet_next_vline() - parse userspace VLINE packet : parser structure holding parsing context.

Userspace sends a special sequence for VLINE waits. PACKET0 - VLINE_START_END + value PACKET0 - WAIT_UNTIL +_value RELOC (P3) - crtc_id in reloc.

This function parses this and relocates the VLINE START END and WAIT UNTIL packets to the correct crtc. It also detects a switched off crtc and nulls out the wait in that case.
