[Mesa-dev] [PATCH v2 7/8] i965: Clean up misleading defines for DWORD 2 of URB_WRITE header.

R02_PRIM_END and R02_PRIM_START don't actually refer to bits in DWORD
2 of R0 (as the name, and comments in the code, would seem to
indicate). Actually they refer to bits in DWORD 2 of the header for
URB_WRITE messages.
This patch renames the defines to reflect what they actually mean. It
also addes a define URB_WRITE_PRIM_TYPE_SHIFT, which previously was
just hardcoded in .c files.
