glx: Fix indirect multi-texture GL_DOUBLE coordinate arrays.

There is no draw arrays protocol support for multi-texture coordinate
arrays, so it is implemented by sending batches of immediate mode
commands from emit_element_none in indirect_vertex_array.c.  This sends
the target texture unit (which has been previously setup in the
array_state header field), followed by the texture coordinates.  But for
GL_DOUBLE coordinates the texture unit must be sent *after* the texture
coordinates. This is documented in the glx protocol description, and can
also be seen in the indirect.c immediate mode commands generated from
gl_API.xml. Sending the target texture unit in the wrong place can crash
the remote X server.

To fix this required some more extensive changes to
indirect_vertex_array.c and indirect_vertex_array_priv.h, in order to
remove the texture unit value out of the array_state "header" field, and
send it separately.
