vcache decomposes primitives while vsplit splits primitives. Splitting
is generally easier to do and is faster. More importantly, vcache
depends on flatshade_first to decompose. The outputs may have incorrect
vertex order which is significant to GS.
vsplit is based on varray. It sets the split flags when a primitive is
splitted. It also has support for indexed primitives.
For indexed primitives, unlike vcache, vsplit splits the primitives
instead of decomposes them.
A primitive may be splitted in frontends. The splitted primitives
should convey certain flag bits so that the decomposer can correctly
decide the stipple or edge flags.
This commit adds flags to draw_prim_info and updates the decomposer to
honor the flags. Frontends and middle ends will be updated later.
This changes r300_destroy_context() so it can be called
on a partially-initialized context, and uses it when
r300_create_context() hits a fatal error.
This makes sure r300_create_context() doesn't leak memory
or neglect to call r300_update_num_contexts() when it fails.

This fixes a potential bug if (has_hyperz) is false
(it would still init the atom as if has_hyperz were true).

For 16 and 64 pixel levels, calculate a mask which is linear in x and
y (ie not in the swizzle layout).
When iterating over full and partial masks, figure out position by
manipulating the bit number set in the mask, rather than relying on
postion arrays.
Similarly, calculate the lower-level c values from dcdx, dcdy and the
position rather than relying on the step array.
This commit silences the printing off most of the debug information
when running debug builds. The big culprits are: the tgsi sanity checker
that gets run on all shaders on debug; all the options; and
finaly the cpu caps printer.
This is based on a patch by nobled <nobled@dreamwidth.org> and allows the TFP
extension to be enabled for DRISW also. This patch does not enable TFP for DRISW
though, because testing on xephyr segfaults here (for both classic and gallium):
Program received signal SIGSEGV, Segmentation fault.

The TFP code is generic except for the teximage call. We need to verify that
DRISW correclty implements whatever hook teximage finally calls.
