The evolution of TX_FORMAT bits is as follows:
* When a texture is created, set bits independent of pipe_format.
* When a sampler view is created, add format-specific bits.
* When sampler states and views are getting merged, add min/max LOD.

This is most likely a bug in the mesa state tracker, but do the quick hack
for now to avoid the divide by 0.

Signed-off-by: Dave Airlie <airlied@redhat.com>

A native display has no interest in depth/stencil format.  Remove it
from the interface and let the common code derive the supported
depth/stencil formats from the pipe screen.

The implementation requires not only a depth buffer, but also a stencil
buffer.

Replace __GLcontextModes by a subset of its attributes that makes sense
to EGL.  This also gets rid of GL headers from the common code.

    util: fix up several uses of pipe_map_buffer_range

    This function used to return a pointer to where the start of the
    actual buffer would have been, even though only the requested range is
    being mapped.

    In the resources change, the function was modified to use a transfer
    internally, and started returning the pointer to the beginning of the
    transfer, ie the mapped range.

    Some users of the function were changed to reflect this new behaviour,
    some were not.  Since then the function has reverted to its original
    behaviour, matching master.

    This change restores some of the users of the map_buffer_range helper
    to expect the old/original behaviour.

    nvfx: fix for gallium-resources

    It seems to work with basic applications but almost surely needs more work.

    In particular, it probably shouldn't use PIPE_BUFFER_USAGE_* flags
    and should use PIPE_TRANSFER_* in several places.

    Also, we probably don't want the vtable indirect calls and that ought
    to be replaced with something better instead.

    nouveau: convert nvfx and nv50 to pipe_resources

    Compile tested only.

    This was a deeper change than I was hoping for, due to the
    layering of the pipe_texture implementation in each driver on
    top of a shared pipe_buffer implementation in the shared code.

    Have modified the shared code to act as a set of convenience
    routines operating on nouveau_bo objects.

    Each driver now uses the u_resource_vtbl technique to split the
    implementation of pipe_resources between the existing miptree code
    for textures and a new, minimal buffer implementation in each
    driver.

    Eventually these should be combined, not least because APIs are now
    allowing things like binding buffer resources as textures and render
    targets.

    r300: convert to pipe_resources

    Do a very shallow conversion - basically keeping the existing
    buffer and texture code intact and using a vtbl struct
    inside our resource struct to select between the two implementations.

    The buffer and texture treatments could be further merged without
    much effort, but try to keep the existing code working at this point.

    wip

Needed by the CS checker.

We've supported indirect rendering pbuffers for a while, but not direct
rendering pbuffers.  The way we do this is by creating a hidden pixmap
and wrap that in a GLX pbuffer.  This only works when we have DRI2 on
the server, but if the server doesn't have DRI2, it won't expose configs
with pbuffer bits enabled.

When matching attributes using the 'mask' matching criteria, the spec
says that

  "Only GLXFBConfigs for which the set bits of attribute include all
   the bits that are set in the requested value are
   considered. (Additional bits might be set in the attribute)."

The current test returns true if the two bit masks have bits in
common, specifically it matches even if the requested value has bits
set that are not set in the fbconfig attribute.  For example, an
application asking for

  GLX_DRAWABLE_TYPE, GLX_PIXMAP_BIT | GLX_PBUFFER_BIT,

as glxpbdemo does, will match fbconfigs that don't support pbuffer
rendering, as long as they support pixmap rendering.

When the vertex shader emitted both a texcoord and color we were grabbing

the vertex shader code.
