radeonsi: fix texture gather on stencil textures

At least on VI, texture gather doesn't work with a 24_8 data format, so
use 8_8_8_8 and a modified swizzle instead.

A bit of background: When creating a GL_STENCIL_INDEX8 texture, we select
the X24S8 pipe format because we don't support stencil-only render targets
properly. With mip-mapping this can lead to a setup where the tiling is
incompatible with stencil texturing, and a flushed stencil texture is
used. For the flushed stencil, a literal X24S8 is used because there were
issues with an 8bpp DB->CB copy.

Longer term, it would be good if we could get away from these workarounds,
i.e. properly support an S8 format for stencil-only rendering and flushed
stencil. Since stencil texturing is somewhat rare, it's not a high
priority.

mesa/main: Fix FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE for NONE attachment type

When the attachment type is NONE (att->Type),
FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE should be NONE always.

Note that technically, the current behaviour follows the spec. From
OpenGL 4.5 spec, Section 9.2.3 "Framebuffer Object Queries":

   "If the value of FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE is NONE, then
    either no framebuffer is bound to target; or the default
    framebuffer is bound, attachment is DEPTH or STENCIL, and the
    number of depth or stencil bits, respectively, is zero."

Reading literally this paragraph, for the default framebuffer, NONE
should be only returned if attachment is DEPTH and STENCIL without
being allocated.

But it doesn't makes too much sense to return DEFAULT_FRAMEBUFFER if
the attachment type is NONE. For example, this can happens if the
attachment is FRONT_RIGHT run on monoscopic mode, as that attachment
is only available on stereo mode.

With the current behaviour, defensive querying of the object type
would not work properly. So you could query the object type checking
for NONE, get DEFAULT_FRAMEBUFFER, and then get and INVALID_OPERATION
when requesting other pnames (like RED_SIZE), as the real attachment
type is NONE.

This fixes:
GL45-CTS.direct_state_access.framebuffers_get_attachment_parameters

i965/blorp: Make post draw flush more explicit

Blits do not need any special treatment as the target buffer
object is added to render cache just as one does for normal draw.
Color clears and resolves in turn require explicit "end of pipe

assumption is that render cache flush with command stream stall

i965: Make depth clear flushing more explicit

Current blorp logic issues unconditional "flush everything"
(see brw_emit_mi_flush()) after each render. For example, all
blits issue this unconditionally which shouldn't be needed if
they set render cache properly so that subsequent renders do
necessary flushing before drawing.

In case of piglit:

ext_framebuffer_multisample-accuracy all_samples depth_draw small

intel_hiz_exec() is always preceded by blorb blit and the
unconditional flush looks to hide the lack of stall and flushes
in depth clears. By removing the brw_emit_mi_flush() I get gpu

Signed-off-by: Emil Velikov <emil.velikov@collabora.com>

util: import sha1 implementation from OpenBSD

At the moment we support 5+ different implementations each with varying
amount of bugs - from thread safely problems [1], to outright broken
implementation(s) [2]

In order to accommodate these we have 150+ lines of configure script and
extra two configure toggles. Whist an actual implementation being
~200loc and our current compat wrapping ~250.

Let's not forget that different people use different code paths, thus
effectively makes it harder to test and debug since the default
implementation is automatically detected.

To minimise all these lovely experiences, import the "100% Public
Domain" OpenBSD sha1 implementation. Clearly document any changes needed
to get building correctly, since many/most of those can be upstreamed
making future syncs easier.

As an added bonus this will avoid all the 'fun' experiences trying to
integrate it with the Android and SCons builds.
