gallivm: Use nextafterf(0.5, 0.0) as rounding constant

The common truncf(x + 0.5) fails for the floating-point value just less
than 0.5 (nextafterf(0.5, 0.0)). nextafterf(0.5, 0.0) + 0.5, after
rounding is 1.0, thus truncf does not produce the desired value.

The solution is to add nextafterf(0.5, 0.0) instead of 0.5 before
truncating. This works for all values.

winsys/amdgpu: explicitly declare whether buffer_map is permanent or not

Introduce a new driver-private transfer flag RADEON_TRANSFER_TEMPORARY
that specifies whether the caller will use buffer_unmap or not. The
default behavior is set to permanent maps, because that's what drivers
do for Gallium buffer maps.

This should eliminate the need for hacks in libdrm. Assertions are added
to catch when the buffer_unmap calls don't match the (temporary)
buffer_map calls.

I did my best to update r600 for consistency (r300 needs no changes
because it never calls buffer_unmap), even though the radeon winsys
ignores the new flag.

As an added bonus, this should actually improve the performance of
the normal fast path, because we no longer call into libdrm at all
after the first map, and there's one less atomic in the winsys itself
(there are now no atomics left in the UNSYNCHRONIZED fast path).

mesa/main: fix incorrect depth-error

If glGetTexImage or glGetnTexImage is called with a level that doesn't
exist, we get an error message on this form:

Mesa: User error: GL_INVALID_VALUE in glGetTexImage(depth = 0)

This is clearly nonsensical, because these APIs don't even have a
depth-parameter. The reason is that get_texture_image_dims() return
all-zero dimensions for non-existent texture-images, and we go on to
validate these dimensions as if they were user-input, because
glGetTextureSubImage requires checking.

So let's split this logic in two, so glGetTextureSubImage can have
stricter input-validation. All arguments that are no longer validated
are generated internally by mesa, so there's no use in validating them.

mesa/main: remove bogus error for zero-sized images

The explanation quotes the spec on the following wording to justify the
error:

"An INVALID_VALUE error is generated if xoffset + width is greater than
 the texture’s width, yoffset + height is greater than the  texture’s
 height, or zoffset + depth is greater than the texture’s depth."

However, this shouldn't generate an error in the case where *all three*
of width, xoffset and the texture's width are zero. In this case, we end
up generating an unspecified error.

So let's remove this check, and instead make sure that we consider this
as an empty texture.

So let's not generate an error, there's non mandated in the spec in
xoffset/yoffset/zoffset = 0 case. We already avoid doing any work in
