OpenGL ES 3.x contains a table of sized internal formats and their
required properties. In particular, each format is marked as
"Color Renderable" or "Texture Filterable".
This patch introduces two functions that can be used to query the
information from that table.

This function will be needed as part of validating the combination of format,
type and internal format of texture pixel operations, which happens in
glformats files. Specifically, we want to be able to obtain the base format
of a resolved effective internal format, to compare it with the original
internal format passed.
Also, since this function deals solely with GL formats, it fits better in
glformats where the rest of similar format functionality rests.
The function is moved as-is, without any modification.

In agreement with the ASTC spec, this makes calls to TexImage*D unsuccessful.
Implied by the spec, Generate[Texture]Mipmap and [Copy]Tex[Sub]Image*D calls
must be unsuccessful as well.
v2. actually force attempts to compress online to fail.
v3. indentation (Matt).
v4. update copytexture_error_check to account for CopyTexImage*D (Chad).

v2 after review by Jason Ekstrand:
- Move _mesa_format_from_format_and_type to glformats
- Return a mesa_format for GL_UNSIGNED_INT_8_8_8_8(_REV)
v3:
- Adapted to the new implementation of mesa_array_format as a plain uint32_t
bitfield.

This is necessary to handle conversions between array types where
the driver does not support the dst format requested by the client and
chooses a different format instead.
We will need this in _mesa_format_convert, so move it to format_utils.c,
prefix it with '_mesa_' and make it available to other files.
v2:
- Move _mesa_compute_component_mapping to glformats

As far as I can tell, the Intel mesa driver is the only driver in the world
still supporting this legacy extension. If someone wants to do bump
mapping, they can use shaders.

The comment for _mesa_is_type_integer is confusing because it says that it
returns whether the type is an “integer (non-normalized)” format. I don't
think it makes sense to say whether a type is normalized or not because it
depends on what format it is used with. For example, GL_RGBA+GL_UNSIGNED_BYTE
is normalized but GL_RGBA_INTEGER+GL_UNSIGNED_BYTE isn't. If the normalized
comment is just a mistake then it still doesn't make much sense because it is
missing the packed-pixel types such as GL_UNSIGNED_INT_5_6_5. If those were
added then it effectively just returns type != GL_FLOAT.
That function was only used in _mesa_is_enum_format_or_type_integer. This
function effectively checks whether the format is non-normalized or the type
is an integer. I can't think of any situation where that check would make
sense.
As far as I can tell neither of these functions have ever been used anywhere
so we should just remove them to avoid confusion.
These functions were added in 9ad8f431b2a47060bf05517246ab0fa8d249c800.

Previously, if the client program didn't specify a stride when setting
up a vertex attribute, we used _mesa_sizeof_type() to compute the size
of the type, and multiplied it by the number of components.
This didn't work for the 2_10_10_10 formats, since _mesa_sizeof_type()
returns -1 for those types, resulting in all kinds of havoc, since it
was causing the hardware to be programmed with a negative stride
value.
This patch adds a new function _mesa_bytes_per_vertex_attrib(), which
is similar to the existing function _mesa_bytes_per_pixel(), but which
computes the size of a vertex attribute based on the type and the
number of formats. For packed formats (currently only the 2_10_10_10
formats), it verifies that the number of components is correct and
returns the size of the packed format. For unpacked formats, it
returns the size of the type times the number of components.
In addition, this patch adds an assertion so that if we ever forget to
update _mesa_bytes_per_vertex_attrib() when adding a new vertex
format, we'll see the problem quickly rather than having to debug a
subtle conformance test failure.
Fixes GLES3 conformance tests
vertex_type_2_10_10_10_rev_{conversion,divisor,stride_pointer}.test.
