This adds a table of driver descriptions to cogl-renderer.c in order of
preference and when choosing what driver to use we now iterate the table
instead of repeating boilerplate checks. For handling the "default driver"
that can be specified when building cogl and handling driver overrides
there is a foreach_driver_description() that will make sure to iterate
the default driver first or if an override has been set then nothing but
the override will be considered.
This patch introduces some driver flags that let us broadly categorize
what kind of GL driver we are currently running on. Since there are
numerous OpenGL apis with different broad feature sets and new apis
may be introduced in the future by Khronos then we should tend to
avoid using the driver id to do runtime feature checking. These flags
provide a more stable quantity for broad feature checks.

The data->fill_primitive member is meant to be generated on demand in

crash if nothing else caused the primitive to be generated. This was

Full GL treats the position attribute specially and requires that it
must be bound to generic attribute location 0 unlike GLES 2.0 or
GL 3.2 core. We now make sure to unconditionally bind the
cogl_position_in attribute to location 0 before linking any glsl program
in cogl.
For reference the relevant part of the GL 3.0 spec that covers these
semantics is Section 2.7 "Vertex Specification" pg 27
After this change there was one remaining problem in
test-custom-attributes where the test_short_verts() test was using its
own "pos" attribute instead of cogl_position_in and so cogl wasn't able
to ensure it would be bound to location 0.
This updates the test to use cogl_position_in but to work around the
fact that glVertexPointer doesn't support UNSIGNED_SHORT components we
force the test to use the glsl backend by setting a shader snippet on
the pipeline.

This splits out the cogl_path_ api into a separate cogl-path sub-library
like cogl-pango and cogl-gst. This enables developers to build Cogl with
this sub-library disabled if they don't need it which can be useful when
its important to keep the size of an application and its dependencies
down to a minimum. The functions cogl_framebuffer_{fill,stroke}_path
have been renamed to cogl_path_{fill,stroke}.
There were a few places in core cogl and cogl-gst that referenced the
CoglPath api and these have been decoupled by using the CoglPrimitive
api instead. In the case of cogl_framebuffer_push_path_clip() the core
clip stack no longer accepts path clips directly but it's now possible
to get a CoglPrimitive for the fill of a path and so the implementation
of cogl_framebuffer_push_path_clip() now lives in cogl-path and works as
a shim that first gets a CoglPrimitive and uses
cogl_framebuffer_push_primitive_clip instead.
We may want to consider renaming cogl_framebuffer_push_path_clip to
put it in the cogl_path_ namespace.

cogl-path as a noinst_LTLIBRARY before building cogl and link the code

until the start of the 1.18 cycle before splitting the code into a
separate libcogl-path.so.
This also adds shims for cogl_framebuffer_fill/stroke_path() to avoid
breaking the 1.x API/ABI.
Otherwise, if we try egl-wayland first, we get the environment

When splitting out the CoglPath api we saw that we would be left with
inconsistent drawing apis if the drawing apis in core Cogl were lumped
into the cogl_framebuffer_ api considering other Cogl sub-libraries or
that others will want to create higher level drawing apis outside of
Cogl but can't use the same namespace.
So that we can aim for a more consistent style this adds a
cogl_primitive_draw() api, comparable to cogl_path_fill() or
cogl_pango_show_layout() that's intended to replace
cogl_framebuffer_draw_primitive()
Note: the attribute and rectangle drawing apis are still in the
cogl_framebuffer_ namespace and this might potentially change but in
these cases there is no single object representing the thing being drawn
so it seems a more reasonable they they live in the framebuffer
namespace for now.
Note: the cogl_framebuffer_draw_primitive() api isn't removed by this
patch so it can more conveniently be cherry picked to the 1.16 branch so
we can mark it deprecated for a short while. Even though it's marked as
experimental api we know that there are people using the api so we'd
like to give them a chance to switch to the new api.

The plan is to remove the cogl-auto-texture apis since they hide a bit
too much from developers but currently the conformance tests depend on
these apis in numerous places.
For the conformance tests it makes some sense to continue using high
level texture apis similar to the auto-texture apis since we may want
to make broad variations to how textures are allocated as part of the
testing running if that might help exercise more code paths.
This patch copies much of the auto-texture functionality into some
slightly more special purpose utilities in test-utils.c/h. Minor changes
include being constrained to the public Cogl api and they also don't
let you catch CoglErrors and just assume they should abort on error.
