The header guard for cogl-texture-2d-private.h was
__COGL_TEXTURE_2D_H. This would conflict with the header guard for
cogl-texture-2d.h except there a small typo ('TEXURE') so that it
was subtly different. This fixes them both to make more sense.

The coding style has for a long time said to avoid using redundant glib
data types such as gint or gchar etc because we feel that they make the
code look unnecessarily foreign to developers coming from outside of the
Gnome developer community.
Note: When we tried to find the historical rationale for the types we
just found that they were apparently only added for consistent syntax
highlighting which didn't seem that compelling.
Up until now we have been continuing to use some of the platform
specific type such as gint{8,16,32,64} and gsize but this patch switches
us over to using the standard c99 equivalents instead so we can further
ensure that our code looks familiar to the widest range of C developers
who might potentially contribute to Cogl.
So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this
switches all Cogl code to instead use the int{8,16,32,64}_t and
uint{8,16,32,64}_t c99 types instead.
Instead of gsize we now use size_t
For now we are not going to use the c99 _Bool type and instead we have
introduced a new CoglBool type to use instead of gboolean.

This adds public constructors which take a CoglBitmap to all primitive
texture types. This constructor should be considered the canonical
constructor for initializing the texture with data because it should
be possible to wrap any type of data in a CoglBitmap. Having at least
this single constructor avoids the need to have an explosion of
constructors such as new_from_data, new_from_pixel_buffer and
new_from_file etc.
The already available internal bitmap constructor for CoglTexture2D
has had its flags parameter removed under the assumption that flags do
not make sense for primitive textures. The meta constructor
cogl_texture_new_from_bitmap now just explicitly calls set_auto_mipmap
after constructing the texture depending on the value of the
COGL_TEXTURE_NO_AUTO_MIPMAP flag.

Because the wayland-client-protocol.h header defines symbols that
collide with the wayland-server-protocol.h header we allow applications
to explicitly ensure that they are only including one at a time by
exposing corresponding <cogl/cogl-wayland-client.h> and
<cogl/cogl-wayland-server.h> headers. This also adds a missing guard to
cogl-texture-2d.h that it isn't included directly.

Currently features are represented as bits in a 32bit mask so we
obviously can't have more than 32 features with that approach. The new
approach is to use the COGL_FLAGS_ macros which lets us handle bitmasks
without a size limit and we change the public api to accept individual
feature enums instead of a mask. This way there is no limit on the
number of features we can add to Cogl.
Instead of using cogl_features_available() there is a new
cogl_has_feature() function and for checking multiple features there is
cogl_has_features() which takes a zero terminated vararg list of
features.
In addition to being able to check for individual features this also
adds a way to query all the features currently available via
cogl_foreach_feature() which will call a callback for each feature.
Since the new functions take an explicit context pointer there is also
no longer any ambiguity over when users can first start to query
features.

All our experimental Cogl symbols have a corresponding #define to add
"_EXP" to the end of the symbol name, but those defines are often
positioned right after the corresponding gtk-doc comment and before
the symbol definition which means the generated documentation ends up
refering to the define and not the real definition. This tidies up
cogl-texture-2d.h and moves all the defines to be be before the gtk-doc
comments.

This adds internal API to be able to wrap a wayland buffer as a
CoglTexture2D. There is a --enable-wayland-egl-server option to decide
if Cogl should support this feature and potentially any EGL based winsys
could support this through the EGL_KHR_image_base and
EGL_WL_bind_display extensions.
This exposes a CoglTexture2D typedef and adds the following experimental
API:
cogl_is_texture_2d
cogl_texture_2d_new_with_size
cogl_texture_2d_new_from_data
cogl_texture_2d_new_from_foreign
Since this is experimental API you need to define
COGL_ENABLE_EXPERIMENTAL_API before including cogl.h.
Note: With these new entrypoints we now expect a CoglContext pointer to
be passed in, instead of assuming there is a default context. The aim is
that for Cogl 2.0 we won't have a default context so this is a step in
that direction.
