Don't dereference an unitialised pointer in _cogl_container_of

The previous implementation was dereferencing the sample pointer in
order to get the offset to subtract from the member pointer. The
resulting value is then only used to get a pointer to the member in
order to calculate the offset so it doesn't actually read from the
memory location and shouldn't cause any problems. However this is
probably technically invalid and could have undefined behaviour. It
looks like clang takes advantage of this undefined behaviour and
doesn't actually offset the pointer. It also generates a warning when
it does this.

This patch splits the _cogl_container_of macro into two
implementations. Previously the macro was always used in the list
iterator macros like this:

SomeType *sample = _cogl_container_of(list_node, sample, link)

Instead of doing that there is now a new macro called
_cogl_list_set_iterator which explicitly assigns to the sample pointer
with an initial value before assigning to it again with the real
offset. This redundant initialisation gets optimised out by compiler.

The second macro is still called _cogl_container_of but instead of
taking a sample pointer it just directly takes the type name. That way
it can use the standard offsetof macro.

Allocate immediately in _cogl_egl_texture_2d_new_from_image

The _cogl_egl_texture_2d_new_from_image function has a CoglError
argument which implies that it is unlike the other texture
constructors and returns errors immediately rather than having a
delayed-allocation mechanism. cogl_wayland_texture_2d_new_from_buffer
which calls it is also like this. We can't rely on delayed-allocation
semantics for this without changing the applications because the
texture needs to be allocated before the corresponding EGLImage is
destroyed. This patch just makes it immediately allocate.

A better patch might be to remove the error argument to make it
obvious that there are delayed-allocation semantics and then fix all
of the applications.

This was breaking Cogland and Mutter.

kms: include stddef.h before drm.h

Not doing so leads to the following error, if stddef.h is not included
indirectly through EGL headers:

| libdrm/drm.h:132:2: error: unknown type name 'size_t'
|   size_t name_len;   /**< Length of name buffer */
