1000c80444 cogl: declare experimental symbols consistently
We had several different ways of exposing experimental API, in one case
the symbols had no special suffix, in two other ways the symbols were
given an _EXP suffix but in different ways.

This makes all experimental API have an _EXP suffix which is handled
using #defines in the header so the prototypes in the .c and .h files
don't have the suffix.

The documented reason for the suffix is so that anyone watching Cogl for
ABI changes who sees symbols disappear will hopefully understand what's
going on.

fa22ee0e8d math: Adds an experimental cogl_vector3_* API
This adds a math utility API for handling 3 component, single precision
float vectors with the following; mostly self explanatory functions:

cogl_vector3_init
cogl_vector3_init_zero
cogl_vector3_equal
cogl_vector3_equal_with_epsilon
cogl_vector3_copy
cogl_vector3_free
cogl_vector3_invert
cogl_vector3_add
cogl_vector3_subtract
cogl_vector3_multiply_scalar
cogl_vector3_divide_scalar
cogl_vector3_normalize
cogl_vector3_magnitude
cogl_vector3_cross_product
cogl_vector3_dot_product
cogl_vector3_distance

Since the API is experimental you will need to define
COGL_ENABLE_EXPERIMENTAL_API before including cogl.h if you want to use
the API.
