These match their alpha counterparts, apart from not setting the
alpha bit. This allows our internal mashinery to more easily
distinguish whether we need a slow alpha-pass during rendering or not.

In order to support the DRM formats DRM_FORMAT_ABGR16161616F and
friends, as well as the wl_shm formats WL_SHM_FORMAT_ABGR16161616F and
friends, cogl needs to have knowledge about said formats too.
We don't have a software implementation of the half point data types
however, so the pack/unpack methods remain unimplemented. We don't need
them for now, so it's not crucial that we add them.
For the GLES2 driver, currently only two formats are supported, and
since we don't currently have pack/unpack implementations, the other
formats will for now remain unsupported, until we have a half float
implementation.

Just like libmutter-clutter, and libmutter, mark exported symbols with
an COGL_EXPORT macro. This removes the .map and .map.in files previously
used, containing a list of semi private symbols. This symbol was out of
date, i.e. pointed to non-existing symbols, and was also replaced with
COGL_EXPORT macros.
unit_test_* symbols are exported by the help of the unit test defining
macro. test_* symbols are no longer supported as it proved unnecessary.

As we will start adding support for more pixel formats, we will need to
define a notion of planes. This commit doesn't make any functional
change, but starts adding the idea of pixel formats and how they (at
this point only theoretically) can have multple planes.
Since a lot of code in Mutter assumes we only get to deal with single
plane pixel formats, this commit also adds assertions and if-checks to
make sure we don't accidentally try something that doesn't make sense.

By providing an (internal) table to map `CoglPixelFormat`s to their
respective properties we will be able to get rid of the unusual enum
values in the future. This is something we will need once we want to
have support for more pixel formats (such as YUV-based formats).
As an extra feature, we provide a `to_string()` method, which is quite
useful for debugging purposes (rather than deciphering enum values).

We're going to add some features and extra code to CoglPixelFormat, so
it's much nicer to have it in once place. Notice also that it doesn't
make sense that e.g. `_cogl_pixel_format_get_bytes_per_pixel()` were in
a private header, since they were being exported anyway.
