185630085c Add -Wmissing-declarations to maintainer flags and fix problems
This option to GCC makes it give a warning whenever a global function
is defined without a declaration. This should catch cases were we've
defined a function but forgot to put it in a header. In that case it
is either only used within one file so we should make it static or we
should declare it in a header.

The following changes where made to fix problems:

• Some functions were made static

• cogl-path.h (the one containing the 1.0 API) was split into two
  files, one defining the functions and one defining the enums so that
  cogl-path.c can include the enum and function declarations from the
  2.0 API as well as the function declarations from the 1.0 API.

• cogl2-clip-state has been removed. This only had one experimental
  function called cogl_clip_push_from_path but as this is unstable we
  might as well remove it favour of the equivalent cogl_framebuffer_*
  API.

• The GLX, SDL and WGL winsys's now have a private header to define
  their get_vtable function instead of directly declaring in the C
  file where it is called.

• All places that were calling COGL_OBJECT_DEFINE need to have the
  cogl_is_whatever function declared so these have been added either
  as a public function or in a private header.

• Some files that were not including the header containing their
  function declarations have been fixed to do so.

• Any unused error quark functions have been removed. If we later want
  them we should add them back one by one and add a declaration for
  them in a header.

• _cogl_is_framebuffer has been renamed to cogl_is_framebuffer and
  made a public function with a declaration in cogl-framebuffer.h

• Similarly for CoglOnscreen.

• cogl_vdraw_indexed_attributes is called
  cogl_framebuffer_vdraw_indexed_attributes in the header. The
  definition has been changed to match the header.

• cogl_index_buffer_allocate has been removed. This had no declaration
  and I'm not sure what it's supposed to do.

• CoglJournal has been changed to use the internal CoglObject macro so
  that it won't define an exported cogl_is_journal symbol.

• The _cogl_blah_pointer_from_handle functions have been removed.
  CoglHandle isn't used much anymore anyway and in the few places
  where it is used I think it's safe to just use the implicit cast
  from void* to the right type.

• The test-utils.h header for the conformance tests explicitly
  disables the -Wmissing-declaration option using a pragma because all
  of the tests declare their main function without a header. Any
  mistakes relating to missing declarations aren't really important
  for the tests.

• cogl_quaternion_init_from_quaternion and init_from_matrix have been
  given declarations in cogl-quaternion.h

be237cc2b7 renderer: Adds getters/setters for driver preference
This adds api for explicitly choosing what underlying driver cogl should
use internally for rendering as well as api for querying back what
driver is actually in use.

0f33c942f2 kms: gracefully handle NULL save_state at cleanup
If we failed to save any crtc state then we skip trying to restore the
old state at cleanup.

1a638b6fd6 kms: Adds api to get at the kms file descriptor
This adds a cogl_kms_renderer_get_kms_fd() function that lets developers
access the kms file descriptor being used for controlling the kernel
mode setting.

a6b1f55546 kms: Don't use egl_surface_width/height
The egl_surface_width/height properties in CoglDisplayEGL were
accidentally being conditionally defined depending on KMS
support. They are not necessary because CoglDisplayKMS also already
stores the width/height and this was just copied over to the EGL
dipslay.

dd75926c1a egl: Split out the KMS winsys as overrides of the EGL winsys
Instead of having #ifdefs to hook into the normal EGL winsys, the KMS
winsys now overrides any winsys functions that it wants. Where the
winsys wants to hook into a point within a function provided by the
EGL winsys there is a EGL-platform vtable which gets set on the EGL
renderer data during renderer_connect. The KMS-specific data on all of
the structures is now allocated separately by the KMS winsys and is
pointed to by a new 'platform' pointer in the EGL data.

a1e1527b69 Add a separate winsys vtable for each EGL platform
Instead of just having an "EGL" renderer, there is now a separate
winsys for each platform. Currently they just directly copy the vtable
for the EGL platform so it is still only possible to have one EGL
platform compiled into Cogl. However the intention is that the
winsys-specific code for each platform will be moved into override
functions in the corresponding platform winsys.
