[cogl] Improving Cogl journal to minimize driver overheads + GPU state changes

The Cogl journal is a mechanism Cogl uses to batch geometry resulting from
any of the cogl_rectangle* functions before sending it to OpenGL.  This aims
to improve the Cogl journal so that it can reduce the number of state
changes and draw calls we issue to the OpenGL driver and hopfully improve
performance.

Previously each call to any of the cogl_rectangle* functions would imply an
immediate GL draw call, as well as a corresponding modelview change;
material state changes and gl{Vertex,Color,TexCoord}Pointer calls.  Now
though we have tried to open the scope for batching up as much as possible
so we only have to flush the geometry either before calling glXSwapBuffers,
or when we change state that isn't tracked by the journal.

As a basic example, it's now possible for us to batch typical picking
renders into a single draw call for the whole scene.

Some key points about this change:
- We now perform transformations of quads in software (except for long runs of
  text which continue to use VBOs)
    * It might seem surprising at first, but when you consider that so many
      Clutter actors are little more than textured quads and each actor
      typically implies a modelview matrix change; the costs involved in
      setting up the GPU with the new modelview can easily out weigh the cost
      of simply transforming 4 vertices.
- We always use Cogl's own client side matrix API now.
    * We found the performance of querying the OpenGL driver for matrix state
      was often worse than using the client matrix code, and also - discussing
      with Mesa developers - agreed that since khronos has essentially
      deprecated the GL matrix API (by removing it from OpenGL 3 and
      OpenGL-ES 2) it was appropriate to take full responsibility for all our
      matrix manipulation.
- Developers should avoid modifying materials mid-scene.
    * With the exception of material color changes, if you try and modify a
      material that is referenced in the journal we will currently force a
      journal flush. Note: you can assume that re-setting the same value for
      a material property won't require a flush though.
- Several new --cogl-debug options have been added
    * "disable-batching" can be used to identify bugs in the way that the
      journal does its batching; of could this shouldn't ever be needed :-)
    * "disable-vbos" can be used to test the VBO fallback paths where we
      simply use malloc()'d buffers instead.
    * "batching" lets you get an overview of how the journal is batching
      your geometry and may help you identify ways to improve your
      application performance.
    * "journal" lets you trace all the geometry as it gets logged in the
      journal, and all the geometry as its flushed from the journal.
      Obviously an inconsistency can identify a bug, but the numbers may
      help you verify application logic too.
    * "disable-software-transform" as implied will instead use the driver
      /GPU to transform quads by the modelview matrix.
    Although committed separately a --clutter-debug=nop-picking option was
    also added that lets you remove picking from the equation, which can
    sometimes help make problem analysis more deterministic.

*
* Note: this doesn't help you modify the behaviour of Cogl drawing functions

* but if you are trying to do something like:
* <programlisting>
* {
* - setup some OpenGL state.
* - draw using OpenGL (e.g. glDrawArrays() )
* - reset modified OpenGL state.
* - continue using Cogl to draw

* This function will flush all batched primitives, and subsequently flush
* all internal Cogl state to OpenGL as if it were going to draw something
* itself.
*
* The result is that the OpenGL modelview matrix will be setup; the state
* corresponding to the current source material will be set up and other world
* state such as backface culling, depth and fogging enabledness will be sent
* to OpenGL.
*
* Note: no special material state is flushed, so if you want Cogl to setup a
* simplified material state it is your responsibility to set a simple source
* material before calling cogl_begin_gl. E.g. by calling
* cogl_set_source_color4ub().
*
* Note: It is your responsibility to restore any OpenGL state that you modify
* to how it was after calling cogl_begin_gl() if you don't do this then the
