Add OML_sync_control support, along with a simple program for testing
it. This means adding support for the DRI2GetMSC, DRI2WaitMSC and
DRI2WaitSBC requests.

Support the new DRI2 protocol request, DRI2SwapBuffers, in both direct
and indirect rendering context. This request allows the display server
to optimize back->front swaps (e.g. through page flipping) and allows us
to more easily support other GLX features like swap interval and the OML
sync extension in DRI2.

Only enable verbose NoOp dispatch if DEBUG is defined
By default we generate a function per GL entry point to warn if it's
called without a context set. This is to allow the function to print
it's name in the warning. By using a generic function that doesn't print
the function name in the non-DEBUG case, we reduce libGL size from
320008 bytes to 283144 bytes (11%).
The GLUTAPI #define used in the header file to mark the font structs
visible wasn't kicking in because of the #define glutBitmap9By15 XXX
prior to #include <GL/glut.h>. High quality code... worked around by
copying the GLUTAPI specifier to the invidual C files.
The environment for building the DLL needs to be quite different from
the environment for building the programs, in order to get
the dllexport/dllimport attribute done currectly. I don't know how MinGW
managed to build the programs, but MS linker refuses to link symbols with
mismatching attributes.
This is a substantial reorganization, This particular commit enables:
- building the progs for unices platforms
- glew is now built as a shared library (it is the default, and it is
inconvenient and pointless to shift away from that default)
- all progs get built by default
Some of the demo progams legitimately need the functionality
that's disabled by WIN32_LEAN_AND_MEAN.
Instead the solution should be to define WIN32_LEAN_AND_MEAN just before
including windows.h on a case by case basis.
GLAPI on windows is more than "extern" -- it includes the --, so the
mismatch between condrender.[ch] prototypes causes "different linkage"
errors on windows.
glut: Silent the glut*_ATEXIT_HACK defined but not used warnings.
There are two ways to silent this: put inline keyword, or reimplement the
hack as a #define. inline keyword actually varies slightly with compiler
so I've opted by the latter.
Render into two color buffers (render targets). Display half of each
buffer in the window. Use different color masks for each render target.
Only enable blending for the second render target.
