svga: fix incorrect memcpy src in svga_buffer_upload_piecewise()

As we march over the source buffer we're uploading in pieces, we
need to memcpy from the current offset, not the start of the buffer.
Fixes graphical corruption when drawing very large vertex buffers.

mesa: Don't return any data for GL_SHADER_BINARY_FORMATS

We return 0 for GL_NUM_SHADER_BINARY_FORMATS, so
GL_SHADER_BINARY_FORMATS should not write any data to the application
buffer.

Fixes piglit test 'arb_get_program_binary-overrun shader'.

r300g: remove unused function r300_lacks_vertex_textures
r600g: remove an assertion causing a crash at context cleanup

Compute samplers are advertised, but not implemented.
I think that's intentional.
r600g: texture offsets for non-TXF instructions

All texture instructions can use offsets, not just TXF. Offsets into
the literals array were wrong, too.

haiku: Build Haiku's libGL from within Mesa

* This in essence means that Mesa would be
  taking control of Haiku's OpenGL kit.
* This works by dispatching renderers from the
  OpenGL add-ons directory
haiku: Add first Haiku renderer (softpipe)

* This shared library gets parsed by the
  system as a system "add-on"
haiku: Correct Haiku softpipe library

* Use LoadableModule vs SharedLibrary
haiku: Drop haiku-softpipe.c; fix extern C

* It isn't needed any longer as we're
  moving in the code that called it.
* The winsys code is C, so make sure
  we include the header in the extern C
haiku: Clean up code, use target-helpers

* Thanks for the help xexaxo!
haiku: Ensure correct libraries are referenced.
