Changes

Removed all DRI drivers that did not support DRI2. Specifically, - i810, mach64, mga, r128, savage, sis, tdfx, and unichrome were - removed.
Removed support for BeOS.
Removed the obsolete (and unmaintained) Windows "gldirect" and - "ICD" drivers.
Removed the linux-fbdev software driver.
Removed all remnants of paletted texture support. As required by - desktop OpenGL, GL_COLOR_INDEX data can still be uploaded - to a color (e.g., RGBA) texture. However, the data cannot be stored - internally as color-index.
Removed support for GL_APPLE_client_storage extension.
Removed the classic Mesa r300 and r600 drivers, which are superseded - by the gallium drivers for this hardware.
Removed the dead Gallium i965, cell and failover drivers, which were - either broken and with nobody in sight to fix the situation or - deprecated.
