This is the fist of two series of patches to address: https://bugs.freedesktop.org/show_bug.cgi?id=84566
The idea is that we have a lot of format conversion code scattered through different files in the repository, a lot of that is redundant / duplicated, so this intends to address that issue. The goal of this first series is to address auto-generation of our pack/unpack functions (format_pack.c and format_unpack.c). Currently, we have a ton of hand-coded pack/unpack functions for lots of formats, but we can auto-generate most of that code instead, so this series handles this. This is based on initial work by Jason Ekstrand. Tested on i965, classic swrast and gallium (radeon, nouveau, llvmpipe) without regressions. For software drivers we worked with a trimmed set of piglit tests (related to format conversion), ~5700 tests selected with the following filter: -t format -t color -t tex -t image -t swizzle -t clamp -t rgb -t lum -t pix -t fbo -t frame Summary of the patches: * Patches 1-7 are general fixes to the current code that were found while working on this. * Patches 8-16 implement auto-generation of pack/unpack functions. * Patches 17-20 make use of the auto-generated pack/unpack functions in various places to simplify the current code. Notice that some of the fixes in patches 1-7 will become obsolete as soon as we auto-generate the pack/unpack functions, but we thought it would make sense to keep them in the patch set anyway since we started from that base and they should be correct fixes to the currently existing code.
