Update to the latest Bochs BIOS
Update the PC BIOS to the latest version, split out the patches into patch series, and update the README to point to the new location of the Bochs BIOS source tree. Also update the gitignore to allow the patch queue directory to be used. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6077 c046a42c-6fe2-441c-8c8c-71466251a162
