sys-firmware/intel-microcode: rewrite to use iucode_tool.
- Use the Intel upstream 'iucode_tool' to process all of the input microcode, from both the text-format microcode.dat file and other inputs, then generate a clean set of split outputs & optionally also initramfs output. - Allows easy inclusion of any future split-ucode releases for single CPUs. - No longer uses intel-microcode2ucode.c from $FILESDIR. - Expert users can use the new MICROCODE_SIGNATURES variable to install only a subset of microcodes on their system, as requested by bug 643786. - Avoids accidently bloated split-ucode files per bug #644100. - USE=monolithic is no longer supported, please see iucode_tool for any fallback. - USE=initramfs now writes to /boot/intel-uc.img (8.3-safe naming). Fixes: https://bugs.gentoo.org/643786 Fixes: https://bugs.gentoo.org/644100 Package-Manager: Portage-2.3.16, Repoman-2.3.6 Signed-off-by: Robin H. Johnson <robbat2@gentoo.org>
