While looking to upgrade to zlib-1.2.5, the current mondo merge of multiple files into a single was making things way more difficult than it should have been. Hard to pick out what has been changed to port it to U-Boot, been removed as useless, and bug fixes added after the fact. So split the single file up into the original file names, and merge non-essential changes back from the original tree (for some reason, style in code in a bunch of places was changed to U-Boot style even though this isn't "U-Boot" code). The original build style is retained -- we have a single zlib.c that includes all the other files, and that is the only file we compile. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
