Create gptboot.efi This is a primary boot loader that is intended to implement the gptboot partition selection algorithm just like we did for BIOS booting. While the preferred method for UEFI is to use the UEFI Boot Manager protocol, there are situations where that can't be done: some BIOS makers interfere with the protocol in unhelpful ways, there's a new standard for a zero variable write from the client OS, and finally for USB drives that might be mobile between systems with multiple partitions there needs to be a media stable way to select.

gptboot.efi: Add man page Add a man page for gptboot.efi. Describe when and how to use this as it differs from the BIOS cases. Include cross reference for the preferred method described in efibootmgr(8) as well as cross links in both gptboot(8) and gptboot.efi(8) to the other. This man page was heavily copied from the gptboot.8 man page by Warren Block. They are different enough to need separate man pages for clarity, but there's enough similarity that I worry about the duplication. In the really long term, gptboot(8) will disappear, so having the same info here will help when that day comes. In the short to medium term, the information is likely to not change in gptboot(8) and any changes to gptboot.efi(8) will be easier to make in a separate copy. loader.efi(8) needs a complete rewrite from scratch, otherwise I'd have referenced gptboot.efi(8) from there.

loader: remove libsa/crc32.c and use version from zlib we have crc32(const void *, size_t) in libsa. Unfortunately zlib has crc32(long, const unigned char *, unsigned) and we have conflict. Since we do build libsa with zlib, we can use zlib version instead. Reviewed by: allanjude Differential Revision: https://reviews.freebsd.org/D24068
