Hi all,

This patch set imports the upstream zstd library, adds zstd support to the
btrfs module, and adds a test case. I've also tested the patch set by storing
my boot partition in btrfs with and without zstd compression and rebooting.

Best,
Nick Terrell

Changelog:

v1 -> v2:
- Switch to upstream zstd-1.3.6 and drop all the local patches.
- Fix comments from Daniel Kiper.

v2 -> v3:
- Remove an extra file accidentally included in the first patch.
- Use grub_error() to set grub_errno in grub_btrfs_zstd_decompress().
- Fix style and formatting comments.

v3 -> v4:
- Put zstd in its own module.
- Update commit messages.
- Use attribute unused.
- Rebase on top of RAID patchset.

v4 -> v5:
- Add change lists to the top of the commit messages.
- Add a header to zstd's moudle.c file.
- Clarify where zstd's dependencies are coming from.
- Add module.c to Makefile.util.def.
- Clarify some error logging.
- Explain why I changed lzo's include.

v5 -> v6:
- Formatting changes
