Mark Johnston 6026dcd7ca Add support for zstd-compressed user and kernel core dumps. ... This works similarly to the existing gzip compression support, but zstd is typically faster and gives better compression ratios. Support for this functionality must be configured by adding ZSTDIO to one's kernel configuration file. dumpon(8)'s new -Z option is used to configure zstd compression for kernel dumps. savecore(8) now recognizes and saves zstd-compressed kernel dumps with a .zst extension.
