Mark Johnston 78f57a9cde Generalize the gzio API. ... We currently use a set of subroutines in kern_gzio.c to perform compression of user and kernel core dumps. In the interest of adding support for other compression algorithms (zstd) in this role without complicating the API consumers, add a simple compressor API which can be used to select an algorithm. Also change the (non-default) GZIO kernel option to not enable compressed user cores by default. It's not clear that such a default would be desirable with support for multiple algorithms implemented, and it's inconsistent in that it isn't applied to kernel dumps.
