partition as if it were on the command line. Fetch FreeBSD-LoaderEnv UEFI enviornment variable. If set, read in loader environment variables from it. Otherwise read in /efi/freebsd/loader.env. Both are read relative to the device loader.efi loaded from (they aren't full UEFI device paths) Next fetch FreeBSD-NextLoaderEnv UEFI environment variable. If present, read the file it points to in as above and delete the UEFI environment variable so it only happens once. This lets one set environment variables in the bootloader. Unfortunately, we don't have all the mechanisms in place to parse the file, nor do we have the magic pattern matching in place that loader.conf has. Variables are of the form foo=bar. No quotes are supported, so spaces aren't allowed, for example. Also, variables like foo_load=yes are intercepted when we parse the loader.conf file and things are done based on that. Since those aren't done here, variables that cause an action to happen won't work. Reviewed by: bcran Differential Revision: https://reviews.freebsd.org/D20016
