* kern/env.c (grub_env_context_open): Added an argument to specify
    whether a new context inherits exported variables from current
    one. This is useful when making a sandbox to interpret a config
    file.
    All callers updated.

    * include/grub/env.h (grub_env_context_open): Updated the prototype.
