This is the start of the kernel_interface API that allows callers to
specify a buffer, a file path, or a file descriptor that should be
copied to the proper kernel interface for loading, replacing, or
removing in-kernel policies.
Support exists for reading from a file path or file descriptor into a
buffer and then writing that buffer to the appropriate apparmorfs
interface file.
An aa_kernel_interface_write_policy() function is also provided for
callers that want to route a buffer to an arbitrary file descriptor
instead of to an apparmorfs file. This is useful when an admin instructs
apparmor_parser to write to stdout or a file.
Additionally, it removes some parser-specific globals from the
kernel_interface.c file, such as OPTION_{ADD,REPLACE,REMOVE}, in
preparation for moving the code into a library.
