This removes a lot of complexity, since we basically just reserve
space on a retrieval of a label, and pass around strings. Two new
elements: (1) consumers of the API must now declare what label
elements they are interested in retrieving, or (2) rely on the default
provided in a new configuration file, mac.conf.

revision, we have only policy-agnostic code in libc and the base
kernel.

label updates. Biba and MLS already supported this. This permits the
userland library to submit relative updates on MAC labels, rather
than submitting an entire label to replace the current label. This
also requires changes to the MAC modules, which are forthcoming.

Extensions to libc to provide basic MAC label manipulation facilities
for userland. These interface will be replaced in the next month
or two with more flexible interfaces, but provide sufficient support
to allow use of the Biba and MLS policies for user applications.

the extattr calls are not strictly POSIX.1e, POSIX.1e wasn't
strictly ever approved, so I think that's OK.

- lowercase Nd argument
- mark function arguments with Fa
- mark defined values with Dv
- simply copying POSIX text for RETURN VALUES and ERRORS sections is not
always a good idea. POSIX uses the word "shall" indicating the behavior
the correct implementation should follow.

utility functions which convert between string namespace names and
numeric constants used by the interface. Right now, two namespaces
are supported, EXTATTR_NAMESPACE_SYSTEM ("system") and
EXTATTR_NAMESPACE_USER ("user"). These functions are used by
various userland EA utilities, rather than hard coding the routines
all over the place.

o Rename internal library functions so that they are prefixed with
_posix1e or _POSIX1E, removing them from the application namespace (and
