Part I: Update extended attribute API and ABI:
o Modify the system call syntax for extattr_{get,set}_{fd,file}() so
as not to use the scatter gather API (which appeared not to be used
by any consumers, and be less portable), rather, accepts 'data'
and 'nbytes' in the style of other simple read/write interfaces.
This changes the API and ABI.
o Modify system call semantics so that extattr_get_{fd,file}() return
a size_t. When performing a read, the number of bytes read will
be returned, unless the data pointer is NULL, in which case the
number of bytes of data are returned. This changes the API only.
o Modify the VOP_GETEXTATTR() vnode operation to accept a *size_t
argument so as to return the size, if desirable. If set to NULL,
the size will not be returned.
o Update various filesystems (pseodofs, ufs) to DTRT.
These changes should make extended attributes more useful and more
portable. More commits to rebuild the system call files, as well
as update userland utilities to follow.

Begin committing support for Mandatory Access Control and extensible
kernel access control. The MAC framework permits loadable kernel
modules to link to the kernel at compile-time, boot-time, or run-time,
and augment the system security policy. This commit includes the
initial kernel implementation, although the interface with the userland
components of the operating system is still under work, and not all
kernel subsystems are supported. Later in this commit sequence,
documentation of which kernel subsystems will not work correctly with
a kernel compiled with MAC support will be added.
Introduce two node vnode operations required to support MAC. First,
VOP_REFRESHLABEL(), which will be invoked by callers requiring that
vp->v_label be sufficiently "fresh" for access control purposes.
Second, VOP_SETLABEL(), which be invoked by callers requiring that
the passed label contents be updated. The file system is responsible
for updating v_label if appropriate in coordination with the MAC
framework, as well as committing to disk. File systems that are
not MAC-aware need not implement these VOPs, as the MAC framework
will default to maintaining a single label for all vnodes based
on the label on the file system mount point.
