Remove $FreeBSD$: one-line .c comment pattern

Remove /^/[*/]\s*\$FreeBSD\$.*\n/

People porting FreeBSD to new architectures ought not have to
implement a deprecated FPU control interface in addition to the
standard one. To make this clearer, further deprecate ieeefp.h
by not declaring the function prototypes except on architectures
that implement them already.

Currently i386 and amd64 implement the ieeefp.h interface for
compatibility, and for fp[gs]etprec(), which doesn't exist on
most other hardware. Powerpc, sparc64, and ia64 partially implement
it and probably shouldn't, and other architectures don't implement it
at all.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

- Import the HEAD csup code which is the basis for the cvsmode work.

o Move the contents of <machine/floatingpoint.h> over to
<machine/ieeefp.h> where it belongs.
o Remove the i386 specific inclusion of <machine/floatingpoint.h>
from <ieeefp.h>, now that including <machine/ieeefp.h> is enough
for all architectures.
o Allow <machine/ieeefp.h> to inline the functions exposed by the
headers by checking for _IEEEFP_INLINED_ in the MI header. When
defined, prototypes are not given and it is assumed that the MD
headers, when inlining only a subset of the functions provide
prototypes for the functions not being inlined.

Tested with: make release.

Breath deep and take __P out of the system include files.

# This appears to not break X11, but I'm having problems compiling the
# glide part of the server with or without this patch, so I can't tell
# for sure.

Finish moving all IEEE fp types to be the same on all arch's.

fp_except => fp_except_t for consistancy with the i386 and the tradition
C methoid of nameing types.

Allow fpsetmask(3) and friends to be used from a C++ program on the Alpha.

Use __i386__ instead of i386 in an ifdef.

Implement fpsetmask() and other fp*() functions. Programs should use

#include <ieeefp.h>

to access these functions instead of the i386 specific

#include <machine/floatingpoint.h>
