Remove ancient SCCS tags from the tree, automated scripting, with two
minor fixup to keep things compiling. All the common forms in the tree
were removed with a perl script.

gcore: add option to dump core using kernel facility

-k switch causes gcore to use ptrace(PT_COREDUMP) instead of manually
reading process memory and constructing the core.

Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

Remove gcore's -s option.

It has no effect and is always implicitly set since ptrace(2) stops the
target process.

Start sentences on a new line to ease life for translators. Tweak the
wording in a few places.

Fix the way the segments are included in the gcore outputs (with the
default invokation):
- Right now if segments are not writable are not included. Remove this.
- Right now if a segment is mapped with NOCORE the check is not honoured.
Change this by checking the newly added flag, from libutil,
KVME_FLAG_NOCOREDUMP.

Besides that, add a new flag (-f) that forces a 'full' dump of all the
segments excluding just the malformed ones. This might be used very
carefully as, among the reported segments, there could be memory
mapped areas that could be vital to program execution.

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.

MFC r199805:
Change gcore in order to get rid of the procfs support and use FreeBSD's
specific interfaces. Main changes:
- now gcore recognizes threads within the the process and handle dumps on
a thread scope
- the process to be analyzed should be stopped while gcore runs
- gcore may not work with processes that are being debugged with gdb or
truss
- ptrace may let interruptible calls to return EINTR, thus dirtying
signals handling within the process

Change gcore in order to get rid of the procfs accesses and use FreeBSD's
specific sysctls and ptrace interfaces.
This change switches a bit gcore POLA that is summarized here:
- now gcore can recognize threads within the process and handle dumps
on thread-scope
- the process to be analyzed will be stopped during its gcore run
- gcore may not work with processes which are actively being analyzed
by gdb or truss
- the ptrace interface may cause syscalls to return EINTR, thus
interferring with signals handling within the process

Side note: <janitor task> the interface can be further lifted in order to
get rid of the very last procfs interfaces remnants and made more
suitable for copying with sysctl/ptrace interface </janitor task>.

$Id$ -> $FreeBSD$

Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.
