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

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

Stop using sbrk in csh. This is a legacy interface and its use within csh
is invalid. It is used to find the size of allocated memory. As malloc may
allocate memory with mmap it will fail to take this memory into account.

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.

Let csh(1) use utmpx instead of utmp.

csh allows you to monitor the utmp(x) file to monitor certain user
logins. Unfortunately it needs to directly stat() this file. I don't
want to break this module , but eventually it shouldn't do that. The
idea of the getutxent(3) API is to hide file access.

Enable NLS catalog of csh(1).
The tcsh 6.14 uses libiconv to convert catalogs to appropriate charset
dynamically. However, we don't have libiconv in our tree. So, I made
some hack to load libiconv dynamically. If libiconv is available, you
can use catalogs for more locales than the locales which catalog is
actually installed.
To use this feature, you need to symlink catalogs to appropriate
locales. You can do this by installing ports/shells/tcsh_nls.

Define HAVE_STRUCT_UTMP_UT_HOST in order for the REMOTEHOST environment
variable to show up correctly.

Note: This is really a bug with the stock tcsh configure.in script not
including <sys/types.h> before <utmp.h>. But, since config.h is maintained
separate from the contrib sources, this is the correct fix.

Noticed by: ache

Add the config.h resulting from running the configure script.

Note: the contents of this file has changed between 6.13 and 6.14.
The old contents of this file has been repocopied to config_p.h.

Fix typo

Use LC_MESSAGES locale category instead of value of LANG environment variable
while opening of tcsh's message catalog. It gives us more flexibility, and
do not change current behaviour (since we call setlocale() here)
