Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Add the BSD-licensed Citrus iconv to the base system with default off
setting. It can be built by setting the WITH_ICONV knob. While this
knob is unset, the library part, the binaries, the header file and
the metadata files will not be built or installed so it makes no impact
on the system if left turned off.

This work is based on the iconv implementation in NetBSD but a great
number of improvements and feature additions have been included:

- Some utilities have been added. There is a conversion table generator,
which can compare conversion tables to reference data generated by
GNU libiconv. This helps ensuring conversion compatibility.
- UTF-16 surrogate support and some endianness issues have been fixed.
- The rather chaotic Makefiles to build metadata have been refactored
and cleaned up, now it is easy to read and it is also easier to add
support for new encodings.
- A bunch of new encodings and encoding aliases have been added.
- Support for 1->2, 1->3 and 1->4 mappings, which is needed for
transliterating with flying accents as GNU does, like "u.
- Lots of warnings have been fixed, the major part of the code is
now WARNS=6 clean.
- New section 1 and section 5 manual pages have been added.
- Some GNU-specific calls have been implemented:
iconvlist(), iconvctl(), iconv_canonicalize(), iconv_open_into()
- Support for GNU's //IGNORE suffix has been added.
- The "-" argument for stdin is now recognized in iconv(1) as per POSIX.
- The Big5 conversion module has been fixed.
- The iconv.h header files is supposed to be compatible with the
GNU version, i.e. sources should build with base iconv.h and
GNU libiconv. It also includes a macro magic to deal with the
char ** and const char ** incompatibility.
- GNU compatibility: "" or "char" means the current local
encoding in use
- Various cleanups and style(9) fixes.

Remove the Berkeley clause 3's.
Add a few $FreeBSD$

Remove the current directory from _PATH_STDPATH.

Also un-split _PATH_STDPATH for grepability.
While I'm here, fix other style bugs reported to me.

No need to wrap _PATH_SYSPATH. It makes it harder to grep(1) for its
value. (also unwrapping better matches existing style)

Add _PATH_FWMEM for libkvm.

Define _PATH_MKSNAP_FFS and use it in dump(8) instead of assuming
that mksnap_ffs(8) can be found using the current $PATH.

Add /rescue bits. This basically encompasses all of bin and sbin along
with a couple of bits from usr.bin in a crunchgen'd binary.

Move path definitions to include/paths.h. This makes it easier to override
these definitions in the /rescue case.

Convert fsck and mount to using execvP to find fsck_foo and mount_foo.
This simplifies the code path and makes the default path easy to override

Move _PATH_LOCALE to place where it really belongs to (rune.h -> paths.h)

Remove _PATH_DEVDB

Centralize _PATH_* definitions.

Dynamic object dependency mapping: libmap.

This is an optional feature, disabled by default.

This will be useful to people testing the various POSIX threading
libraries under -CURRENT but can easily serve other needs.

Correct _PATH_RCP to be /bin/rcp, not /usr/bin/rcp.

Move _PATH_WALL from dump and shutdown's local pathnames.h to paths.h.

Add some more commonly-used directories and files.

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

# This appears to not break X11, but I'm having problems compiling the

o Improve consistency of style by fixing tabs around _PATH_AUTHCONF.

o Introduce _PATH_CAPABILITY and _PATH_CAPABILITY_DB to the system
path set. These files will hold per-user capability information.

Move _PATH_DEFTAPE to <paths.h> to remove all the duplication of definitons,
and remove leading `r'(aw) from it.

Add `_PATH_DEVZERO'.
Use _PATH_* where where possible.

Move nologin from /etc to /var/run. This means one less file that has
to be written to /etc.

The only essential change is in paths.h, so any third-party software
written correctly will pick it up in the next rebuild.

Get rid of _PATH_UNIX completely; use getbootfile(3) instead.

DANGER WILL ROBINSON!
_PATH_UNIX is currently defined as the literal string "don't use this".
I am of two minds about this myself, but wanted to get something into the

Update the Makefile to work correctly when copying and/or symlinking
/usr/include.

Make comment about mp.h missing and remove it from the list of files.
Fix installation of ufs include files as this is now a tree ufs/{ffs,lfs,
mfs,ufs}.

Make setting of SHARED optional by makeing it SHARED?=.

Comment out installation of X11 includes since it does not work
for XFree86 until we get XFree86 to install as /usr/X11.

Update _PATH_UNIX to be /kernel. Remove /usr/{contrib,old}/bin from
_PATH_STDPATH.
