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.

+#     Column #2 is the corresponding Unicode (in hex as 0xNNNN)

+#   Control character mappings are not shown in this table, following

+#   Mac OS Gaelic character set uses the standard control characters
+#   at 0x00-0x1F and 0x7F.
+#
+# Notes on Mac OS Gaelic (partly from Michael Everson):
+# -----------------------------------------------------
+#
+#   This is a legacy Mac OS encoding; in the Mac OS X Carbon and Cocoa
+#   environments, it is only supported via transcoding to and from
+#   Unicode.
+#
+#   This character set was developed by Michael Everson of Everson
+#   Typography (everson@evertype.com) and was used for fonts in his
+#   Celtic Utilities and CeltScript font packages for the Mac, as well
+#   as some fonts included with the Irish localizations of Mac OS 6.0.8
+#   and 7.1. Note that while Apple authorized this Irish localization,
+#   it was not a system which shipped with Apple hardware, and was not
+#   otherwise supported by Apple. Fonts conforming to the Mac OS Gaelic
+#   character set are available from Everson Typography
+#   (http://www.evertype.com/celtscript/). Information about the use of
+#   this character set is available at
+#   http://www.evertype.com/celtscript/celtcode.html.
+#
+#   The Mac OS Gaelic encoding shares the script code smRoman (0) with
+#   the standard Mac OS Roman encoding. To determine if the Gaelic
+#   encoding is being used in Mac OS 7-9, you should also check if the
+#   system region code is 81. Otherwise, you can check for particular
+#   fonts that conform to this encoding (since in practice Gaelic fonts
+#   are used with the ordinary US or UK system versions).
+#
+#   This character set is a variant of standard Mac OS Roman, adding
+#   capital and small y with acute, grave, and circumflex; capital and
+#   small w with acute, grave, circumflex and diaeresis; capital and
+#   small b, c, d, f, g, m, p, s, t with dot above; tironian et; small
+#   long r, small long s, and small long s with dot above. It has 36
+#   code point differences from standard Mac OS Roman.
+#
+#   Before Mac OS 8.5, code point 0xDB was CURRENCY SIGN, and was
+#   mapped to U+00A4. In Mac OS 8.5 and later versions, code point
+#   0xDB is changed to EURO SIGN and maps to U+20AC; the standard
+#   Apple fonts are updated for Mac OS 8.5 to reflect this. There is
+#   a "currency sign" variant of the Latin 8 Extended encoding that still
+#   maps 0xDB to U+00A4; this can be used for older fonts.
+#   Note: U+20AC is new with Unicode 2.1; for earlier Unicode
+#   versions, Latin 8 Extended 0xDB may be mapped to private-use
+#   character U+F8A0.
+#
+#   Before Unicode 3.0, code point 0xE4 was PER MILLE SIGN, and was
+#   mapped to U+2030. Since August 1998, code point 0xE4 is changed
+#   to TIRONIAN SIGN ET and maps to U+204A. There is a "per mille
+#   sign" variant of the Mac OS Gaelic encoding that still
+#   maps 0xE4 to U+2030; this can be used for older fonts.
+#   Note: U+204A is new with Unicode 3.0; for earlier Unicode
+#   versions, Mac OS Gaelic was unified with AMPERSAND.
