Gabor Kovesdan ad30f8e79b 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.

#
# Three tab-separated columns;
# '#' begins a comment which continues to the end of the line.
# Column #1 is the Mac OS Devanagari code or code sequence
# (in hex as 0xNN or 0xNN+0xNN)
# Column #2 is the corresponding Unicode or Unicode sequence

# The second section maps individual code points.
#
# Within each section, the entries are in Mac OS Devanagari code order.
#
# Control character mappings are not shown in this table, following
# the conventions of the standard UTC mapping tables. However, the
# Mac OS Devanagari character set uses the standard control characters
# at 0x00-0x1F and 0x7F.
#
# Notes on Mac OS Devanagari:
# ---------------------------
#
# 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.
#
# Mac OS Devanagari is based on IS 13194:1991 (ISCII-91), with the
# addition of several punctuation and symbol characters. However,
# Mac OS Devanagari does not support the ATR (attribute) mechanism of
# ISCII-91.
#
# 1. ISCII-91 features in Mac OS Devanagari include:
#
# a) Overloading of nukta
#
# In addition to using the nukta (0xE9) like a combining dot below,
# nukta is overloaded to function as a general character modifier.
# In this role, certain code points followed by 0xE9 are treated as
# a two-byte code point representing a character which may be
# rather different than the characters represented by either of
# the code points alone. For example, the character DEVANAGARI OM
# (U+0950) is represented in ISCII-91 as candrabindu + nukta.
#
# b) Explicit halant and soft halant
#
# A double halant (0xE8 + 0xE8) constitutes an "explicit halant",
# which will always appear as a halant instead of causing formation
# of a ligature or half-form consonant.
#
# Halant followed by nukta (0xE8 + 0xE9) constitutes a "soft
# halant", which prevents formation of a ligature and instead
# retains the half-form of the first consonant.
#
# c) Invisible consonant
#
# The byte 0xD9 (called INV in ISCII-91) is an invisible consonant:
# It behaves like a consonant but has no visible appearance. It is
# intended to be used (often in combination with halant) to display
# dependent forms in isolation, such as the RA forms or consonant
# half-forms.
#
# d) Extensions for Vedic, etc.
#
# The byte 0xF0 (called EXT in ISCII-91) followed by any byte in
# the range 0xA1-0xEE constitutes a two-byte code point which can
# be used to represent additional characters for Vedic (or other
# extensions); 0xF0 followed by any other byte value constitutes
# malformed text. Mac OS Devanagari supports this mechanism, but
# does not currently map any of these two-byte code points to
# anything.
#
# 2. Mac OS Devanagari additions
#
# Mac OS Devanagari adds characters using the code points
# 0x80-0x8A and 0x90-0x91 (the latter are some Devanagari additions
# from Unicode).
#
# 3. Unused code points
#
# The following code points are currently unused, and are not shown
# here: 0x8B-0x8F, 0x92-0xA0, 0xEB-0xEF, 0xFB-0xFF. In addition,
# 0xF0 is not shown here, but it has a special function as described
# above.
#
# Unicode mapping issues and notes:
# ---------------------------------
#
# 1. Mapping the byte pairs
#
# If one of the following byte values is encountered when mapping
# Mac OS Devanagari text - 0xA1, 0xA6, 0xA7, 0xAA, 0xDB, 0xDC, 0xDF,
# 0xE8, or 0xEA - then the next byte (if there is one) should be
# examined. If the next byte is 0xE9 - or also 0xE8, if the first
# byte was 0xE8 - then the byte pair should be mapped using the
# first section of the mapping table below. Otherwise, each byte
# should be mapped using the second section of the mapping table
# below.
#
# - The Unicode Standard, Version 2.0, specifies how explicit
# halant and soft halant should be represented in Unicode;
# these mappings are used below.
#
# If the byte value 0xF0 is encountered when mapping Mac OS
# Devanagari text, then the next byte should be examined. If there
# is no next byte (e.g. 0xF0 at end of buffer), the mapping
# process should indicate incomplete character. If there is a next
# byte but it is not in the range 0xA1-0xEE, the mapping process
# should indicate malformed text. Otherwise, the mapping process
# should treat the byte pair as a valid two-byte code point with no
# mapping (e.g. map it to QUESTION MARK, REPLACEMENT CHARACTER,
# etc.).
#
# 2. Mapping the invisible consonant
#
# It has been suggested that INV in ISCII-91 should map to ZERO
# WIDTH NON-JOINER in Unicode. However, this causes problems with
# roundtrip fidelity: The ISCII-91 sequences 0xE8+0xE8 and 0xE8+0xD9
# would map to the same sequence of Unicode characters. We have
# instead mapped INV to LEFT-TO-RIGHT MARK, which avoids these
# problems.
#
# 3. Additional loose mappings from Unicode
#
# These are not preserved in roundtrip mappings.
#
# U+0958 0xB3+0xE9 # DEVANAGARI LETTER QA
# U+0959 0xB4+0xE9 # DEVANAGARI LETTER KHHA
# U+095A 0xB5+0xE9 # DEVANAGARI LETTER GHHA
# U+095B 0xBA+0xE9 # DEVANAGARI LETTER ZA
# U+095C 0xBF+0xE9 # DEVANAGARI LETTER DDDHA
# U+095D 0xC0+0xE9 # DEVANAGARI LETTER RHA
# U+095E 0xC9+0xE9 # DEVANAGARI LETTER FA
#
# 4. Roundtrip considerations when mapping to decomposed Unicode
#
# Both ISCII-91 (hence Mac OS Devanagari) and Unicode provide multiple
# ways of representing certain Devanagari consonants. For example,
# DEVANAGARI LETTER NNNA can be represented in Unicode as the single
# character 0x0929 or as the sequence 0x0928 0x093C; similarly, this
# consonant can be represented in Mac OS Devanagari as 0xC7 or as the
# sequence 0xC6 0xE9. This leads to some roundtrip problems. First
# note that we have the following mappings without such problems:
#
# ISCII/ standard decomposition of reverse mapping
# Mac OS Unicode mapping standard mapping of decomposition
# ------ ----------------------- ---------------- ----------------
# 0xC6 0x0928 ... LETTER NA 0x0928 (same) 0xC6
# 0xCD 0x092F ... LETTER YA 0x092F (same) 0xCD
# 0xCF 0x0930 ... LETTER RA 0x0930 (same) 0xCF
# 0xD2 0x0933 ... LETTER LLA 0x0933 (same) 0xD2
# 0xE9 0x093C ... SIGN NUKTA 0x093C (same) 0xE9
#
# However, those mappings above cause roundtrip problems for the
# the following mappings if they are decomposed:
#
# ISCII/ standard decomposition of reverse mapping
# Mac OS Unicode mapping standard mapping of decomposition
# ------ ----------------------- ---------------- ----------------
# 0xC7 0x0929 ... LETTER NNNA 0x0928 0x093C 0xC6 0xE9
# 0xCE 0x095F ... LETTER YYA 0x092F 0x093C 0xCD 0xE9
# 0xD0 0x0931 ... LETTER RRA 0x0930 0x093C 0xCF 0xE9
# 0xD3 0x0934 ... LETTER LLLA 0x0933 0x093C 0xD2 0xE9
#
# One solution is to use a grouping transcoding hint with the four
# decompositions above to mark the decomposed sequence for special
# treatment in transcoding. This yields the following mappings to
# decomposed Unicode:
#
# ISCII/ decomposed
# Mac OS Unicode mapping
# ------ ----------------
# 0xC7 0xF860 0x0928 0x093C
# 0xCE 0xF860 0x092F 0x093C
# 0xD0 0xF860 0x0930 0x093C
# 0xD3 0xF860 0x0933 0x093C
