MFC r258316:
Bug fixes in iconv(3) UTF-7 support.
- Add ' to the list of directly encoded characters and * to the list of optionally directly encoded characters as per RFC 2152.
- In _citrus_UTF7_mbtoutf16 on end of input when the next output character has only been partially decoded, save a copy of the buffer of input characters (not just its length). On the next call with more input characters this buffer is reprocessed together with the new input to form a fully decoded output character.
- At the end of a base64 encoded sequence fully discard '-' (BASE64_OUT) by decrementing psenc->chlen and i. This is needed to make room in psenc->ch (input buffer) in case the next input character starts a new base64 encoded sequence. And also, if this is the end of input and no output character can be returned, this brings the encoder in the initial state as indicated by _citrus_UTF7_stdenc_get_state_desc_generic which is used by the caller to distinguish between no output and partial output.
- In _citrus_UTF7_mbrtowc_priv pass the s parameter (input pointer) directly to _citrus_UTF7_mbtoutf16 instead of a copy (s0). This way s is updated correctly in case of errors.
- In _citrus_UTF7_mbrtowc_priv when called with psenc->surrogate set (previous call did not have enough input), retrieve the previously decoded UTF-16 character from (psenc->cache >> psenc->bits) instead of (psenc->cache >> 2).

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.
